OXFORD - U.S. wavering on climate commitment could undermine action to save the planet, the director of Germany's Potsdam Institute for Climate Impact Research said on the sidelines of a conference on Monday. Preserving the Greenland ice cap was the defining action needed to prevent several meters of sea level rise and warming which would threaten the world's food and water supplies, Hans Schellnhuber told reporters.
The doubts of many Republican U.S. senators over the practicality of a draft, domestic carbon-cutting law undermined the chances of strong global action soon, he said. "It's a deeper problem in the United States, if you look at global polls about what the public knows about climate change, even in Brazil, China you have more people who know the problem, who think that deep cuts in emissions are needed," he said. "The United States is in a sense climate illiterate still. If you look at what people in the Republican party think about this problem it's very unlikely you come up with something."
EDIT
Pledges so far would take overall reductions by all industrialized nations to a maximum of 15 percent, Reuters calculations show. President Barack Obama aims to return U.S. emissions to 1990 levels by 2020.
"We are not even near the reductions that are necessary," said Schellnhuber.
