North Report's link to the Gaurdian article showed this interesting fact about the COP 15 pledges on Day 8:
Calculation by Climate Interactive groups special software:
"If the promises that are on the table now on Day 8 were kept, such as the American offer of 4% below 1990, the Chinese promise to reduce "energy intensity", the EU pledges, and so on, that by 2100 the world's CO2 concentrations (currently 390 ppm) would be 770 ppm."
770 ppm will translate into global average temperature increases of hitting 6oC within 100 years of being over 400 ppm. 770 ppm would spell utter disaster - the world has NEVER warmed up that fast before. Naturally caused temperature increases have taken 1000s of years, not 100 years.
