The Origins, Evolution, and Future of a Decentralized Revolution

Introduction

While trying to understand cryptocurrency, I came across blockchain. I found that I understood even less about blockchain than I did about cryptocurrency. The following article is my attempt to explain blockchain to myself. If you have not read my earlier post The Rise of Cryptocurrency, doing so may be helpful for understanding this post.

Blockchain technology was once a niche topic among cryptographers and libertarians who hoped to be shielded from government scrutiny. It has since evolved into a global force reshaping how we think about data, transactions, and trust. Born in the wake of the 2008 financial crisis, blockchain offers a radical transparent alternative to traditional financial institutions.

Today, it underpins not only cryptocurrencies but also supply chains, voting systems, healthcare, and intellectual property. This article explores the history, mechanics, current applications, and future potential of blockchain technology.

1. Origins of Blockchain

Who Created It? The modern concept of blockchain was introduced in 2008 by a pseudonymous developer (or group) known as Satoshi Nakamoto, in a white paper titled Bitcoin: A Peer-to-Peer Electronic Cash System. While Nakamoto’s identity remains unknown, the paper built on earlier work by cryptographers such as David Chaum (digital cash, 1980s) and Nick Szabo (“bit gold”).
Why Was It Developed? Blockchain emerged in response to a global crisis of trust. The 2008 financial meltdown exposed the dangers of opaque, centralized financial systems. Nakamoto’s vision was a decentralized system that did not rely on trust and was an alternative where users wouldn’t need banks or governments to verify transactions.
First Use Case: The original application of blockchain was Bitcoin—the first decentralized digital currency. Many people believe that Bitcoin evolved from blockchain, but in fact, blockchain was created to make Bitcoin feasible. Bitcoin’s blockchain acts as a transparent, time-stamped public ledger to prevent double-spending and centralized tampering.
Key Innovation: The Chain of Blocks, at its core, blockchain is a distributed ledger where transactions are grouped into blocks. Each block is cryptographically linked to the one before it, forming a secure, tamper-resistant chain that is spread across many computer networks.

2. How Blockchain Works

Blockchain operates on several core principles:

Decentralization: Data is stored across a network of nodes (think computers for simplicity) rather than a single server.
Immutability: Once added, a block cannot be altered without changing all subsequent blocks.
Consensus Mechanisms: Agreement is achieved through protocols like Proof of Work or Proof of Stake (explained below).
Transparency with Pseudonymity: Transactions are visible to all but are tied to encrypted addresses—not personal identities.

3. Why Blockchain Is Secure

Cryptographic Hashing: Each block contains a cryptographic hash (repeat) of the previous block’s data. A cryptographic hash is a mathematical function that takes an input (or “message”) and returns a fixed-size string of characters, which appears random. A discussion of it is well beyond the scope of this article (and my understanding as well). Even a tiny change in the data drastically changes the hash. Any tampering becomes immediately obvious, breaking the chain’s integrity.

Decentralization: Every node on the network has a full copy of the blockchain. If a single node is altered, the change is rejected by the others. This makes coordinated attacks extremely difficult, especially on large networks.
Consensus Mechanisms: Blockchain uses mathematical consensus to validate new blocks:
Proof of Work (PoW): Used by Bitcoin; involves solving complex mathematical puzzles. A 51% attack (controlling most of the computing power) is prohibitively expensive and would cost far more than could be realized through manipulation of the blockchain.
Proof of Stake (PoS): Used by Ethereum 2.0 and others; validators stake tokens, risking loss if they act dishonestly. This might be thought of as posting a bond.
Immutability: Once a block is added and validated, it’s nearly impossible to alter. Changing one block would require rewriting all subsequent ones and redoing the work—an impractical task on any meaningful scale.
Public and Private Key Cryptography: Each user has a private key (used to sign transactions) and a public key (used to verify them). This ensures only the rightful owner can authorize a transaction.
Auditability: Most public blockchains are fully transparent. Anyone can audit the ledger, view transaction history, and verify balances—without relying on centralized authorities.

4. Current Uses of Blockchain

Blockchain’s applications now stretch across numerous industries:

Finance Beyond Bitcoin:
Ethereum introduced smart contracts and decentralized apps (dApps). Think of a smart contract as a digital vending machine. You put in a specific input (e.g., cryptocurrency), and the contract automatically performs a pre-programmed action (e.g., transfer of ownership, release of funds). No lawyer, banker, or notary is needed to oversee or verify the transaction.dApps are software programs that run on a blockchain or peer-to-peer network, rather than being hosted on centralized servers.
Decentralized Finance (DeFi) enables peer-to-peer lending, borrowing, and trading without traditional intermediaries.
Stablecoins (e.g., USDC, Tether) offer price stability by pegging cryptocurrencies to government backed currencies.
Cross-border payments are cheaper and faster using blockchain.
Supply Chain Transparency, companies like Walmart, IBM, and Maersk use blockchain for traceability. Example: Lettuce traced from farm to shelf helps speed up food recalls.
Healthcare uses blockchain to secure medical records and track pharmaceuticals. Estonia integrates blockchain into its national health system.
Voting and Governance is supported by trials, like West Virginia’s 2018 blockchain voting pilot, that aim to improve election transparency. Concerns remain about digital vote integrity and security.
Digital Identity & Intellectual Property utilizesblockchaintoallowartists to use Non Fungible Tokens (NFT) to register digital ownership of art. An NFT is a unique digital asset that represents ownership or proof of authenticity of a specific item, such as artwork, music, video clips, virtual real estate, or even tweets, and it’s stored on a blockchain—a decentralized digital ledger. It is used for assets that have no physical existence. Think of it as owning the rights to a computer program.
Self-sovereign identity systems are being developed by companies like Microsoft for developing user-controlled credentials.

5. Criticisms and Challenges

Despite its promise, blockchain faces significant obstacles:

Scalability: Networks like Bitcoin can become slow and costly at high volumes.
Energy Consumption: PoW systems have been criticized for their high carbon footprint. They make high demands on electrical grids and on water systems.
Regulatory Uncertainty: Governments differ widely on how to regulate blockchain and crypto. International agreements will be necessary for advanced implementation but have not yet been established and in most cases have not even begun.
Fraud & Hype: Scams and speculative investments have eroded public trust in some blockchain projects. Because of their decentralized structure, there’s no central authority to guarantee their security. Given that the philosophy behind blockchain is to avoid government oversight, this may always be a problem.

6. The Future of Blockchain

Greener Alternatives: such asProof of Stake (e.g., Ethereum 2.0) significantly reduce energy use and improve scalability.
Central Bank Digital Currencies (CBDCs): Countries like the U.S., China, and Sweden are considering, or in some cases piloting, digital currencies backed by governments and built on blockchain-like infrastructure.
Tokenization of Real Assets allows real estate, art, and even wine to be digitally fractionalized, allowing more people to invest in historically exclusive markets.
Interoperability of block chain means future systems will allow cross-blockchain communication, improving flexibility and usability across networks.
Decentralized Autonomous Organizations (DAOs) can operate through smart contracts and community voting—no CEOs or managers required. Potential applications include governance, philanthropy, and startup funding.

