As Barack Obama nears the end of his time as president, he is able to devote more of his attention to the causes that mean the most to him, including climate change. Not only has he engaged in a series of high-profile negotiations with international leaders about the issue, but he's also guest-hosting DNews this week to connect with the average citizen on a more personal level.
