Carbon dioxide is PART of air and besides contributing to warming is changing the pH of ocean water. Any major disruption to the food chain, especially the lower end, will be catastrophic. Higher heat in the lower 48 will cause a drop in production of wheat, this last fall was very dry and winter wheat did not do well, you can check out harvest forcasts for the Dakota's. Don't count on Delta becoming the next wheat bowl, higher temps will mean greater evapotranspiration, so less moisture in the soil to sprout grain in the spring. Winter ticks will show up and what will be the effect on caribou, moose and sheep? How about fur animals, what insect borne virus will birds bring from South America? Global warming has negative as well as positive consequences.
Oh and China has 7 of the 10 largest solar firms, and due to popular demand has backed off on building coal plants. We don't need to do that because we have renamed all of ours "clean coal", that's helped a lot already.
