Not again. Read the book. You are so out of it. Scientists Find New Global Warming 'Time Bomb’ by Seth Borenstein WASHINGTON - Global warming gases trapped in the soil are bubbling out of the thawing permafrost in amounts far higher than previously thought and may trigger what researchers warn is a climate time bomb.... ‘‘The higher the temperature gets, the more permafrost we melt, the more tendency it is to become a more vicious cycle,’’ said Chris Field, director of global ecology at the Carnegie Institution of Washington, who was not part of the study. ‘‘That’s the thing that is scary about this whole thing. There are lots of mechanisms that tend to be self-perpetuating and relatively few that tend to shut it off.’’ Message 22790954 Positive feedback loop...the hotter it gets, the hotter it gets. When snow and ice melts, albedo decreases, more heat gets absorbed by the earth. Hotter and hotter. As tundra gets replaced by trees, CO2 consumption from the trees will be more than tundra, but the albedo, again,is less, and the end result is even a faster temperature change. Nature-408 (2000), pg 187 And, how do plants grow with more CO2? Double CO2, rice is 6% more, wheat 8%; opposed to that are the detrimental effects of increased temperature, decreased soil moisture, increased O3, and crop production will be down. You really don't understand any of this, as much as you pretend to. You aren't a follower of Fred Palmer, are you?
