Given that Earth's atmosphere composes:
Nitrogen – 78 percent
Oxygen – 21 percent
Argon – 0.93 percent
Carbon dioxide – 0.038 percent
Water vapour and other gases exist in small amounts as well.
And that plants require CO2 to live - How is reducing CO2 a good thing? I mean if CO2 levels were 3,000 - 7,000 parts per million during the time of the dinosaurs and all plant life will die out at 150 ppm why is our current level of 400 ppm SO BAD?
Did anyone wonder how the civilisations of the Mediterranean were able to exist in what is now desert? How did they used to grow grapes in England? Remember when the Thames River froze solid in the 'Little Ice Age 1645–1715'?
When there are massive forest fires, volcanoes and animals breathing for billions of years how did the Earth not succumb to global warming and turn into Venus already? There are self regulating forces at play with big tolerances that keep the Earth and it's ecosystems on an even keel.
There are 2 massive heat sinks that draw heat from the atmosphere. The oceans and space. The ocean temperatures lag the atmospheric temperature by 1,000 years denoting a slow but steady absorption and re radiation of heat as the atmosphere heats and cools in response to solar activity. Space is a constant drain on heat away from the atmosphere and is insatiable, slowed in main by the amount of cloud or dust in the air, which ironically also reduces heat entering the atmosphere in the first place.
