Obama: 'No Greater Threat' to Planet than Climate Change

Global warming certainly has one politician's attention. 

In his weekly address President Obama cited climate change as Earth's single biggest threat. 

“Today, there’s no greater threat to our planet than climate change,” Obama said. “Climate change can no longer be denied or ignored.”

Obama pointed out that 2014 was the warmest year on record, and that 14 of the 15 hottest years measured have occurred since the start of this century. The first three months of 2015 have been the hottest start to a year of any on record. 

“The world’s top climate scientists are warning us that the changing climate already affects the air our kids breathe,” Obama said. “The Pentagon says that climate change poses immediate risks to our national security.”


Obama, who mentioned the accord he reached with China on curbing carbon emissions, said he would spend Earth Day in the Florida Everglades, a habitat the president said was "at risk" due to rising sea levels. 

One Floridian who staunchly disagrees with Obama's assessment of the threat climate change poses to the planet is Senator Marco Rubio, a man who would like to succeed him in the White House. 

"Humans are not responsible for climate change in the way some of these people are trying to make us believe, for the following reason: I believe the climate is changing because there's never been a moment where the climate is not changing," Rubio said Sunday on Face the Nation. "The question is, what percentage of that ... is due to human activity? If we do the things they want us to do, cap-and-trade, you name it, how much will that change the pace of climate change versus how much will that cost to our economy?"