Conclusion

So, do I now fully understand blockchain? Not hardly. But it is important to be aware of it and know that it will have a significant impact on our lives.

Blockchain is more than an esoteric new technology—it’s a reimagining of how trust, authority, and ownership work in a digital society. From its roots in cyber-activism to its integration into governments and corporations, blockchain is reshaping the way we do business.

Its future will depend on whether we manage its risks and harness its power responsibly. Done right, blockchain could form a core part of tomorrow’s digital infrastructure. Done poorly, it could become another overhyped fad that imposes additional burdens on society.

🔑 Key Takeaways

Blockchain is a decentralized ledger that enhances transparency and trust.
It started with Bitcoin but now spans many industries.
Key strengths include immutability, transparency, and security.
Major challenges include scalability, energy use, and regulatory ambiguity.
The future could bring CBDCs, DAOs, interoperability, and asset tokenization.

🫁 Living With COPD

What You Need to Know About This Silent Lung Disease

Chronic Obstructive Pulmonary Disease—better known as COPD—is one of the most common chronic illnesses affecting adults, particularly older adults, worldwide. And yet, it remains underrecognized until it’s well-advanced. In this post, we’ll break down what COPD is, how it develops, who’s at risk, what symptoms to watch for, how it’s treated, and what living with the disease may look like over time.

🚬 What Causes COPD?

At its core, COPD is an inflammatory condition that narrows the airways and damages the alveoli (the tiny air sacs in the lungs). The disease typically results from long-term exposure to lung irritants. Here are the main culprits:

Smoking (cigarettes, cigars, pipes) – the #1 cause
Occupational hazards – coal dust, fumes, silica, grain dust
Indoor air pollution – wood-burning stoves, biomass fuel
Outdoor pollution – especially in cities or industrial zones
Genetics – especially a rare condition called alpha-1 antitrypsin deficiency

Most people who develop COPD are over age 40 and have a history of smoking, but it’s not exclusive to smokers.

🧬 How COPD Develops

In people with COPD, years of exposure to irritants cause chronic inflammation in the airways. This leads to:

Swelling and narrowing of the air passages
Destruction of alveolar walls (especially in emphysema)
Increased mucus production (as seen in chronic bronchitis)
Air trapping in the lungs, reducing oxygen exchange

It’s a slow and irreversible process. By the time symptoms appear, significant lung damage may have already occurred.

😮‍💨 Symptoms: What to Watch For

COPD symptoms often sneak up gradually and are easy to ignore or misattribute to aging. Common signs include:

Persistent cough (especially one that produces phlegm)
Shortness of breath (especially on exertion)
Wheezing or noisy breathing
Chest tightness
Frequent respiratory infections
Fatigue or lack of stamina
Bluish lips or fingertips in later stages (a sign of low oxygen)

Episodes where these symptoms suddenly worsen are called exacerbations—and they can be serious.

🔬 How COPD is Diagnosed

The gold standard for diagnosis is a spirometry test.

📊 What’s the FEV1/FVC Ratio?

This simple lung test measures how much air you can force out in one second (FEV1) and the total amount you can exhale after a deep breath (FVC). If your FEV1/FVC ratio is less than 0.70, that’s a strong sign of airflow obstruction—a hallmark of COPD.

✅ Normal: FEV1/FVC ≥ 0.75–0.80
❌ COPD: FEV1/FVC < 0.70

Doctors may also order chest X-rays, blood oxygen tests, or CT scans to rule out other conditions or assess lung damage.

💊 Treating COPD: What’s Possible?

There’s no cure—but treatment can help you feel better, breathe easier, and live longer. Here’s how it’s managed:

🚭 1. Stop Smoking

This is the most important intervention. Quitting smoking slows progression—no matter what your stage.

🌬️ 2. Inhalers (Bronchodilators)

These help open narrowed airways. There are short-acting types for quick relief and long-acting types for daily control.

🌡️ 3. Inhaled Steroids

Used to reduce inflammation and prevent flare-ups, especially for people who have frequent exacerbations.

🏃‍♂️ 4. Pulmonary Rehab

A supervised program that includes exercise training, nutrition advice, and education. Proven to improve quality of life.

🧪 5. Oxygen Therapy

Recommended if blood oxygen is low. Some people need it 24/7; others only during activity or sleep.

😷 6. Surgical Options

Rarely, procedures like lung volume reduction or lung transplants are used in severe cases.

📈 How COPD Progresses

The GOLD system stages COPD into four levels based on spirometry and symptom severity:

Stage	FEV1 % Predicted	Description
I	≥80%	Mild
II	50–79%	Moderate
III	30–49%	Severe
IV	<30%	Very Severe

As COPD worsens, daily tasks like climbing stairs, shopping, or even talking can become exhausting. Exacerbations may increase in frequency and severity.

⏳ What’s the Outlook?

COPD is a chronic, lifelong condition. But the prognosis varies:

If caught early and managed well, many people live long, active lives.
If left untreated, it can lead to respiratory failure, heart problems, and frequent hospitalizations.
Advanced cases can progress to Cor pulmonale (right-sided heart failure) which may develop due to chronic low oxygen levels and pulmonary hypertension.
Respiratory failure can occur in advanced stages, requiring mechanical ventilation.

Doctors sometimes use a tool called the BODE Index to estimate risk. It includes:

Body mass index (low BMI = worse outlook)
Obstruction (how bad the lung damage is)
Dyspnea (breathlessness level)
Exercise tolerance (walking distance)

🛠️ The Bottom Line

COPD is common, serious, and often preventable. If you have a chronic cough, get winded easily, or have a history of smoking or exposure to lung irritants, talk to your doctor about spirometry testing.

Lifestyle changes, especially quitting smoking, make the biggest difference. Medications and rehabilitation programs can dramatically improve your quality of life.

Early action matters—and it’s never too late to start breathing better.

Ramp Season in Appalachia

By John Turley

On April 16, 2025

In Appalachia, Food and Drink

The Wild Delicacy with a Pungent Reputation

Introduction

Every spring, frenzy erupts in the forests of Appalachia. It’s ramp season—the time of year when foragers, chefs, and food lovers alike scramble for a taste of Allium tricoccum, better known simply as “ramps.” These wild leeks are native to eastern North America and have been part of regional cuisine, especially in the Appalachian Mountains, for generations. But while ramps are beloved by some for their intense flavor, others object to their strong odor. More recently, there has been controversy over the ethics of harvesting them.

Where do you find ramps?

