In the Permian we had 1000 year ice age! With five times the level of carbon dioxide that we have in the air today! Photosynthesis evolved, and carbon dioxide levels crashed to half the present levels! And the ice age ended. As 90% of life on earth died.
In the Jurassic there were no fossil fuels. But twice the level of carbon dioxide in the air. There was 65% more life on earth, and sea levels were 60 metres lower.
During the Jurassic there were three natural ice ages! And sea levels would have fallen more. At the end of the Jurassic 85% of life on earth died and they carbohydrates formed the hydrocarbons and carbon deposits mankind is no burning.
In last 200 years crop yields have increased by 15%, as we liberate the fossilised carbon. That used to be active biology! There is no external source of organic carbon.
In the little ice age free carbon dioxide levels in the global air were at an average of four parts per million. The ice age ended. And carbon dioxide levels fell to global average of two parts per million.
Carbon dioxide is a trace gas, which supports all life on earth! Due to global photosynthesis carbon dioxide levels have been static at two parts per million for last 200 years.
Manmade global warming was fiction from nuclear power! Propagated by paid stooges. Manmade climate change was equally as spurious fiction after a bad hurricane year 2004!
When carbon dioxide levels were at an average global level of two parts per 1,000,000. And have been since the dawn of the industrial revolution.
Man made climate change is spurious fiction by paid stooges to nuclear power! Who have no place in education at any level.
