Climate Warnings, Growing Louder

Given new evidence on carbon pollution, President Obama should get moving on global warming.

The news that atmospheric concentrations of carbon dioxide, the most important global warming gas, have hit 400 parts per million for the first time in millions of years increases the pressure on President Obama to deliver on his pledges to limit this country’s greenhouse gas emissions.

America cannot solve a global problem by itself. But as Mr. Obama rightly observed in his inaugural address, the United States, as both major polluter and world leader, has a deep obligation to help shield the international community from rising sea levels, floods, droughts and other devastating consequences of a warming planet. In his State of the Union speech, he promised to take executive action if Congress failed to pass climate legislation.

Which is just what he will have to do. The prospects for broad-based Congressional action putting a price on carbon emissions are nil. The House is run by people who care little for environmental issues generally, and Senate Republicans who once favored a pricing strategy, like John McCain and Lindsey Graham, have long since slunk away. Meanwhile, Republicans on the Senate Environment and Public Works Committee have spent the last two weeks trying to derail Mr. Obama’s nominee to run the Environmental Protection Agency — a moderate named Gina McCarthy. Ms. McCarthy has served two Republican governors (Mitt Romney was one) but is considered suspect by the right wing because she wants to control carbon pollution, which is driving global temperatures upward.