Ramps typically grow in rich, moist woodlands from Georgia to Canada, with a heavy concentration in the Appalachian region, including West Virginia, Kentucky, Tennessee, and North Carolina. They thrive in shady spots, often under beech, birch, or maple trees. Patches of ramps emerge in early spring, usually from late March to early May, depending on elevation and latitude. The plant resembles a small scallion, with smooth, broad leaves and a purplish stem. Both the leaves and the bulb are edible, and they carry a flavor often described as a cross between garlic and onion.

Traditionally, ramps were harvested by hand, with foragers pulling up the whole plant, bulb and all. However, the surge in popularity—fueled in part by chefs and food writers discovering their unique taste—has led to overharvesting in some areas. Today, sustainable harvesting practices are strongly encouraged. These include taking only one leaf per plant or harvesting just a small portion of any given patch to allow for regeneration. In some public lands, such as national parks, ramp harvesting is now restricted or banned altogether due to conservation concerns.

What do you do with them?

The bulb of the ramp—the white, root-like portion at the base—has the strongest odor and flavor. That’s where the pungent, garlicky-onion aroma really hits its peak. It’s rich in sulfur compounds (like those found in garlic), which is why the smell can linger on your breath—and in your kitchen—for days.

The leaves, in contrast, are milder and more herbaceous. They still carry that signature ramp flavor, but with a fresher, greener tone. Many foragers actually prefer using the leaves for things like pestos and sautés, partly to preserve the plant (since you can harvest one leaf and leave the bulb) and partly for the gentler taste.

So, if you’re after full-on ramp intensity, go for the bulb. If you want a subtler approach (or plan to be around other people), stick with the leaves.

As for how ramps are used, they’re astonishingly versatile. In traditional Appalachian kitchens, ramps are often fried with potatoes or scrambled with eggs. Ramps will frequently appear in Southern dishes like pimento cheese, corn bread, and brown beans. Modern chefs toss them into pastas, pickle them, or char them on the grill. More recently, ramps have appeared in pesto, risotto, and aioli. I recently tried ramp waffles with ramp butter—not a fan. I have also seen ramp wine and ramp ice cream but I’m not ready to try them.

The flavor is bold (some say obnoxious) and lingering—fans adore it, but detractors complain that it overstays its welcome. The smell of raw ramps has been compared to extremely potent garlic and eating them can leave a person with a powerful body odor for days. Some schools and workplaces in ramp-happy regions unofficially discourage bringing them for lunch. When I was younger, I remember kids being sent from school after eating too many ramps. I thought about it, but decided school wasn’t as bad as living with ramp odor.

The ramp’s cult-like status has sparked a larger conversation about food ethics and cultural respect. For many Appalachian communities, ramps are more than a trendy ingredient; they’re a cherished sign of spring, rooted in local tradition and memory. Commercialization by outside markets has created tension between tradition and profit, raising questions about who gets to define their value.

In the end, ramps remain a symbol of Appalachia’s deep culinary roots—an edible wild treasure that’s as complex in its social meaning as it is in taste. Whether you’re a die-hard fan or someone who politely passes on the smell or someone who makes every effort to avoid them, ramps are a reminder that even humble woodland plants can stir strong opinions.

The Rise of Cryptocurrency

What Is It, How It Does It Work, and Who’s Using It?

I’ve never really understood cryptocurrency and as a result I haven’t paid much attention to it. Recently Donald Trump signed his Executive Order “Strengthening American Leadership in Digital Financial Technology. The Executive Order established the “Presidential Working Group On Digital Asset Markets”, to explore the creation of a national digital asset (cryptocurrency) stockpile.

That’s when I decided it was time to find out more about it. And, being a guy, my first thought was to just go and buy some. It turned out to be a little more complicated than walking into your local bank and asking to buy a Bitcoin.

To begin with, the current value of a Bitcoin is in excess of $83,000. Most cryptocurrency exchanges allow fractional purchases, some as low as $10. The transaction fee will run about 20% of a small purchase, so it may not be a particularly good investment at that level. The fee is a lower percentage for larger purchases.

You can purchase cryptocurrency such as Bitcoin through cryptocurrency exchanges. There are at least three reputable platforms available in the United States. Bitcoin can also be purchased in small amounts through PayPal and Venmo.

Once you’ve made your purchase, you’ll have to have a Bitcoin wallet, where you will store your Bitcoins. A digital wallet is like a bank account for Bitcoins but with highly sophisticated security. There are two primary types. The custodial wallet is managed by a third-party service and is easy to use, but you don’t control the privacy keys—a serious consideration if you are making a large purchase. There are the non-custodial wallets where you have full control over your privacy key. The most common of these is the Bitcoin.com wallet. It’s user friendly and mobile according to its website.

One thing to consider. Bitcoin purchases for the most part require full identification including Social Security number. This is based on money laundering regulations. The only exception to this is the Bitcoin ATMs (vending machines) that usually only require a driver’s license number and a cell phone number. However, only very small purchases are available through these ATM’s.

Cryptocurrency may seem like a recent invention, but the ideas behind it go back several years. Today, it’s more than a buzzword, it’s a financial tool, an investment asset, and for some, even a national currency. In this post, we’ll explore where crypto came from, how it gets its value, how it’s used in the real world, and which governments (if any) treat it like real money.

Where It All Began: The Origin of Cryptocurrency

Cryptocurrency’s origin begins with a previously unknown person—or possibly a group—known only as Satoshi Nakamoto. In 2008, Nakamoto published a white paper titled “Bitcoin: A Peer-to-Peer Electronic Cash System.” A few months later, in January 2009, the Bitcoin network was officially launched with the mining of the first block, called the Genesis Block. This marked the birth of the world’s first viable cryptocurrency, Bitcoin.

The purpose was to create a form of money that could operate without the control of governments or financial institutions. Bitcoin was designed to be decentralized, transparent, and secure—made possible by blockchain technology. The blockchain is a digital ledger, distributed across thousands of computers, that records every transaction made in the network. Once data is entered, it’s nearly impossible to change—giving it an edge over traditional banking records when it comes to fraud prevention. Earlier attempts to develop a digital currency like eCash and b-money failed because they couldn’t solve the problem of security: protecting their crypto from unauthorized duplication.

By 2011 Nakamoto vanished, leaving a final message that they had moved on to other things. Nakamoto is believed to have mined about 1,000,000 bitcoins which are still sitting untouched in a known wallet address. At today’s prices Nakamoto’s Bitcoins are worth billions. Why did Nakamoto do it? No one knows.

What Gives Crypto Its Value?

One of the most common questions about cryptocurrency is: “What gives it value?”

