[Shocking fact] The Edo period was 2 degrees colder than today! The truth that the greenhouse effect of 90% is not CO2

🏯 Prologue: Was the Edo period colder than it is now?

The hot days continue, but are you all taking measures to prevent heatstroke?

By the way, do you know this story? About 400 years ago, during the Edo period, Japan was much colder than it is today.The Sumida River was frozen and we could walk across it.There is a record that says this.

Lake Biwa also froze over, and crops frequently suffered from crop failures.

This period is called the "Little Ice Age," and the Earth was 1-2 degrees cooler than it is today..

Edoites lived their lives battling the cold more than we can imagine..

📊 Earth's Climate History

• Medieval Warm Period(1000 years ago): Warmer than or equal to the present
• Little Ice Age(400 years ago): 1-2 degrees cooler than today
• the current: An era in which global warming is being discussed

Interestingly, in the Middle Ages (about 1000 years ago)Medieval Warm Period" and it was as warm or even warmer than it is now.

It was actually thanks to this warm period that the Vikings were able to settle in Greenland..

This means that the Earth's climate has been changing for a long time.This is the natural appearance.

Knowing this history, doesn't it help us see the current climate change debate from a slightly different angle?

🌡️ Chapter 1: Surprising Truth! The main cause of the greenhouse effect is actually water vapor

The breakdown of the greenhouse effect that textbooks don't teach

When we think of global warming, we think of CO2 (carbon dioxide).⁉

But wait a minute. If you take a closer look at the actual greenhouse effect, you'll find some surprising facts!

🔍 Breakdown of the greenhouse effect

Water vapor: Approximately 90% or more

CO2: approx. 7%

What do you think when you look at these numbers? Rather than CO2, which we treat as the villain, the clouds and steam that we see every day are actually the main players in the greenhouse effect..

Does steam from the bath have a greenhouse effect?

Think about it! The steam rising from a bath, the steam from a kettle, the moisture from drying laundry, and even our breath contains water vapor.

Of course, that doesn't mean you shouldn't take a bath (laughs).

Water vapor is part of the natural cycle and returns to the earth as rain.

just,It's not as simple as "CO2 is the only bad guy"So, it's something to keep in the back of your mind.

It's a completely different story depending on the altitude

This is also an interesting story,The impact of CO2 varies greatly depending on the location.That's it.

✈️ Over 10,000 meters above the ground

There is almost no water vapor, so CO2 is the main

🏠 Near ground level

There is plenty of water vapor, so CO2 plays a limited role‼

The world above the clouds that we see when we fly is governed by completely different rules than the world on the ground where we live.

🏙️ Chapter 2: The real reason cities are getting hotter

Temperature measurements in Tokyo are actually done in the middle of a city full of buildings

Where do you think the temperature in Tokyo is measured?

The measurements are taken at the Japan Meteorological Agency headquarters in Otemachi, so please take a look around you.

High-rise buildings, asphalt, car exhaust fumes, air conditioner outdoor units...

This is purely "Global temperature"Can you say that?

The power of the heat island phenomenon is incredible

In cities, artificial heat can raise temperatures by 2-3 degrees..

This is a completely different physical phenomenon from the greenhouse effect, simply a result of "there is a lot of hot stuff.".

🔥 Causes of heat islands

• The heat storage effect of asphalt
• Radiant heat from buildings
• Exhaust heat from air conditioner outdoor units
• Car exhaust
• Decrease in green space

Try touching the asphalt on a summer night! It stores solar heat during the day and releases it into the night.‼

This is happening all over the city.

Are temperatures rising on remote islands?

However, when we look at data from remote islands and mountainous areas that are not affected by urbanization,There is no clear temperature riseIn many cases.

Looking at the temperature data for Hachijojima, there is no evidence of a rapid upward trend like in urban areas.

This means that what we think of as the "global average temperature rise" is actually"Rising average temperatures in cities"Doesn't this suggest that it might be?

🔄 Chapter 3: Why "Global Warming" Has Changed to "Climate Change"

Strange events that happened in the 2000s

In fact, in the first decade of the 21st century,The rise in the average global temperature has stoppedThat's it.

Scientists were also puzzled and began discussing this phenomenon, calling it a "hiatus."

From that time on, the term "climate change" began to be used in preference to "global warming."

Is this a coincidence?

📅 Terminology Evolution

• 1990s: "Global warming" is mainstream
• Early 2000s: Temperature rise stagnation
• Late 2000s'Climate change' goes mainstream

First of all, the climate changes

If you think about it, the climate is inherently changeable.

🌀 Types of climate change

• Seasonal changes in spring, summer, autumn and winter
• Differences in weather from year to year
• Changes over decades
• Changes over hundreds of years, like those in the Edo period

Climate is variableBut when you hear that things are "fluctuating," don't you feel like, "Well, of course that's true"?

