The task of cutting greenhouse gas emissions enough to avert a dangerous rise in global temperatures may be far more difficult than previous research suggested, say scientists who have just published studies indicating that it would require the world to cease carbon emissions altogether within a matter of decades.Think about what that would mean: not "keep them in line with Kyoto Protocols," but zero.
No fires. No cooking. No milk farms. No cars. No trucks. No planes. No cigarettes. No cigars. No farting. No belching. No breathing.
Schmittner, lead author of a Feb. 14 article in the journal Global Biogeochemical Cycles, said his modeling indicates that if global emissions continue on a "business as usual" path for the rest of the century, the Earth will warm by 7.2 degrees Fahrenheit by 2100. If emissions do not drop to zero until 2300, he calculated, the temperature rise at that point would be more than 15 degrees Fahrenheit.This matters, because even a three degrees rise in global temperatures would have serious, possibly irreversible, consequences for the planet and for even human survival.
So I'm watching this show last night on my TV...