Unlike the U.S. dollar, which is backed by the full faith and credit of the government (called a fiat currency in modern financial jargon), most cryptocurrencies are not backed by a either a physical commodity or government guarantee. Instead, their value comes from a mix of:

Scarcity: Most cryptocurrencies have a cap on how many coins can exist. For example, Bitcoin is limited to 21 million coins. That built-in scarcity is one reason why people compare it to gold.
Utility: A coin that can be used for more than just speculation—such as transferring money quickly or executing smart contracts—tends to be more valuable.
Network Adoption: The more people who use or invest in a cryptocurrency, the more valuable it tends to become. This is often called the “network effect.”
Speculation: Let’s be honest, a lot of crypto value is driven by people buying low and hoping to sell high. That makes crypto prices volatile, which is both a risk and a reward depending on your timing.

Cryptos like Bitcoin and its major competitor Ethereum gain and lose billions in value in a single day, driven by news, regulation, and even tweets.

Bitcoins are generated through dedicated blockchain technology which ensures their safety and prevents them from being duplicated. As a result, many people view them as a store of value (digital gold). They can also be used as a medium of exchange although that is less common due to volatility and high transaction fees.

There’s another type of cryptocurrency called the meme coin. They often start as jokes or are done by some people as a source of revenue. They have little or no real-world use. They rely on community hype and social media to generate popularity and value. They don’t have their own blockchain, instead they’re built on top of existing platforms. They’re usually created quickly with minimal technical barriers and their security and functionality vary widely.

The best-known meme coin is the $TRUMP coin. It was released just before Donald Trump’s inauguration. A $TRUMP coin reached a high of $75.35 on January 19th, 2025, but it quickly lost almost all value. A $TRUMP coin is currently worth about 27 cents. The Trump family and their associates made millions on transaction fees while investors lost massively in the market. I would not consider meme coins as a real invetment. If you purchase one, consider it as a hobby.

A new advancement in the cryptocurrency scene is the Stablecoin. This type of cryptocurrency is designed to maintain a stable value. It is usually pegged to a traditional asset like the US dollar, the Euro or perhaps gold. The goal is to offer the benefits of cryptocurrency, like fast digital transactions and decentralized access, without the wild price swings seen with other coins like Bitcoin.

Most Stablecoins are backed in one of three ways:

Fiat backed (most common): for example, for every Stablecoin issued a dollar (or equivalent) is held in reserve. This could be considered a digital version of cash held in a bank account.
Crypto backed: Each Stablecoin is backed by other crypto currencies but is usually over collateralized to guard against volatility. For example, $150.00 worth of a regular cryptocurrency is held to issue $100 worth of Stablecoin.
Algorithmic: Stablecoin uses software and smart contracts to control the coin supply and keep the price stable with no actual reserve assets. The most famous example of this was TerraUSD which had a spectacular collapse in 2022.

Stablecoins are designed to a hedge against volatility in the standard crypto markets. They provide the same fast cheap international payments as other cryptocurrency and can provide dollar like stability in countries with unstable currencies. Fiat based coins are generally seen as more reliable because they are frequently audited and are regulated more closely. Others, especially algorithmic ones, have greater risk.

How Is Cryptocurrency Used?

People use cryptocurrency in several different ways, and the list is growing:

1. Digital Payments

Crypto was originally created to be a medium of exchange. Some online and brick-and-mortar retailers accept Bitcoin, Ethereum, or other coins. Services like PayPal and Cash App also allow crypto transactions. However, due to high transaction fees and slow processing times (especially for Bitcoin), it’s not exactly the most convenient way to buy your morning coffee.

2. Investment and Speculation

Most people today use crypto as an investment. Others trade coins daily to make quick profits, a practice known as day trading. Like with the stock market, day trading is a risky business—crypto prices can swing wildly based on rumors or regulatory changes.

3. DeFi (Decentralized Finance)

DeFi is a rapidly growing branch of the crypto world. It allows people to borrow, lend, and earn interest on crypto without going through banks. Platforms like Uniswap and Aave are examples of DeFi services that operate on Ethereum’s blockchain.

4. NFTs and Digital Ownership

A non-fungible token (NFT) is a unique digital asset that represents ownership or proof of authenticity of a specific virtual item, such as artwork, music, video clips, virtual real estate, or even tweets, that is stored on a blockchain—a decentralized digital ledger. Its uniqueness is encoded in metadata and tracked on the blockchain, allowing anyone to verify who owns a particular NFT and ensuring that it can’t be duplicated or counterfeited. (It is beyond me why anyone would spend real money for virtual ownership.)

5. Remittances

Crypto can be a low fee way to send money across borders, especially to countries where banking systems are weak or expensive. Some developing nations have embraced this use enthusiastically.

Is Any Government Using It as Legal Tender?

Yes—but just one (so far): El Salvador.

In September 2021, El Salvador became the first country in the world to adopt Bitcoin as legal tender. That means businesses must accept it alongside the U.S. dollar (which is also legal tender there). The country launched a national crypto wallet called “Chivo,” gave citizens a $30 bonus in Bitcoin to download it, and is even planning “Bitcoin City,” powered by geothermal energy from a volcano.

The move has been controversial. Critics argue Bitcoin’s volatility makes it a poor substitute for cash. Citizens have complained about wallet bugs and transaction errors. On the other hand, the government sees it as a way to attract foreign investment and reduce dependence on traditional banks.

Despite rumors to the contrary, there is no evidence that the US is using Bitcoin to pay El Salvadore to imprison US deportees.

More recently, the Central African Republic is in the process of declaring Bitcoin legal tender, but with far less fanfare and infrastructure than El Salvador. Other countries, like Ukraine, have legalized the use of crypto for payments but stop short of declaring it legal tender. Most other nations take a cautious or skeptical approach.

Is It Real Money?

That depends on how you define money.

Cryptocurrency satisfies some of the classic definitions: it’s a medium ofexchange, a store of value, and (sometimes) a unit of account. But most governments still don’t recognize it as “money” in the legal sense. In the U.S., the IRS treats crypto as property for tax purposes, not as currency. That means every time you buy a coffee with Bitcoin, you technically owe capital gains tax if it’s gone up in value since you bought it.

The Federal Reserve and other central banks are exploring Central Bank Digital Currencies (CBDCs) as an official alternative. These would be government-backed digital dollars, unlike Bitcoin, which is decentralized. Think of it as crypto with guardrails.

Final Thoughts

Cryptocurrency is still in its Wild West phase. It’s a fascinating mix of finance, technology, and ideology. While it’s unlikely to replace national currencies anytime soon, it’s already reshaping how people think about money, investing, and even trust in future assets.

Will more countries follow El Salvador’s lead? Will governments roll out their own digital currencies? Or will crypto remain a fringe asset class for techies and risk-takers? That’s still up in the air—but one thing’s for sure: crypto is no longer just a financial experiment. But I must wonder how good an investment it is if you can buy crypto from a vending machine in a convenience store.

Am I ready to jump into the crypto market? I don’t think so — at least not yet. Well, maybe a few dollars just for fun.

