My reply:
[[The results all indicate that carbon dioxide cannot be the driver of climate change. At best it can contribute only a small proportion to the change in global temperature since the end of the Little Ice Age. ]]
[[In some quantity, everything in the air including nitrogen and oxygen absorbs and emits black body radiation at frequencies which overlap the frequencies absorbed by CO2. In fact, the only reason why there is IR in the air is because the surface of the earth emits black body radiation in proportion to its temperature. The air then does the same thing at some level.]]
Zonk! Wrong!
This is a common misconception. Gases don't emit Planck (blackbody) radiation. Only coalesced substances (solids and liquids) do, because they have to be able to share their heat energy via molecular contact to attain a common temperature then emit heat energy through a surface in large quantities along a Planck power-wavelength curve of a characteristic shape whose peak power wavelength indicates the substance's temperature.
Gas molecules are constantly bouncing around and exchanging energy in an attempt at achieving equilibrium, but emit quantum energy only on a photon by photon basis, and everybody knows that the quantum world disappears at the macro level where Planck's Law rules. That's why the Stefan-Boltzmann Law has units of watts per square meter, not watts per cubic meter So much power is concentrated at the peak power wavelength that it characterizes the temperature to quantum precision via Wien's Displacement Law (T * wavelength = constant), which is why we can literally see temperature in an iron bar being heated in a fire, and measure temperatures with optical infrared thermometers.

The Sun is a solid body with a coalesced surface, and it emits Planck radiation at a max power temperature of 5800K (5527C) (9980F), which travels through space to Earth's atmosphere, the visual wavelengths making it through unhampered and hitting Earth's surface, heating it up to as high as 50C and causing it to try to cool down by emitting Planck radiation. Space and air don't emit Planck radiation, but air does absorb heat from Earth's surface via conduction and vent it toward space via convection, helping slow the cooling process compared to pure radiation like on the unlivable Moon, i.e., air convection moderates the temperature swings to keep Earth livable. Air can absorb radiant energy, and reemit it on a photon by photon level, but never along a Planck radiation curve consisting of a spectrum of wavelengths, so it's not going to do diddly to raise the Earth's surface temperature but only waste its pathetic photons on materials emitting far more power at each of its wavelengths.
Sunlight's visual wavelengths are .4-.8 microns (6971C to 3349C), but since Earth's surface has a heat capacity of so many K per Joule per gram (4K/J/g for water, 0.7K/J/g for silicon or sand), at the radiant strength that reaches Earth's surface, Earth's Planck radiation wavelengths are 13 microns (-50C) to 9 microns (+50C).

Too bad, CO2's is a non-player in the global warming game, because its absorption/emission wavelength of 15 microns has a Planck radiation temperature of -80C, outside of Earth's surface temperature range, hence blaming it for global warming is a pure fake physics hoax. Atmospheric CO2's -80C photons can't melt an ice cube, and anybody pushing the CO2 global warming moose hockey should have their mouth washed out with soapy ice water. Nobody seeking to understand Earth's climate should waste one second with CO2, because only the Sun heats Earth's surface, and the atmosphere only cools it, acting not like a greenhouse but a chimney along with a blanket due to its thermal inertia, i.e., slowing of heat removal compared to pure radiation. If the Sun goes cold, Earth will freeze pronto,in a few days probably, but thank you know who it keeps basting the Earth's surface like a rotisserie chicken, heating it up then allowing it to cool down over night endlessly
Real physicists (not fakey climatologist physics dropouts) like James Clerk Maxwell and Richard Feynman long ago used statistical mechanics to compute Earth's average temperature from the Sun's radiant power, Earth's gravity, and the specific heat of Earth's atmosphere, with CO2 or any gaseous radiation not included:

This article by a biologist full of side issue data is nice if you have the time to waste, but the real question is why do we want to become unpaid climatologists when all we want to know is what effect if any CO2 has on global temperatures, and we now have the answer: ZILCHO!
So don't kowtow to the CO2 hoaxers with wishy-washy statements about CO2 having a "mild" effect on temperatures. -80C isn't even heat. You can't mention CO2 and heat in the same breath without talking nonsense. How many times do I have to beat this dead horse in the pages of P-S, which is supposed to have an educated readership?
Here's my killer essay for the masses that's waking people up and causing the leftist-run U.N. IPCC to be laughed into oblivion. If IPCC used even one millionth of its great wealth and power to distribute it, er, forget it, they're in it for the money.

How many millions of tons of CO2 are being pumped into the atmosphere annually? Just imagine the cost! You must pay up!
I don’t need to imagine it. It’s ZERO. CO2’s absorption/emission wavelength of 15 microns is composed of -80C photons, which are way outside the range of Earth’s surface temperatures (-50C to +50C). Every photon has an energy that’s inversely proportional to its wavelength. When it is absorbed by a material, it imparts that energy to the material as kinetic energy, which is also known as temperature. 15 micron photons can’t raise the temperature of a material higher than -80C, no matter their concentration. In contrast, photons from the Sun are at 5800K (5500C). Usually the Earth’s surface has so many cooling processes that sunlight can’t raise the temperature higher than +50C, but a large field of mirrors collecting sunlight and concentrating it to a single point might reach a temperature near 5500C. -80C is about the temperature of dry ice, and no matter how big a field of dry ice, it can’t raise the temperature of anything above -80C.
So CO2 emissions are no threat to global temperatures. Cold isn’t heat. Cold can’t heat anything. Even if the current atmospheric CO2 concentration of 0.04% were 0.4% or 4% it can’t cause global heating. If a new ice age comes, hold onto your dry ice. Only zany leftists can turn cold hot and hot cold to get their hands on cold cash.
It’s really that simple. Tell your friends about my killer essay disproving CO2 global warming with pure physics:
