President Obama will address the nation from Georgetown University on Tuesday to share details on how he plans to address the threat of climate change, a promise he made in his inaugural address back in January. According to The Washington Post, the president will specifically announce new regulations on the country's power plants in an effort to reduce greenhouse gas emissions. It's an effort not only to meet the promise he made in January but also to achieve an international pledge his administration made to lower greenhouse gas levels to 17 percent below their 2005 levels. While a video released by The White House doesn't specifically address lowering greenhouse gas levels, the president's narration does say that he'll lay out "a national plan to reduce carbon pollution, prepare our country for the impacts of climate change, and lead global efforts to fight it."

President Obama also used his video message as a way to tout the economic opportunities that could come along with his battle against climate change. "We'll need scientists to design new fuels, and farmers to grow them," the president said. "We'll need engineers to devise new sources of energy, and businesses to make and sell them." This speech will come a few months after Tom Donilon, the national security advisor to President Obama, called climate change a "national security threat" and said the administration needs to take steps "to reduce the greenhouse gas emissions that drive climate change."
