"WASHINGTON -- Just before he and other environmentalists marched to the White House on Tuesday, climate change activist James Hansen warned he wouldn’t be able to be arrested with them this time. Hansen, a NASA scientist by day and an activist on his own time, had to be available for a press conference in the afternoon announcing that worldwide temperatures in 2012 were in the top 10 hottest ever recorded."
"'I’d be honored to be arrested with you,' Hansen said. A few hours later, he declined to discuss politics on a conference call with reporters, but he outlined how he and other government scientists arrived at their calculations as well as their concerns about future warming trends.
But as President Barack Obama approaches his second term, some of the country’s largest and most influential environmental groups and best-known advocates have drawn up blueprints for the White House to address climate change and its attendant problems: rising sea levels, droughts, more severe storms and acidic oceans. Despite doubts from others about how much could be accomplished in the coming years, they’re calling for the president to crack down on big polluters with tougher emissions rules, to reject the Keystone XL pipeline from Canada’s tar sands, and to stick to higher new fuel efficiency standards for cars. Other groups want the White House to encourage energy innovations that would curtail emissions."