Understanding Prostate Cancer: What Every Man Needs to Know

Prostate Cancer: An Introduction

Prostate cancer is one of the most common cancers among men; the American Cancer Society estimates that approximately one in eight men will be diagnosed with it at some point in their lives.

Prostate cancer is the second leading cause of cancer death in men, after lung cancer. However, most men diagnosed with prostate cancer do not die from the disease.

The five-year survival rate for localized and regional prostate cancer is nearly 100%, thanks to advances in early detection and treatment. Even for men with more advanced disease, treatments such as hormone therapy, radiation, and newer systemic therapies have improved survival outcomes; still, in some cases, prostate cancer can be aggressive and life-threatening.

That said, prostate cancer remains a significant public health concern. The American Cancer Society estimates that approximately 34,000 men in the U.S. died from prostate cancer in 2024. The risk of death increases with more aggressive cancer types, higher Gleason scores, and cancer that has spread to distant organs such as the bones.

In this article we will explore key aspects of prostate cancer, including diagnostic tools such as PSA and the Gleason score, the various treatment options available, and the debate surrounding prostate cancer screening, particularly for men over 70.

Prostate-Specific Antigen (PSA) Test: A Controversial Screening Tool

One of the primary tools used to screen for prostate cancer is the prostate-specific antigen (PSA) blood test. PSA is a protein produced by both normal and cancerous prostate cells, and elevated levels of PSA in the blood can indicate the presence of prostate cancer. However, an elevated PSA level does not always mean cancer is present, as benign conditions like prostatitis (inflammation of the prostate) or benign prostatic hyperplasia (BPH, an enlarged prostate) can also cause high PSA levels.

The PSA test has been at the center of much debate over the past few decades. On the one hand, it has undoubtedly led to earlier detection of prostate cancer, sometimes before any symptoms appear. On the other hand, the PSA test is not a perfect screening tool. It can lead to overdiagnosis and overtreatment of cancers that may never have become clinically significant. Many prostate cancers grow so slowly that they would not have caused harm during a man’s natural lifespan, yet once detected, patients may undergo unnecessary treatments with side effects such as urinary incontinence and erectile dysfunction.

Because of these limitations, the decision to undergo PSA screening should be made after a thorough discussion between the patient and his healthcare provider, considering individual risk factors such as age, family history, and race. Additionally, prostate cancer tends to develop at a younger age in African American men and it is generally recommended that consideration be given to initiate screening beginning around age 45, or even earlier if there’s a strong family history. Additionally, African American men are more likely to be diagnosed with aggressive forms of prostate cancer, leading to poorer outcomes.

In a prior post on medical guidelines, I discussed my personal experience with PSA screening and my diagnosis with prostate cancer.

The Gleason Score: A Key Factor in Diagnosis

Once a prostate cancer diagnosis is confirmed, typically via biopsy, one of the most important prognostic tools is the Gleason score. The Gleason score is a grading system that assesses the aggressiveness of prostate cancer cells under a microscope. Pathologists examine the prostate tissue samples and assign two numbers based on the appearance of the cancer cells. The appearance of cancer cells is evaluated, and each area of abnormal cells is assigned a number on a scale from 1 to 5, with 5 being the most abnormal. (In clinical practice today, grades 1 and 2 are almost never used.) The first number is the most common area, and the second number is the next most common. These two numbers are then added together to give a composite Gleason score between 6 and 10. There is one caveat; not all scores are equal. For example, while 4 + 3 and 3 + 4 both produce a score of 7, the former is more significant because its most common area is of a higher grade.

A Gleason score of 6 typically indicates low-grade cancer that is less likely to spread and may grow slowly.
Scores of 7 suggest an intermediate risk, with some potential for more aggressive growth.
Scores of 8 to 10 represent high-grade cancer that is more likely to grow quickly and spread to other parts of the body.

The Gleason score plays a crucial role in determining treatment options. For instance, low-grade cancers may be candidates for active surveillance, where the patient is closely monitored without immediate treatment. In contrast, high-grade cancers may require more aggressive intervention, such as surgery or radiation therapy. It is also important to recognize that a biopsy may miss an area of high-grade tumor giving an artificially low Gleason score, although with modern use of MRI this is less likely.

Treatment Options

Prostate cancer treatment decisions depend on several factors, including the Gleason score, PSA level, the stage of the cancer (whether it has spread beyond the prostate), the patient’s overall health, and personal preferences.

1. Active Surveillance

Active surveillance is often recommended for men with low-risk prostate cancer, especially those who are older or have other significant health problems. Instead of immediate treatment, the patient is closely monitored with periodic PSA tests, digital rectal exams (DRE), and biopsies to detect any signs of progression. The goal is to avoid over-treatment while keeping a close eye on the cancer in case it becomes more aggressive.

2. Surgery (Radical Prostatectomy)

For men with localized prostate cancer, especially those with higher Gleason scores or younger patients, surgery may be recommended. A radical prostatectomy involves removing the entire prostate gland and some surrounding tissues. While surgery offers the potential for a cure, it comes with risks of side effects such as incontinence and erectile dysfunction, depending on factors such as nerve preservation during the procedure. The newer robotic surgical techniques have fewer side effects than the older open technique.

3. Radiation Therapy

Radiation therapy is another option for treating localized or locally advanced prostate cancer. External beam radiation or brachytherapy (internal radiation) can target the cancerous cells while sparing healthy tissue. Radiation therapy is often used as an alternative to surgery or in combination with other treatments. The side effects are similar to those of surgery, including urinary and sexual dysfunction, though the timing and severity of these side effects may differ.

4. Hormone Therapy (Androgen Deprivation Therapy, or ADT)

Prostate cancer growth is often fueled by androgens, the male hormones such as testosterone. Hormone therapy aims to lower androgen levels or block their effects on prostate cancer cells, which can slow the growth of the cancer. Hormone therapy is typically used in cases where the cancer has spread beyond the prostate or recurred after previous treatment. It may also be used in combination with radiation for high-risk cancers.

5. Chemotherapy and Other Systemic Treatments

For men with advanced prostate cancer that has spread to other parts of the body (metastatic cancer), chemotherapy may be an option. Other newer treatments, such as immunotherapy and targeted therapies, are being developed to improve outcomes for patients with advanced disease.

The Age 70 Screening Debate

One of the most debated topics in prostate cancer screening is when to stop PSA testing. Many organizations, including the U.S. Preventive Services Task Force (USPSTF), recommend that routine PSA screening should generally stop at age 70. The rationale behind this recommendation is that prostate cancer often grows very slowly, and older men are more likely to die from other causes before prostate cancer becomes life-threatening. Moreover, the risks of treatment often outweigh the benefits for older men with low-risk cancers.

