				 Obama has said he sees addressing climate change 
				as an urgent national security issue. With less than two years 
				left in his presidency, he wants to finalize U.S. rules to curb 
				greenhouse gas emissions from power plants, and marshal support 
				for a global deal to limit climate-changing carbon pollution. 
				 
				The Everglades will give Obama a vivid backdrop for talking 
				about his goals, the White House said, noting rising sea levels 
				and shrinking freshwater in the unique ecosystem are killing 
				grasses and threatening groundwater supplies for a third of the 
				people who live in the state. 
				 
				"This is really ground zero," said Christy Goldfuss, a top 
				environmental adviser to Obama, in a briefing with reporters. 
				 
				The day trip also gives Obama a chance to draw a contrast with 
				Republicans fighting his plans. 
				 
				Republican Senate Majority Leader Mitch McConnell has warned 
				other countries that a future Republican president could reverse 
				Obama's regulations. 
				 
				Florida Senator Marco Rubio, who has entered the race to be the 
				Republican presidential nominee in 2016, has said humans are not 
				responsible for climate change. 
				 
				Former Florida Governor Jeb Bush, who also is considering a 2016 
				run, has said his concerns about the economy outweigh his 
				concerns about climate. 
				 
				Many Americans are "psychologically distant" from climate 
				change, seeing it as a far-off problem affecting distant lands, 
				and do not share Obama's sense of urgency, said Anthony 
				Leiserowitz, director of the Yale Project on Climate Change 
				Communication, which surveys Americans on their climate views. 
				 
				"It's like a famine in Africa: people basically say, 'I don't 
				like it, I wish somebody would do something about it, but I 
				don't see what I can do and how it directly relates to my 
				life,'" he said. 
				 
				To try to bring the issue closer, the White House has started a 
				social media campaign, encouraging people to post photos of 
				parks and nature they care about. 
				 
				The idea could be effective, Leiserowitz said, noting only four 
				percent of Americans say they hear people they know talking 
				about climate change. 
				 
				"We don't talk about it. No wonder it's a low priority," he 
				said, explaining people place more trust in what they hear from 
				family and friends than what politicians say.
