What proof do we have that CO2 is a greenhouse gas? How do we know it has caused global warming?

What proof do we have that CO2 is a greenhouse gas? How do we know it has caused global warming?

i. None. ii. We know that it hasn’t.

All of the claims that CO2 is a “greenhouse gas” come from the leftist-run U.N. IPCC octopus, which for decades has been pushing a fake physics hoax in order to frame CO2 emissions as evil in order to get the fossil fuel industry shut down as part of their master plan to foist global Marxism on a freezing or boiling, starving, defenseless world, and have the EU, Britain, the Pope, and most recently Pres. Biden and the Democratic Party in their pocket, who are attempting it to force it on the American people without allowing them to vote on it first.

The CO2 warming hoax started out as a weapon created by global Marxists and leftist environmentalists to destroy the fossil fuel industry that underpins capitalism, and grew to incorporate leftist billionaires in a master plan to create a New World Order called the Great Reset. By the time it dies it will have done unimaginable evil.

Cheating in Science Is Nothing New: Is Climate Fraud the Most Blatant Example?

The hoax is that atmospheric CO2 can rewarm Earth’s surface with its own heat by sending surface IR back down, and even raise the temperature higher than ever before in pre-industrial times. Recently they saw people waking up so they changed the goalposts by claiming that CO2 blocks surface infrared from escaping to space, which magically increases surface temperatures without any physical mechanism, because physics requires non-solar heat radiation to rain down on the surface from the sky, and warming the upper atmosphere doesn’t warm the surface where we live. Either way, here is the hoax in simplest terms, straight from IPCC-run Wikipedia:

“The Earth's surface warms as a direct consequence of increased atmospheric CO2.” - Climate Sensitivity - Wikipedia article

Their hoax usually starts out by referring to obsolete 19th century physics experiments that found that a tube of pure CO2 gas reaches a little higher temperature than a tube of plain air when roasted by an infrared heater. This is a worthless experiment because it confuses heating via radiation with heating via heat conduction on the glass tube walls.

All gases can gain heat via conduction, but gaining heat via radiation is different. CO2 has a lower heat capacity than pure air, and it takes less Joules of energy to raise its temperature by 1 degree C, so no wonder it gets a little hotter, but the experiment doesn’t limit way the Joules are supplied by limiting the infrared source to the wavelengths that CO2 can absorb/emit, which are a small interval around 15 microns. Funny, but lab experiments only show that the pure CO2 tube has a 2C higher temperature than plain air, while the IPCC claims that even raising atmospheric CO2 levels from the current 0.04% (400 ppm) to 0.08% (800 ppm) will raise it way higher, threatening climate Armageddon.

No surprise that they never show a lab experiment where a tube of water and dirt is placed next to the pure CO2 tube to see if CO2’s infrared radiation raises its temperature, because it won’t, and that would give the game away. - Greenhouse Gas? The Two Bottles Experiment Explained | Principia Scientific Intl.

Planck’s Black Body Radiation Law was announced in 1900, way after the original experiments supposedly demonstrated the greenhouse effect. It covers all cases in radiative physics, and is universally accepted.

Planck's Law - Wikipedia

The Sun and the Earth’s surface are Planck black bodies that absorb and emit radiation (photons) at all wavelengths, but after the absorption raises the object’s temperature, the emission is along a fixed power-wavelength curve based solely on that temperature. The higher the temperature of the object, the shorter the wavelength of the peak power, where the most photons are emitted, giving the object a radiation temperature to match its internal temperature, so that it can’t violate the Second Law of Thermodynamics that prohibits a colder body from raising the temperature of a higher body by any means including radiation. If you put a hotter black body near a colder one, it will slowly increase in temperature, with its black body radiation curves progressing through all the temperatures as the peak power wavelength shortens. But the temperatures will eventually equalize, and there will be no net heating. That atmospheric CO2 thermal radiation is exempt from the Second Law is one of the IPCC’s big lies that they regularly push on the scientifically illiterate populace.

Atmospheric CO2 isn’t a black body because no gas is. Gases don’t absorb or emit radiation unless they’re polar. CO2 gas only absorbs and emits radiation in a small band around 15 microns, which has a Planck black body radiation temperature of -80C, colder than dry ice (frozen CO2).

