Led by Oregon climate scientist Andreas Schmittner the paper suggests the rate of warming from a doubling of atmospheric carbon dioxide may be less than the most dire estimates. Specifically, if atmospheric carbon dioxide levels are to double from pre-industrial levels of 280 ppm to 560 ppm, the researchers say Earth’s average temperature is likely to rise from 1.7 to 2.6 Celsius degrees, a decrease from the previous, accepted range of 2 to 4.5 degrees.“If these paleoclimatic constraints apply to the future, as predicted by our model, the results imply less probability of extreme climatic change than previously thought,” Schmittner said.
This may not seem like a huge deal but I agree with the author of the original Chronicle article, if these results hold up this deals a substantial blow to apocalyptic climate change movement. I'm very certain that the earth, and human kind, could withstand such mild climate shifts if they did occur.
