"I agree totally we have had a global temperature increase in the 20thC – but an increase from what? ..Probably an increase from the lowest point in the last 10,000 years. We started to observe meteorology at the coldest point in the last 10,000 years."
Yeah CO2 doesn’t correlate that well to global temperature. There are dozens of other drivers of temperature. Sea levels don’t correlate well to CO2 either.
CO2 has historically been much higher for long periods and it’s not really catastrophic if it doubles or quadruples because it’s so low right now.
80 million years ago CO2 was near 2000ppm, which is breathable (though not ideal). 60 million years ago it was around 800 ppm which is when early primates started to appear. Twice what it is now. It was like 2 deg C warmer then.
The climate will change a little bit. Its always changing. Deserts will expand and tundra will contract. New areas will become habitable. Thats always true. Plants will grow faster as carbon rises.

If carbon is the problem why arent we building nuclear plants?
