How can you say it any better than that? Muh Global Warming was nothing but a conspiracy to implement the largest transfer of wealth from the poor to the rich that this planet has ever seen.

With one exception:
Photons must be at the same wavelength that this vibration can occur; CO2 is structured with three atoms in a row, having the carbon atom in the middle. This structure allows several modes of vibration, which increases the wavelengths that may be absorbed.
CO2, being linear, has 3N-5 vibrational modes, with N representing the number of atoms. So 3*3-5=4 vibrational modes. Perhaps you consider 4 to be 'several.' Of those 4 modes, 2 have equal energies, which means actually only 3 energy levels can cause vibration. Carbon dioxide thus absorbs 3 narrow spectra, centered at 2.7, 4.3,and 15 um. Carbon dioxide can only absorb energies corresponding to these wavelengths.
Of the three, only the 15 um wavelength lies well within the range of blackbody radiation emitted by the earth. So only that small fraction of the energy emitted via radiation, one might say the minute subfraction of it, is capable of absorption by carbon dioxide.
Water vapor absorbs a very wide range of wavelengths, mostly due to the fact that water can exist as H2O, H3O+ OH-, and several other variants due to hydrogen bonding. Each variant has its own set of vibrational modes, and these sum up to cover a wide range of the emitted blackbody radiation. That's why water vapor is a much stronger greenhouse gas than carbon dioxide could ever dream of being.
Oxygen/ozone as well has one vibrational mode in the IR spectrum, at around 11 um, but to be honest it is even narrower than carbon dioxide and is thus just as irrelevant to the overall atmospheric absorption.
There are other reasons why carbon dioxide cannot be responsible for the kind of warming that we are supposedly experiencing. This is a good page that tries to put the technical reasons into a more understandable form, for anyone interested.

Contrary to superstition, the numbers do not lie:

Arent we all supposed to be dead from a massive hole in the ozone by now?
This shi is comical.
The ozone hole bs was the first screw job.
What about cigarettes?
I've been smoking all day long and haven't even got any cancer!
What kind of screw job was that?
'Several' is greater than two, but not many. Three fits the bill.
Water vapor needs heat to exist in considerable quantities in the atmosphere.
We return then to the whole chicken and the problem, then - where the Earth receives enough energy from the Sun to be a mere 255 Kelvin... yet the surface continues to be warm enough to have water vapor in the atmosphere.
Why would such a condition persist perpetually?

Ok, I will give you that you believe it is a hoax. Everyone is entitled to their opinion. Now lets put this into perspective:
You believe that such is a hoax, now would you go out and ask to build a sea wall to protect your property and as a reason list the very thing that you are saying is a hoax for such?
That is exactly what Trump has done. He says that global warming is a hoax, yet on the application for a sea wall to protect a few of his properties, under the reason he stated global warming.
The point being one can not have it both ways. If they say it is a hoax, then they can not use it to get what they want.
