well, until continental ice sheets in Greenland and Antarctica melt and raise sea level, requiring tens of millions to evacuate, there's still hope. *but*, as Gore stresses, weather is non-linear, meaning, there can be a tipping point when just a little change in the atmosphere can cause a vast change in climate. on the positive side, the government of Japan is considering liquifying CO2 and storing it underground, but that's just 1/6 of Japan's emissions by 2020.

Japan hopes to slash greenhouse gas emissions and fight global warming with a plan to pump carbon dioxide into underground storage reservoirs instead of releasing it into the atmosphere, an official said Monday.
The proposal aims to bury 200 million tons of carbon dioxide a year by 2020, cutting the country's emissions by one-sixth, said Masahiro Nishio, an official at the Ministry of Economy, Trade and Industry. Introduced last month, the plan is still under study.
