But I just think it's really important for people to come out.

I agree.

Yeah, he and his wife are both brilliant.

I enjoy working with them.

But anyway, back to your important question.

In the last 20 years,

We've seen increased global warming pollution emitted into the sky and the heat trapped by the accumulated amount.

You know, it goes up there and stays there for quite a long time, unfortunately.

And the accumulated amount now traps as much extra heat each day.

as would be released by 750,000 Hiroshima-class atomic bombs exploding every day on the Earth.

It's hard to express this in numbers that are accessible and comprehensible, but the amount of harm being done is amazing.

By the way, behind me, what you see there is the thin blue line.

That's a picture taken from the space station.

And that thin blue line is where...

all the oxygen is, and that's where all of the global warming pollution hangs out.

It just is stuffed into that thin blue line.

And here's the thing, that line is so thin

that if you could drive a car straight up in the air at interstate highway speeds, you'd get to the top of that blue line in about five minutes.

It's really shockingly thin.

You could walk it in an hour.
