We know the surface temperature of the Earth is warming. It has risen by .6 degrees Celsius over the past 100 years. There was a warming trend from the 1890s to the 1940s, cooling from the 1940s to the 1970s, and then sharply rising temperatures from the 1970s to today.

I'm very worried about, you know, the kid who just wonders whether America is meant for him. I really worry about that.

I have made education a top priority of this Administration because when we get it right, when every child learns, America will be a more hopeful place.