Too bad for the IPCC lie machine, modern physics is clear that CO2 can’t melt an ice cube with its 15 micron -80C radiation that’s way too frigid to have any effect. In other words, 15 micron photons can’t raise the temperature of a molecule absorbing them higher than -80C. The Earth’s surface temperature range caused by solar radiation is -50C to +50C, and atmospheric CO2 can only absorb or emit radiation at or near 15 microns, that is, -80C, thus it can’t even interfere with Earth’s real climate system driven by the Sun and cooled by the atmosphere, which is 99.96% non-CO2. CO2 is of use only as the driver of plant photosynthesis to green the Earth and feed the teeming billions.

CO2 infrared absorption - Climate Auditor

Atmospheric CO2 supplies zero heat to the climate via radiation, zilcho, nada, either on the surface or in the sky, because it can only absorb and emit radiation at a wavelength of 15 microns, which has a Planck radiation temperature of -80C, colder than dry ice (-78.5C). The IPCC likes to breed confusion by letting its dupes believe that just because the Earth’s surface is a black body that absorbs and emits radiation at all wavelengths, so does atmospheric CO2, when the truth is that it can only absorb photons one at a time by catching them in its electrons by forming an electric dipole, after which it has to reemit the photon to free it to absorb a new one, leaving the molecule's temperature unchanged. The net power is miniscule compared even to an iron rod chilled to -80C, causing most of its Planck black body photons to be at 15 microns.

I’m not framing the IPCC unless they’re framing themselves. Here’s one of their so-called peer (really pal) reviewed papers pushing the CO2 warming hoax, complete with diagrams of CO2’s electric dipole bending and stretching modes and the wavelengths of photons they capture, oblivious to the Planck radiation temperatures, going on to utter one IPCC lie after another to hand-wave the hoax through. And I guess most scientists fall for it all without question. I wish they could listen to me just once.

Carbon Dioxide Absorption in the Near Infrared

Here’s a quote from another a major U.S. university, spouting ridiculous nonsense dressed up as matter-of-fact science with a haughty attitude as if they’re trying to explain it to a 5th grader:

“Human-driven climate change remains a controversial topic, but some scientific facts about it are beyond controversy. At the recent Comer Abrupt Climate Change Conference, three scientists stressed the importance of understanding one such fact: the proven greenhouse effects of carbon dioxide (CO2) collecting in the Earth’s atmosphere. The greenhouse effect means that CO2, emitted in large quantities by burning fossil fuels, traps heat and is raising temperature across the globe.” -

The Fundamental Physics of Carbon Dioxide

Traps heat? How? With 15 micron photon capture and reemission? Yes, trace CO2 (0.04%) in the atmosphere at the surface absorbs surface heat by contact, making it buoyant and causing it to rise toward space, cooling the surface not warming it. But once up high, CO2 can only absorb and reemit 15 micron photons, which can’t melt an ice cube. What ridiculous nonsense.

Here’s another nonsense article from the IPCC lie machine, this time from a U.S. govt. Web site run by IPCC propagandists:

“Carbon dioxide is a greenhouse gas: a gas that absorbs and radiates heat. Warmed by sunlight, Earth’s land and ocean surfaces continuously radiate thermal infrared energy (heat). Unlike oxygen or nitrogen (which make up most of our atmosphere), greenhouse gases absorb that heat and release it gradually over time, like bricks in a fireplace after the fire goes out. Without this natural greenhouse effect, Earth’s average annual temperature would be below freezing instead of close to 60°F. But increases in greenhouse gases have tipped the Earth's energy budget out of balance, trapping additional heat and raising Earth's average temperature.”

“Carbon dioxide is the most important of Earth’s long-lived greenhouse gases. It absorbs less heat per molecule than the greenhouse gases methane or nitrous oxide, but it’s more abundant, and it stays in the atmosphere much longer. Increases in atmospheric carbon dioxide are responsible for about two-thirds of the total energy imbalance that is causing Earth's temperature to rise.” - Climate Change: Atmospheric Carbon Dioxide

Duh, atmospheric CO2 molecules reradiate 15 microns almost immediately after absorbing them, not “gradually over time like bricks in a fireplace”. The howler that the Earth has a “natural greenhouse effect” from atmospheric CO2 that keeps it from freezing is another one of the big lies of the IPCC, meant to make discussion of the 15 micron problem seem needless. When you analyze this claim, it falls apart like a cheap suit, like all the other IPCC lies, such as a mystical “energy balance” that too much CO2 is upsetting.

How much does the Sun contribute to global warming?

Speaking of lies, one of the IPCC’s biggest whoppers is to turn the Stefan-Boltzmann Law inside-out to justify the dinky amount of atmospheric CO2 15 micron radiation as raising Earth surface temperatures.

Stefan-Boltzmann Law - Wikipedia

What this law says is that the total power underneath the Planck Black Body Radiation curve is proportional to T to the 4th power. But the object only attained the temperature T after another black body as hot or hotter radiated its energy into it. How low can the IPCC go when it claims that the tail wags the dog, and so many watts per square meter of CO2’s 15 micron radiation automatically raises the black body’s temperature by the 4th root of total power.

Here's a typical one for discussion:

"What is the process of Greenhouse Gas absorption? According to the Intergovernmental Panel on Climate Change (IPCC, Fourth Assessment Report, 2004) whom incidentally won the 2007 Nobel Peace Prize, to balance the absorbed incoming solar energy, the Earth must, on average, radiate the same amount of energy back to space. However, since the Earth is much colder than the Sun, it radiates at much longer wavelengths, primarily in the infrared part of the spectrum. Much of this thermal radiation emitted by the land and ocean is absorbed by the atmosphere, including clouds, and reradiated back to Earth, thus warming it. This is called the greenhouse effect. Since part of this re-radiation is back towards the surface, energy is transferred to the surface and the lower atmosphere. As a result, the average surface temperature is higher than it would be if direct heating by solar radiation were the only warming mechanism." - Greenhouse Gas (GHG): The Runaway Effect-Earth’s Surface Heat Out of Balance, by Kali R. McMillan, Jan. 28, 2012.

Let's start with the lie that "the Earth must, on average, radiate the same amount of enery back to space" as it received. That would only be true if it were some kind of perfect mirror. It actually burns a bunch of energy to run the winds and storms of the weather. If they lie about this, you can't believe anything they say.

Here's the Simple Simon explanation of the fake greenhouse effect, as explained by one of the U.N. IPCC's hydra heads.

"Let me explain the background here. The earth would continue to warm from sunlight and its own geothermal heat sources if it were not for its ability to radiate that heat back into space. This is the principle of thermal equilibrium. A body’s temperature exposed to a heat source continues to rise until that body can somehow rid itself of the heat essentially at the same rate that it absorbs it. The earth’s worldwide average temperature is regulated by a number of factors including its ability to radiate this excess heat back into space. This radiation is largely in the infrared region of the spectrum. We can’t see it but you certainly can feel it coming off a hot sidewalk in the summer time. I’m sure everyone has noticed that that in this desert environment it cools off dramatically at night unless… it happens to be cloudy. Now it turns out that by some perverse twist of mothernature, carbon dioxide, methane and water vapor among others absorb radiation in about the same radiation bands that the earth uses to get rid of it. (A full explanation here requires some discourse into atmospheric absorption bands and black body radiation which may cause some unwary readers to lapse into a coma.) The earth’s atmosphere acts as a blanket of sorts and it follows indisputably from the physics associated with transmission of radiation through the atmosphere that the higher the concentration of these gases in the atmosphere, the more this radiation gets absorbed and the higher the resultant atmospheric temperature unless... there are mitigating mechanisms." - A Commentary and Brief Tutorial on Climate Change, Joseph S. Accetta, PhD

At least give this dude some credit for cutting straight to the chase with the following global Marxist agitprop wrapper:

"As most everyone is aware, there is considerable controversy over climate change. It has become a political football of course like many other issues. What is particularly perplexing is that denial or acknowledgement either way seems to mostly follow from social media or some other politically connected source. Why a significant number of people don’t believe that the climate is changing is some sort of sociopolitical phenomena, not based on scientific data and directly tied to rampant political polarization and tribalism. To the deny-ers, [sic] the idea of climate change seems to be irrationally characterized as some sort of conspiracy, to what end heaven only knows... The real issue is not that it is happening but what to do about it!"

To what end heaven only knows? He's just telling people to block out all "climate denier" publications and never even discover the M word being mentioned.

