Thank you, ginger. You know about the consequences of climate change, melting ice, more frequent hurricanes and heat waves and now there's more focus on the health effects, as well. President Obama is focusing on that and Dr. Richard Besser sat down with him to talk about it. There are so many health problems that people face that concern them more than climate change. Why should they care about this issue. We know that the allergy season lasts longer. That means that asthma can be triggered a lot quicker, heatstroke could be more significant and that is a severe public health problem. Asthma is something your family has experienced. Yes. Do you worry that the environment, the climate has impacted on your own daughter? Well, you know, Malia had asthma when she was 4 and because we had good health insurance, we were able to knock it out early and, you know, you've got kids who are going to the emergency room, three, four, five times a year. What I can relate to is the fear a parent has when your 4-year-old daughter comes up to you and says, daddy, I'm having trouble breathing. The fright you feel is terrible. Quick public health lightning round. Affordable care act. On a scale of one to ten, how would you rate the success of obamacare? You know, I would put it at an 8. An 8. And the reason I don't put it at a ten is because you can always improve something. The first lady has sustain big action in terms of getting people moving. What do you think of her moves on "Uptown funk". The first lady I think we all understand is a better dancer than me. I've conceded that. I think I can sing a little bit better than her but that doesn't burn as many calorie. Who is your favorite republican? Oh, you know, I love them all. I think it's fair to say that if I endorse any one of them then they definitely don't win but, you know, our democracy works best when you got everybody making their arguments and ultimately the people will decide. Dr. Besser joins us now. I think he might have fudged a little on that last answer. The president has been working hard on climate change for a long time. This attempt to bring it home. He is trying to find way for people to connect to the issue and when he talked about it daughter having asthma and the fear he felt he's trying to connect to parents whose children will be impacted if the air quality gets worse and asthma is one of those areas where it really could happen. Okay, Dr. Besser, thanks very much.
