My research indicates that the Siberian peat moss, Arctic tundra, and methal hydrates (frozen methane at the bottom of the ocean) all have an excellent chance of melting and releasing their stored co2.Recent methane concentration figures also hit the news last week, and methane has increased after a long time being steady.The forests of north america are drying out and are very susceptible to massive insect infestations and wildfires, and the massive die offs - 25 % of total forests, have begun.And, the most recent stories on the Amazon
forecast that with the change
in rainfall patterns one third of the Amazon will dry and turn to grassland, thereby creating a domino cascade effect for the rest of the Amazon.With co2 levels risng faster now that the oceans have reached carrying capacity, the oceans having become also more acidic, and the looming threat of a North Atlanic current shutdown (note the recent terrible news on salinity upwelling levels off Greenland,) and the change
in cold water upwellings, leading to far less biomass for the fish to feed upon, all lead to the conclusion we may not have to worry about NASA completing its inventory of near earth objects greater than 140 meters across by 2026 (Recent Benjamin Dean astronomy lecture here