Now can I get my two cents worth in? Here's the simplest explanation of how Earth climate really works, which I wish would become a popular meme.

First, ONLY THE SUN heats the Earth's surface, and only by radiation, because it's a black body that absorbs photon radiation of all wavelengths and slowly builds up its internal energy density, which is measured by temperature. The temperature of Earth's atmosphere is not increased by solar radiation, or any radiation, because radiation can't increase the tmperature of a gas, period. Why? Because a given gas molecule either lets a photon pass by untouched, or absorbs it then soon reemits it in another direction, leaving its temperature unchanged, with no build-up of internal energy like in a black body, which can only be a solid or a liquid with interlocking molecular bonds that have an internal energy density.

The temperature of a black body is a measure of its internal energy density, while the temperature of a gas consisting of bouncing molecules that have no interlocking molecular bonds is a measure of their average kinetic energy, therefore the nearly universal U.N. IPCC claim that atmospheric CO2 gas traps infrared photons and increases its temperature is colossally stupid.

The atmosphere gets ALL its heat by contact with the surface, followed by conduction, causing it to become more buoyant and begin rising toward space, slowly cooling as it trades heat for work to expand against decreasing pressure, bottoming out at -60C at the top of the troposphere (bottom of the stratosphere) at about 10 km, where all weather ends. The gaseous composition of the atmosphere only determines its specific heat content, the number of joules needed to be absorbed by conduction to raise its temperature by 1C. Radiation has no function. Yes, CO2 gas has a l ower specific heat capacity than N2 or O2, meaning it takes less joules to raise its temperature by 1C, but since CO2 only comprises 0.04% (1 part in 2,500) of the atmosphere, its heating effect is miniscule, and in no case does radiation play any part, meaning that atmospheric CO2 doesn't "trap heat via radiation", which is perhaps the most despicable lie peddled by the U.N. IPCC octopus of scammers, try telling them that and demanding the money back.

Forget the global Marxist ploy of making everything about Earth climate global by pushing mathematically impossible averages along with nonsensical global numbers. All Earth weather is local, based on a zillion different surface temperatures all over the globe. There is no global Earth weather or climate. If you see your local weather remaining stable and livable year after year, cycling nicely through the four seasons, you can take the global climate crap and flush it down the commode. You're being played for money and power.

Any other attempted rationales for a greenhouse effect are pure bullshit. RIP greenhouse effect. They were really pushing the greenbacks effect. Tax moneys should be used to solve real problems, not the sick fake problem that there isn't enough Marxism.

Ever since the atmospheric CO2 concentration began rising to the current level of 420 ppm, there’s been a massive greening of the Earth, esp. in the Sahara. Greenhouse operators regularly pump in CO2 to a level of 1000–1500 ppm to maximize profits, which IPCC scientists try to pooh-pooh by dishonest experiments trying to prove that the extra food will have lower nutritional value, as if they never read a greenhouse operator manual that shows how to adjust the soil chemistry to keep nutritional value up. Each year the concentration value only goes up by 3 ppm, meaning that it would take 200 years to reach the desirable level, by which time the fossil fuels will have probably been used up and we had plenty of time to switch to nuclear power, fission or fusion. How sick to actually plan on pulling CO2 out of the air, threatening global starvation.

In every case of their multi-dimensional scam, the IPCC always peddles the punch line that it will “cost society” to implement their alleged solutions to the CO2 non-problem. That makes them the looming threat in the future, not CO2. Leave the fossil fuel industry alone and thank them for providing your happy comfortable abundant lifestyle that separates you from Victorian manure shovelers and steam engine operators.

“The Global Warming Scam has been perpetrated in order to support the Environmentalist belief that the earth is being harmed by the emission of greenhouse gases from the combustion of fossil fuels. The Intergovernmental Panel on Climate Change (IPCC) was set up to provide evidence for this belief. They have published four major Reports which are widely considered to have proved it to be true. This paper examines the evidence in detail and shows that none of the evidence presented confirms a relationship between emissions of greenhouse gases and any harmful effect on the climate. It is the result of 18 years of scrutiny and comment on IPCC Reports and of a study of the scientific literature associated with it.” - Dr. Vincent Gray, PhD chemist and IPCC Reviewer THE GLOBAL WARMING SCAM

Here’s a quote from the leading IPCC critic site:

“Before proceeding to more modern times and the POLITICALLY MOTIVATED man-made global warming hype, a few words on the IPCC. The organization was originally formed in 1988 with a defined mandate to study to what extent human activities might be changing Earth’s climate. The first Assessment Science Report (FAR) was published in 1990. I recall having been enthusiastic awaiting new information on the state of Earth’s climate. I read the many pages and learned a lot. However, getting my hands on the first Summary for Policy Makers was an anticlimax with a message drastically different from the actual Science Report.”