⚠️ Chapter 4: The reality of "hypocritical policies" disguised as eco-friendly policies

Now, here comes the crux of the matter.

The "inconvenient truth" about solar panels

Solar power generation is often thought of as clean energy.

but,CO2 emissions when making panelsAre you taking this into account?

🏭 CO2 emissions from the solar panel manufacturing process

1. Silicon Refining: Melting at high temperatures → large amounts of electricity consumed
2. Panel manufacturing: Mass production in factories
3. Installation: Fuel for heavy machinery and trucks
4. Regular maintenance
5. Disposal after 20 years: Treatment of hazardous substances

Including all of these,It will take more than 10 years for the panels to "pay for themselves"There are also estimates that this will take

Since the lifespan is about 20 to 25 years,Is it really eco-friendly?"Don't you wonder?

🌳 More serious issues

Deforestation to build large-scale solar power plants.

Cutting down precious forests that absorb CO2 and installing panels is putting the cart before the horse.

Examining the "pretty words" of EVs

The same goes for electric cars. While they do not emit exhaust gases while driving,Have you forgotten about making batteries?

🔋 Materials needed for EV batteries

• lithium: Mining by drying up salt lakes in South America
• cobalt: Child labor issues in African mines
• nickel: Massive soil contamination during mining

Mining these minerals requires enormous amounts of energy and results in large amounts of CO2 emissions..

And the biggest problem is,"Where is that electricity produced?"That is it.

What if you were to charge your EV with electricity generated by a coal-fired power plant?

Energy efficiency deteriorates as the process progresses from thermal power plant to transmission line to charger to battery to motor..

As a result, gasoline-powered vehicles with better fuel economy may emit less CO2..

A "good deal" between politicians and businessmen

Why are such contradictory policies being pursued? The answer is simple:Because it makes moneyis.

💰 Solar power generation interest structure

• Guaranteed profits from the feed-in tariff system
• Market expansion through installation subsidies
• Rental income to landowners

💰 Economic Benefits of Promoting EVs

• Creating new industries
• Stimulating the market through subsidies

Patent business in related technologies and moreCarbon Credit TradingThat is,Buying and selling CO2 reduction rightsA new business called "" has even been born.

When I look at these,"For economic gain" rather than "for the global environment"Don't you think this aspect is stronger?

Hypocrisy in the name of "greenwashing"

Companies and governmentsEnvironmentally friendly" while creating the image that " is increasing the environmental burden.Greenwashing" he says.

Anything is good if it has the keyword "eco"It is also important to question this trend..

🇯🇵 Chapter 5: Japan's proud "genuine environmental technology"

Here's a technique worth learning

On the other hand, Japan has truly environmentally friendly technologies.‼

The thermal power plant in Tsurumi, Kanagawa Prefecture, is attracting attention from around the world for its efficiency and cleanliness.

Practical and effective technology, not just for showThis is a typical example of.

🔧 Japan's excellent environmental technology

• Energy-saving technology: Reduce energy consumption at the same level of living
• Highly efficient engine: Improved fuel efficiency leads to substantial CO2 reduction
• waste treatment technology: Achieving both recycling and proper disposal
• High-efficiency thermal power generation: World's highest level of power generation efficiency

These aren't flashy, butPractical technology that reliably reduces environmental impactis.

🏯 Epilogue: Learning from the wisdom of the Edo period

Making decisions that are not influenced by politics or business

People in the Edo period faced the severe environmental changes of the Little Ice Age.They overcame the situation not through political slogans or vested interests, but through practical wisdom and technology..

Perhaps we today need a similar attitude.

What is true environmental protection?

✅ 5 points for true environmental protection

• ✅ Decisions based on scientific facts, not emotions
• ✅ Comprehensive evaluation from manufacturing to disposal
• ✅ Calm analysis uninfluenced by vested interests
• ✅ Investing in practical and effective technology
• ✅ Examining the contradictions hidden in the beautiful name "eco"

Final Thoughts: Be a Smart Consumer

Instead of being swayed by the catchphrase "environmentally friendly,"The habit of questioning, "Is that really true?"Would you like to wear it?

Just as people in the Edo period used their wisdom and ingenuity to overcome the cold, we too canMaking choices that are truly beneficial to the global environment, without being swayed by political motives or economic interestsI would like to continue doing this.

Discover the truth behind the word "eco"Environmental policies that can be explained to children with pridePerhaps it is the responsibility of adults to seek out.

The next time you see an advertisement for an eco-car, ask yourself, "How much CO2 was emitted to make that battery?" I'm sure the world will look different to you.
