Now, there's an alarming, new warning this morning about extreme weather across the U.S. A new report saying climate change is real. And it's having a huge impact on our lives right now. Ginger, you had a chance to speak with the president about this yesterday. I did. And it was an honor to get in there and ask some questions. It's a crucial time for the president. Climate change is one of the issues he promised to attack. To get something done now, it has to happen right now for the entire administration. And the report says, it needs to happen, too, for the planet. The extremes you see today. This is as close as we are going to get to this fire. Will get even more extreme. That's the basis for the new national climate assessment Robert, released by the white house Tuesday. A report president Obama told me, we must act on. The new report, the climate situation we're in, seems pretty dire. What do you think you can get done in the next two years? The climate assessment that's been done over the course of four years, really establishes that climate change is already affecting Americans, all across the country, in every region, in different ways. That's how the report is layed out. If you live in the northeast, the report says you'll see rising sea levels and a coast prone to disaster flooding. Every street in Atlantic City is almost underwater. Southeast, facing sea level rise. It's absolutely relentless. And for those in the southwest, drought and extreme heat, which could mean more intense wildfires. But the report isn't being celebrated by all scientists. The administration prefers to address climate change by imposing regulations to try to reduce carbon monoxide emissions. You're not going to see the effects. Reporter: The president believes we should lead others around the globe. And I wanted to know if his legacy would include a decision on that controversial proposal to expand a pipeline from Montana to Louisiana. It's a project called keystone. Keystone will probably not be the determinative actor. We have to increase the solar and wind power we're using and other renewables. This is not a far away thing. We can do something about it. And the president had a question for me, which was kind of cool. As I was walking away, he wanted to know what was the worst storm I ever covered. My answer, hurricane Katrina and sandy. And I got to meet the dogs. They're ready for pictures anytime. Thank you, ginger. We're going to turn to Oscar Pistorius.
