>>11227074>But the effect is small
What does "small" mean? It matches the observed radiative forcing. What other forcing is larger?>and to increase the temperature buy a certain increment you need to double the CO2 level.
CO2 emissions have been increasing exponentially.>And then the grand solar minimum will cause cooling till about 2050 no matter what.
Wrong, it has a minuscule effect compared to CO2 emissions. Pic related.
Solar forcing has been dropping for decades while ther temperature continues to increase. Where are you getting this nonsense?>If CO2 was the only cause, how did the temperature drop in the past?
I know it's very hard for you to keep track of two things in your head, but multiple things can effect the temperature at different times. Greenhouse gases have always had an effect on Earth's temperature and always will. This does not mean they are the only thing that effects the temperature or must always be the dominant cause of changes. But they are right now. Seriously think about that.
