" Fewer people die of heat than die of cold. "
More people will die from the heat. See: dew Point.
"Longer growing season."
lol, excessive heat is bad for crops. And some areas of the earth are already losing farming capacity, not higher yields. major commodity crops like corn, rice, and oats are starting to experience reduced yields due to heat stress and changes in water availability.
" Bring on the CO2."
We produce more CO2 then the plants can handle. BTW, too much CO2 is bad for plants. Just like to much O2 is bad for people.
"We can handle the heat. We will be fine."
Why can't you people grasp the simple fact that as we keep producing more greenhouse gasses, the heat will keep going up? WHy are you so ignorant you think civilization can stand that level of heat growth?
