Done and Done! Let's talk. There is a body of evidence that correlates CO2 to Temperature. Where I think this falls down is the causality. There is evidence that CO2 is caused by higher temperatures, rather than is the cause of them. We see lags of a thousand years in ice core samples, where temperature goes up, and 500 to 1000 years later, CO2 goes up. This is waved away as "due to solar variability", but when solar variability is used by non AGW proponents, they are ridiculed. This is obviously cherry picking of data.

This is a common misconception, so maybe it warrants explanation. Imagine there are two large reservoirs, connected via a narrow pipe. One is CO2. Another is Temperature. The pipe represents feedback mechanism, when one becomes higher, that also causes the other to go up. (Obviously the real Earth is much more complicated, but you get the idea.) Now imagine that the Temperature lake slowly gets more water. (Say, the sun becomes slightly brighter, or a continent drift away, reducing the amount of glaciers reflecting sunlight.) As the temperature goes up, CO2 starts to follow, lagging behind. Which also makes the temperature goes up even further, but not as much as the initial change. Eventually it stabilizes. (Obviously, if the feedback coefficient is >1.0, we'll be Venus now. Thank god.) Now imagine someone suddenly dumps a lot of water in the CO2 lake, causing its level to jump up instantly. What do you think will happen? > ...when solar variability is used by non AGW proponents, they are ridiculed. Well, yeah, duh, when we can exactly measure the solar irradiation and it's trending downhill right now, anyone using that to explain away AGW would be ridiculed. What did you expect?

Fact #1 Greenhouse gases are those that absorb and emit infrared radiation in the wavelength range emitted by Earth. Carbon Dioxide is a greenhouse gas. Fact #2 Fossil fuels emit carbon dioxide - roughly 40 billion tons of CO2 was released into the atmosphere in 2014. Fact #3 The quantity of Carbon Dioxide in the atmosphere has been steadily increasing in the atmosphere - It was roughly 320 PPM (Parts Per Million) around 1960, and currently over 400 PPM Fact #4 The temperature of Earth has been steadily climbing Which one of these facts do you take issue with?
