Obama pushed to keep climate action momentum going
President Obama lit the match for renewed action on climate change three weeks ago. Now advocates are clamoring for him to ignite the nation with the idea during tonight's State of the Union address. They want Obama to announce the pursuit of carbon dioxide standards for the nation's fleet of existing power plants, perhaps the biggest step the administration can take without Congress toward reduction of warming gases. But other pressures are also being applied to the White House.