“During the following years the science reports still contained a lot of interesting information on Earth’s climate and the various factors affecting both weather and climate. However , the consecutive Summaries for Policy Makers seemed to escalate “climate scare-mongering” on which media was quick to develop horror stories of extreme natural catastrophes in a very near future unless CO2 emissions are curbed “immediately”. This message was further distorted by narratives from IPCC chairman Pachauri and ex-vice-president Al Gore. I could not believe that the climate science was settled!”

“The IPCC tries feverishly to prove that human emissions of CO2 has a detrimental impact on global temperatures. This requires a blind belief in computer modeling.” - The Water Planet Earth and Its Climate

Here’s an IPCC scientist getting a big stage to promote the CO2 warming hoax with its huge price tag. Who’s right? Give me a chance and study my cool essay teaching the Planck Radiation Law and working out its consequences to prove that CO2 can’t melt an ice cube.

Global Warming is a Hoax by TLW

There is No Greenhouse Effect by TLW

The Big Lie About CO2 by TLW

Postscript: All bad storms are cooling at work, not global warming.

Marxists hijack science for political gain by doing everything they can to turn it upside-down, inside-out, topsy-turvy, and ass-backwards to so screw your mind that you totally surrender your reason to them, along with your soul. The constant lies about bad storms being the work of CO2-driven global warming should win a medal from the Devil. So back to the original question, how do we know that CO2 has caused global warming, with the answer being it hasn't because of thermal physics.

Did you 'get' it yet that ONLY THE SUN heats Earth's surface? After that it's about the variety of cooling processes, including radiation, contact/conduction and convection, and evaporation. The problem is that while radiation is mostly uniform ever local areas, both upward and downward, convection and evaporation involve molecules not radiation, which because of entropy mix up in wild and unpredictable ways, creating all storms, many of which are frequently violent. But don't blame this on global warming, except in the obvious sense that the Sun causes all daily warming, and everything else is caused by attempts at cooling.

Yes, if the Sun were starting to go red giant and starting to swallow the Earth, there would be real global warming, and all Hell would break loose every day. But that's a billion years off at least, so screw that, and screw the U.N. IPCC global Marxist con artists who each year spend more of your taxpayer money gaslighting bad weather spells in different areas of the Earth as proof of long-term systematic global warming caused by Big Oil's CO2 emissions.

Talk about upside-down. They base all their sick lying climate alarmist agitprop on announcements of "global yearly surface avg. temperature" (GAT), which doesn't even exist for a variety of reasons, but they need it to make their useful idiots who will panic at predictions of non-existent runaway warning thresholds like 1.5C, which are phonier than funny money. The truth is that only if the maximum measured surface temperature over the globe goes up each year would there be real global warming, not tiny increases in statistical made-up temperatures that can be made to come out to anything they want to suit their propaganda purposes. And guess what? That number hasn't gone up since July 1913, before there was a Big Oil to frame for money and power.

The U.N. IPCC fake scientists love to ignore the elephant in the room, the oceans, which cover 71% of Earth's surface and are its real climate control knob. Each day they absorb tons of solar radiation and barely increase their temperature because of their high heat capacity. Then when some evaporates it rises until the water vapor turns to ice crystals, creating clouds, which block solar radiation from reaching the surface, after which they drop freezing precipitation, making water into Earth's air conditioner and refrigerator. Did you hear a U.N. IPCC loon claim that water vapor causes a greenhouse effect?

Back to bad winds. In the winter another phenomenon comes into play, namely, the fact that cold air is more dense than warm air, and sinks, allowing regions where hotter air rides on top of colder air, inverting the natural convection-based lapsed rate of decreasing temperature with height. That is what causes bitter fast-moving Arctic cold fronts, but that's meteorology, not global climate science, so let's stop here.
