Obama’s Power Plan May Be Historic But It Won’t Save the World

President Barack Obama’s plan to reduce carbon pollution -- acclaimed by supporters, reviled by opponents -- won’t be enough to save the planet.

That’s the view of scientists, including European researchers who study climate policies. It’s a numbers game: Even if the U.S., China, Europe and other nations meet their commitments on cutting carbon, world temperatures will rise by 3.1 degrees Celsius (5.6 degrees Fahrenheit) on average by 2100, too much to avoid calamity, they say.
