High school biology says green plants fix CO2 a 2 parts per million, outside an ice-age. Then there are fewer plants, and CO2 levels rise, as the temperature falls. So free CO2 FOLLOWS natural global cooling.
The 2 ppm is from the efficiency of photosynthesis to sink O.! And they are working on tweaking the genome of photoblasts here!
So Harvard says CO2 in the air has been at 2 ppm for the last 200 years! And Sheffield University can do the measurements, on air samples away from cities. I will go further; they did the measurements every 10 years for the last 200!
So no Global Warming or Climate Change: As Sheffield University is ethical, they will repay all the cash they got for climate research over the last 30 years!