However, this recommendation is not without controversy. Some experts argue that healthy older men, particularly those with a life expectancy of 10 years or more, should continue to be screened because they may still benefit from early detection and treatment. Discontinuing screening might result in missing aggressive cancers that could benefit from early intervention. Some studies suggest that older men who continue screening are less likely to be diagnosed with high-risk disease.

As with other aspects of prostate cancer care, the decision should be individualized based on the patient’s health, preferences, and overall risk profile.

Conclusion

Prostate cancer is a complex disease with a wide range of outcomes, from slow-growing tumors that may never cause harm to aggressive cancers that can be fatal. Screening and diagnostic tools such as the PSA test and Gleason score are valuable, but they must be used carefully to avoid over-diagnosis and over-treatment. Treatment options range from active surveillance to surgery and radiation, and the choice depends on the individual patient’s cancer characteristics and overall health. Finally, the decision to stop PSA screening at age 70 should be made on a case-by-case basis, with the goal of balancing the benefits of early detection against the potential harms of treatment.

Prostate cancer is a serious diagnosis, but with appropriate screening and treatment, many men can live long and healthy lives.

What Is Fascism Anyway?

By John Turley

In Commentary, History, Politics

Fascist! The very word conjures up images of totalitarianism, militarism, suppression of dissent and brutality. Unfortunately, it’s become a ubiquitous portion of our political discourse. Each side, at one time or another, has accused the other of being fascist. But what do they really mean by fascist? Do they understand the definition and the reality of fascism? Or do they simply mean: “I disagree with you, and I really want to make you sound evil.”

I decided I needed to know more about fascism, so I’ve done some research, and I’d like to share the results with you. As I frequently do, I’ll start with the dictionary definition. According to Merriam-Webster fascism is a political philosophy, movement, or regime that exalts nation and often race above the individual and that stands for a centralized autocratic government headed by a dictatorial leader, severe economic and social regimentation, and forcible suppression of opposition.

As with many dictionary definitions, it gives us the 50,000-foot view without any real detail. What I’d like to do is cover the origins of fascism, its basic principles and how it rose to prominence in the middle of the 20th century. I also want to compare fascism to communism—another ideology that shaped much of the 20th century—and to provide insights into the differences and similarities between these two systems.

The Origins of Fascism

Fascism emerged in the early 20th century, primarily in Italy, as a reaction to the perceived failures of liberal democracy and socialism. The term itself comes from the Italian word “fascio,” meaning a bundle or group, symbolizing unity and collective strength. It also references fasces, a bundle of rods tied around an ax symbolizing authority in the Roman Republic. It was appropriated as a symbol by Italian fascists in an attempt to identify with Roman history, much as American patriotic symbols are being appropriated by the radical right in the U.S. today.

Benito Mussolini, an Italian political leader, is often credited as the founder of fascism. He established the groundwork for first fascist regime in Italy beginning in 1922 after he was appointed Prime Minister. Fascism arose in a period of social and economic turmoil following the First World War. Many people in Europe were disillusioned with the existing political systems, which they believed had failed to prevent the war and its devastating consequences. The post-war economic instability, along with fears of communist revolutions like the one in Russia, provided fertile ground for the rise of fascist movements.

Moussolini, together with Italian philosopher Giovanni Gentile, published “The Doctrine of Fascism” (La Dottrina del Fascismo) in 1932, after he had consolidated political power in his hands. It lays out the guiding principles and theoretical foundations of fascism, stressing nationalism, anti-communism, the glorification of the state, the belief in a strong centralized leadership, and the rejection of liberal democracy.

The Philosophical Basis of Fascism

Fascism is rooted in several key philosophical ideas:

Nationalism and Militarism: Fascism places the nation or race at the center of its ideology, often elevating it to a quasi-religious status. The state is seen as a living entity that must be protected and expanded through internal police action and external military strength.
Authoritarianism: Fascists reject democratic institutions, believing that a strong, centralized authority is necessary to maintain order and achieve national greatness. Individual freedoms are subordinated to the needs of the state.
Anti-Communism and Anti-Liberalism: Fascism is explicitly opposed to both communism and liberal democracy. It views communism as a threat to national unity and social order, while liberal democracy is seen as weak and indecisive.
Social Darwinism: Fascists often believe in the idea of the survival of the fittest, applying this concept to nations and races. They argue that conflict and struggle are natural and necessary for the advancement of the state.

Implementation and Practice of Fascism

Fascism has been implemented in various forms, with Italy under Mussolini and Nazi Germany under Adolf Hitler being the most prominent examples. In practice, fascist regimes are characterized by:

Centralized Power: Fascist governments concentrate power in the hands of a single leader or party, often through the use of propaganda, censorship, political repression, and mass imprisonment and execution of opponents.
State Control of the Economy: While fascists generally allow for private ownership, they maintain strict control over the economy, directing resources toward the state’s goals, particularly militarization.
Suppression of Dissent: Fascist regimes are intolerant of opposition, often using violence, imprisonment, and even assassination to eliminate political rivals and suppress dissent.
Cult of Personality: Fascist leaders often create a cult of personality, presenting themselves as the embodiment of the nation and its destiny.

Comparing Fascism and Communism

While both fascism and communism reject liberal democracy, they differ significantly in their goals and methods.

Philosophical Differences:
- Fascism: As mentioned earlier, fascism emphasizes nationalism, authoritarianism, and social hierarchy. It seeks to create a strong, unified state that can compete with other nations on the global stage.
- Communism: Communism, based on the ideas of Karl Marx, advocates for a classless society where the means of production are owned collectively. It seeks to eliminate private property and achieve equality among all citizens.
Economic Systems:
- Fascism: Fascists allow for private ownership but maintain state control over key industries and direct economic activity to serve the state’s interests.
- Communism: Communism advocates for the abolition of private property, with all means of production owned and controlled by the state (or the people in theory). The economy is centrally planned and managed.
Political Structures:
- Fascism: Fascist regimes are typically one-party states with a strong leader at the top. Political pluralism is non-existent, and the government exercises strict control over all aspects of life.
- Communism: Communist states are also typically one-party systems, but they claim to represent the working class. In practice, these regimes often become highly centralized and authoritarian or totalitarian, similar to fascist states.

Comparative Examples

Italy and Nazi Germany (Fascism): Both Mussolini’s Italy and Hitler’s Germany exemplify fascist regimes. They were characterized by aggressive nationalism, military expansionism, and the suppression of political opposition. Hitler’s regime, however, took these ideas to their most extreme and horrifying conclusion with the Holocaust, a genocide driven by racist ideology.
Soviet Union (Communism): The Soviet Union under Joseph Stalin provides a clear example of a totalitarian communist state. The government abolished private property, collectivized agriculture, and implemented central planning. Political repression was severe, with millions of people imprisoned, starved to death or executed during Stalin’s purges. It is important to recognize that Stalinist communism differed significantly from the theoretical communism of Karl Marx.

