U.N. Panel: We Have 15 Years to Stop Climate Change

After that, it'll be too expensive to stabilize the climate.

A new report from the U.N.'s Intergovernmental Panel on Climate Change (IPCC) announced Sunday that the world has taken so long to act on global warming that we have just 15 years to make a massive effort before slowing climate chanage becomes impossibly costly. The report said it remains technically possible to slow warming, but that even European countries that have made efforts haven't done nearly enough. The findings will likely put even more pressure on a major global treaty expected to be completed in 2015 and to take effect in 2020. On the bright said, researches said the cost of alternative energies is falling so rapidly that implementing them on a mass scale is now practical.
