lets say we forget about plants and human life.
lets say we only concentrate on climate and specifically global warming after all that is what the climate change believers really are on about.
lets say they are right and it's all about CO2.
what happens when we get rid of all the CO2? we freeze and or we fry...
where do you think the CO2 in the thermosphere comes from?



to deplete the CO2 in the atmosphere means you cut the level of protection the CO2 in the thermosphere provides for us.
the CO2 in the lower atmosphere along with other so called Greenhouse gasses provides us with a comfortable atmospheric envelope in which to live... some of the time remember water vapour is the gas which has the most profound effect of all the greenhouse gasses, it is also by far the most prolific.
Why some of the time? because we have a natural cycle where we have very long periods of cold... which we call ICE AGES..
Personally I doubt we will be ready to cope with the next one when it arrives and it is due.