Conclusion

Fascism and communism, despite their profound differences, share certain similarities in practice, particularly in their authoritarianism and intolerance of dissent. However, their philosophical foundations and goals are fundamentally different: fascism seeks to elevate the nation above all else, while communism theoretically aims to create a classless society. Understanding these ideologies and their historical manifestations is crucial for anyone interested in the political history of the 20th century and its lasting impact on the world today.

We can use our understanding of fascism and its comparison to democracy to ask important questions. What kind of government do we want? Are there any possible crossovers or compromises between the two? And, importantly, should there be?

Postscript

Many of the ideas in this post were inspired by two excellent books on the subject, “The Origins of Totalitarianism” by Hannah Arendt and “Fascism: A Warning” by Madeleine Albright.

A Brief History of the U.S. Navy Medical Corps

The U.S. Navy Medical Corps has a history that evolves from a humble beginning during the Revolutionary War to its current role as a vital component of modern military medicine. The Medical Corps ensures the health and well-being of sailors, Marines, and their families, while contributing to public health and advancements in medical science.

Origins in the Revolutionary War

The roots of Navy medicine trace back to the Revolutionary War, when medical care aboard ships was primitive at best. Shipboard surgeons, often lacking formal medical training, treated injuries and disease with the limited tools and knowledge available to them. In the early days of the U.S. Navy, physicians served without formal commissions, often receiving temporary appointments for specific cruises. Their primary tasks included amputations, treating infections, and caring for diseases like scurvy and dysentery.

In 1798, Congress formally established the Department of the Navy, creating the foundation for organized medical care within the naval service. Surgeon Edward Cutbush published the first American text on naval medicine in 1808. The Naval Hospital Act of 1811 marked another milestone, authorizing the construction of naval hospitals to support the growing fleet.

Establishment of the Navy Medical Corps (1871)

The U.S. Navy Medical Corps was officially established on March 3, 1871, by an act of Congress. This legislation created a formal medical staff to support the Navy, setting standards for the recruiting and training naval physicians. These physicians were initially known as “Surgeons” and “Assistant Surgeons,” tasked with providing care on ships and at naval hospitals. The act granted Navy physicians rank relative to their line counterparts, acknowledged their role as a staff corps, and established the title of “Surgeon General” for the Navy’s senior medical officer.

During this period, the Navy Medical Corps began to expand its scope. It embraced emerging medical technologies and scientific discoveries, setting the stage for its later contributions to public health and medical innovation.

The Navy Hospital Corps

The U.S. Navy Hospital Corps was established on June 17, 1898. Its creation was prompted by the increased medical needs during the Spanish-American War. Since then, the enlisted corpsmen have served in every conflict involving the United States, providing critical medical care on battlefields, aboard ships, and in hospitals worldwide.

Corpsmen are trained to perform a wide range of medical tasks, including emergency battlefield triage and treatment, surgery assistance, and disease prevention. They are often embedded directly with Marine Corps units, making them indispensable on the battlefield.

The Hospital Corps is the most decorated group in the U.S. Navy. To date, its members have earned numerous high-level awards for valor, including: 22 Medals of Honor, 182 Navy Crosses, 946 Silver Stars, and 1,582 Bronze Stars.

World Wars and the Expansion of Military Medicine

Both World War I and World War II were transformative for the Navy Medical Corps. During World War I, Navy medical personnel treated injuries and illnesses both aboard ships and in field hospitals. Their efforts were instrumental in managing wartime epidemics, including the devastating 1918 influenza pandemic.

World War II brought further advancements. The Navy Medical Corps played a pivotal role in addressing the challenges of warfare in diverse climates, including tropical diseases in the Pacific Theater. It also pioneered methods for treating trauma, burns, and psychiatric conditions.

Cold War Era and Modernization

The Cold War era marked a time of significant innovation for the Navy Medical Corps. The establishment of the Navy Medical Research Institutes advanced studies in areas such as tropical medicine, submarine medicine, and aerospace medicine. These efforts supported the Navy’s global missions and contributed to broader medical advancements.

In the latter half of the 20th century, Navy medical personnel became key players in humanitarian missions, responding to natural disasters and providing aid in conflict zones. Their expertise in public health, infectious disease control, and trauma care enhanced the Navy’s ability to spread goodwill worldwide.

Modern Contributions and Future Challenges

Today, the Navy Medical Corps supports both military readiness and global health. Its personnel provide care on ships, submarines, aircraft carriers, and for Marine Corps forces, and at shore-based facilities. They also participate in humanitarian missions and disaster response, reflecting the Navy’s commitment to a broader vision of security and well-being.

In recent years, Navy medicine has faced challenges such as the COVID-19 pandemic, addressing mental health issues among service members, and adapting to emerging threats like climate change and cyber warfare defense. These challenges underscore the evolving role of the Navy Medical Corps in a complex world.

From its early days of rudimentary care to its modern role in global health and innovation, the U.S. Navy Medical Corps has been a cornerstone of military medicine. Its contributions extend beyond the battlefield, shaping public health, medical research, and humanitarian efforts worldwide.

As the Navy Medical Corps continues to adapt to new challenges, it remains a testament to the enduring value of medical service in the defense of the nation and the promotion of global health.

Choosing Not to Know

Why We Avoid Truths That Make Us Uncomfortable

One afternoon during the COVID lockdown I was scrolling through online news sites looking for something to read. I realized I was intentionally bypassing sites I knew I would disagree with. This surprised me because I have always been a proponent of critical thinking. Here I was practicing its antithesis— willful ignorance—intentionally avoiding evidence that contradicts my beliefs or preferences.

This behavior may seem irrational, yet it persists across all aspects of life, from personal relationships to religious beliefs to political ideologies. Understanding why we cling to falsehoods, what value we derive from this behavior, and how we can counter it is essential for fostering open-mindedness and informed decision-making.

We often assume that willful ignorance is something that affects “them”—the people with whom we disagree. Anyone can fall victim to willful ignorance, even you and me.

When we encounter evidence that contradicts our beliefs, we experience cognitive dissonance—a state of mental discomfort caused by holding two conflicting ideas simultaneously. To resolve this discomfort, we often reject new evidence rather than altering our existing worldview.

We tend to seek out and interpret information in ways that confirm our pre-existing beliefs while ignoring or dismissing evidence to the contrary. This conformation bias reinforces our opinions and shields us from uncomfortable truths.

Our beliefs are often tied to our social identity. Having our beliefs challenged can feel like an attack on our sense of self or on our group affiliations. Maintaining allegiance to a shared belief—whether religious, political, or cultural—can feel more important than factual accuracy.

Contradictory evidence can create fear and uncertainty, especially if it undermines our understanding of the world. Clinging to familiar falsehoods can provide us a sense of security and predictability.

We invest time, energy, and emotions into our beliefs. Admitting we were wrong may feel like a personal failure or a waste of effort, making it easier to reject new information than to reconsider long-held positions.

