High School biology teches that plants take in CO2 to grow. So in the afternoon around the world, CO2 fixed at 2ppm today. Levels are higher above the Arctics. They also rise in a ntural ice-age.
In the Jurassic the number was 4ppm. There was 65% more life on Earth, sea levels were 60 meters lower – so you could walk from th UK to Europe. Incidentally, 1 of the 3 natural ice ages in the Jurassic lkast 650 million years. With CO2 at 8ppm – 4 times than possible today.
Ever university student is familiar with the carbon cycle. Man's extra CO2 has increased active life by 15%, but can't affect the trace of CO2 in the air.
So all the Global Warming pundits were talking biological rubbish – funded by nuclear power. These are nto the people we want in education.
Or even alive. All those Global Warming PhDs must instantly be recinded.
