Obama Holds Twitter Q&A on Climate Change

President Obama held a Twitter Q&A on his newly created, and incredibly popular, @POTUS account on Thursday, fielding questions on everything from climate change skeptics to extreme weather becoming a national security issue.
The Q&A session was Obama's first from the @POTUS account, but not the first time he has answered questions on Twitter. President Obama participated in a Twitter town hall in 2011, and Twitter Q&As in August and December of 2012 on the White House's official Twitter account.