Despite its drawbacks, willful ignorance offers psychological and social benefits that make it appealing. Ignoring uncomfortable truths can protect us against guilt, shame, or fear, while providing a sense of inner peace and emotional comfort. We may attempt to maintain our sense of self and group identification by avoiding information that threatens our worldview. Engaging with complex or contradictory information requires mental effort. Ignoring it simplifies decision-making, reducing cognitive load. Aligning with a group’s shared beliefs—regardless of their accuracy—fosters social cohesion and acceptance.

While anyone can fall into willful ignorance, certain factors may make some groups more prone to it. Studies show that individuals across the political spectrum exhibit willful ignorance, though the issues they ignore vary. For example, conservatives may deny climate change, while progressives may overlook the economic costs of policies they favor. Groups that emphasize doctrinal adherence may be more resistant to evidence that challenges theological teachings. Older adults may resist evidence that challenges long-held beliefs. However, younger individuals can also exhibit willful ignorance, particularly in social media echo chambers.

We are more likely to reconsider our beliefs in an environment where we feel we have been heard and understood rather than attacked and ridiculed. Constructive dialogue, rather than confrontation, opens the door to change. Facts alone often fail to persuade. Framing evidence within emotionally resonant stories can make it more effective. Presenting new information in small, digestible portions helps reduce cognitive dissonance and makes new ideas less threatening. We are more likely to accept information from sources we trust, particularly those who share our cultural or ideological background.

Convincing someone that their beliefs are counterproductive requires tact and patience. But, before trying to change others, we must first examine our own beliefs to ensure we are not guilty of the same behavior. Self-examination is the first step in addressing willful ignorance.

Willful ignorance thrives in environments of fear, division, and mistrust. Countering it requires empathy, compassion, and truth. If we engage with others in a spirit of understanding rather than confrontation, we have a better chance of bridging divides and creating meaningful change.

The journey is challenging, but the rewards—for both individuals and society—will be worth the effort.

Don’t Forget Climate Change

By John Turley

On March 18, 2025

In Commentary, Politics

It Affects Us All

Climate change, one of the most critical challenges facing humanity in the 21st century, seems to be forgotten in all the controversy surrounding DOGE. Regardless of everything else going on, we can’t ignore climate change because it affects global temperatures, weather patterns, ecosystems, and economies. The overwhelming scientific consensus is that human activities—primarily the burning of fossil fuels—are driving climate change.

The existence of climate change and the impact of human activity, like any other field of science, includes areas of disagreement among researchers. One of the principal areas of disagreement is about the sensitivity of the climate to the increase in CO2 production and the rate at which global warming will occur. There’s also discussion about how effective climate models may be with some arguing that the models may either overestimate or underestimate certain effects. A significant area of disagreement is over what is known as the “tipping points”. This is a debate about when or if certain events such as ice sheet collapse, permafrost thaw or ocean circulation changes might occur. Some argue these events could trigger rapid self-reinforcing climate shifts while others believe changes will be more gradual. Even with this disagreement there is broad acceptance that climate change has increased the frequency and intensity of heat waves, heavy rain and extreme weather.

As intense as some of these scientific debates maybe, they pale in significance beside the political debates being generated around climate change.

When the possibility of climate change was first recognized in the 1970s and 1980s there was bipartisan support to address possible remediation of long-term impacts. Republican President Richard Nixon signed landmark environmental laws including the Clean Air Act.

During the 1990s climate change became more polarized. President George H. W. Bush begin to frame climate change policy as an economic threat. George W. Bush rejected the Kyoto Protocol to avoid “economic hindrance”.

By 2008 the partisan divide had significantly increased. Republicans increasingly dismissed climate risks while Democrats amplified the urgency of taking action. By 2023, 78% of Democrats prioritized climate policy, but only 21% of Republicans viewed climate action as urgent despite increasing climate risks in some GOP dominated states such as Florida and Texas.

The partisan gap expanded as conservative science skeptics continued to raise issues about rates of change, economic impacts and potential solutions. These conservatives tend to view climate policies as government overreach, while progressives hold the position that the government led initiatives are essential to combat environmental threats.

As they have in many other issues, the media have lined up into conservative and progressive camps. The conservative leaning media downplays climate risks while the liberal leaning media emphasizes the danger and need for urgent action. As with many other things this leads to a “echo chamber” effect simply reinforcing political beliefs without adding anything new of significance to the debate.

The Trump administration has signaled its desire to undo many of the climate change initiatives put in place by Democratic administrations. On January 20, 2025, President Trump signed Executive Order 14162 directing the immediate withdrawal of the United States from the Paris Climate Agreements and related international climate commitments. He has declared a “National Energy Emergency” to accelerate fossil fuel development and ease restrictions on the construction of new oil and gas projects. As part of this effort, he has weakened environmental reviews. This is expected to significantly increase fossil fuel consumption and associated greenhouse gas emissions. The Trump administration has begun the rollback of environmental regulations. Lobbyists for the oil, gas and chemical industries have been appointed to the Environmental Protection Agency to reverse climate regulations and pollution controls.

The administration is withdrawing funding for clean energy initiatives including those aimed at reducing carbon emissions and promoting renewable energy resources. The administration has initiated a review of the “legality and continued applicability” of the EPA’s endangerment finding which is the basis of most federal regulations on greenhouse gas. The administration rolled back regulations limiting methane emissions from oil and gas operations. The definition of “waters of the United States” under the Clean Water Act was narrowed, potentially allowing increased pollution in streams and wetlands.

We can expect increases in severe weather because of Trump’s environmental policies. These policy decisions collectively hinder efforts to mitigate climate change, potentially leading to increased greenhouse emissions and global warming. Reduction in funding for climate change research and the rollback of environmental regulations will have long term adverse effects on both domestic and global environmental health.

Significant budget cuts and layoffs within agencies like the National Oceanic and Atmospheric Administration (NOAA) could impair the ability to forecast and respond to severe weather events. For instance, the reduction of meteorologists and environmental scientists may hinder critical forecasting services, affecting public safety during events like hurricanes, tornados and floods.

The U.S. withdrawal from international climate initiatives, such as the Loss and Damage Fund, reduces financial support for developing countries dealing with climate-induced disasters. This could lead to inadequate infrastructure and preparedness in vulnerable regions, potentially increasing the severity of weather-related impacts.

While it is challenging to attribute specific future weather events to current policy changes directly, the administration’s environmental policies will likely contribute to conditions that favor more frequent and intense extreme weather events. The combination of increased greenhouse gas emissions together with weakened environmental regulations, reduced climate research capabilities, and diminished global climate cooperation collectively enhance the likelihood and impact of severe weather phenomena. This damage to our environment needs to be prevented! Once it occurs it will be difficult to ever reverse and our children and grandchildren will suffer as a result.
