The chief culprit in global warming is our planet's canopy of H2O. Next to all other airborne substances, that's 96% already here, and only a small amount of the other molecules come from anthropogenic sources.Geez, Toadthepatsy, you posted the exact same thing in your post #58 and I answered you in post #62. Are you so completely braindead and forgetful that you can't even remember what you just posted the day before? Obviously, the answer is yes.
There was no proof of anthropogenic global warming in post #62. Try again?
OK. I'll give you a short introduction to the topic and then quote some climate scientists.
The Sun heats the Earth and the Earth ordinarily radiates enough of this heat energy back into outer space to stay in thermal equilibrium. Direct measurements show that the level of CO2 in the Earth's atmosphere has increased by over 40% in the last 150 years. Isotopic analysis shows that the extra CO2 is coming from the burning of fossil fuels. The laws of physics and numerous scientific studies and experiments have shown that CO2 is a powerful greenhouse gas that has the quality of absorbing and re-radiating the infrared radiation coming from the Earth's surface, thus keeping more of the sun's energy trapped in the Earth's atmosphere rather than being radiated away into space.
"One way of measuring the effect of CO2 is by using satellites to compare how much energy is arriving from the sun, and how much is leaving the Earth. What scientists have seen over the last few decades is a gradual decrease in the amount of energy being re-radiated back into space. In the same period, the amount of energy arriving from the sun has not changed very much at all. This is the first piece of evidence: more energy is remaining in the atmosphere. The final piece of evidence is ‘the smoking gun’, the proof that CO2 is causing the increases in temperature. CO2 traps energy at very specific wavelengths, while other greenhouse gases trap different wavelengths. In physics, these wavelengths can be measured using a technique called spectroscopy. Here’s an example:

The graph shows different wavelengths of energy, measured at the Earth’s surface. Among the spikes you can see energy being radiated back to Earth by ozone (O3), methane (CH4), and nitrous oxide (N20). But the spike for CO2 on the left dwarfs all the other greenhouse gases, and tells us something very important: most of the energy being trapped in the atmosphere corresponds exactly to the wavelength of energy captured by CO2. The investigation by science builds up empirical evidence that proves, step by step, that man-made carbon dioxide is causing the Earth to warm up."

What you showed was basically, a gross omission of the elephant sitting in the living room.
It's kind of like omitting a thousand years' worth of selected climate data to prove a crisis which does not in fact exist for the sole purpose of procuring a foundation grant for future employment. One day, someone will notice the factual shell game.
