According to Dr. Patrick Moore, co-founder of Greenpeace, we are in a super low CO2 area of earths history. Historic levels of CO2 have been much higher and life could not have evolved the way we know it at today’s levels. If we go as low as 150ppm, life on earth dies. All life except maybe some primitive bacteria. Plants, animals, humans, all goes down the drain. This means that 120 additional ppm of CO2 through human industries have been a blessing in disguise for life on Earth. Release of more CO2 from the Arctic would reinforce this. We will need more CO2 – like it or not.
As temperatures rise in the Arctic, permafrost, or frozen ground, is thawing. As it does, greenhouse gases trapped within it are being released into the atmosphere in the form of carbon dioxide and methane, leading to previously underestimated problems with ocean acidification and potential mercury poisoning.
