Climate change deniers are almost all
old. They're almost my age and older.
Very - once in a while you meet a young person who's a climate change denier, but it's
very, very seldom.
How do you know the world
is round? What do you mean how do we know
the world is round? The ancient
Greeks knew the world was round. How do you
know the climate is changing? Because
we've studied it. We've looked at the
bubbles in the ice, the pollen in the
pond silt, the tree rings we have studied,
we scientists have studied it. Why do you
think everybody's so concerned? Just this
whole thing that there's a conspiracy of
scientists to get rich from government
grant. Yeah, some as I joke, some of
those guys drive Honda Accords.
That's the kind of cash they're rolling in. No, you don't get rich studying climate change.
So, the reason scientists are so
concerned is because this situation is
very serious. It's the whole thing is the
speed. It's the speed that the world's
climate is changing. It used to be
warmer in ancient dinosaur times.
There used to be an inland sea in what is now Wyoming, but that's not the way it is now.
It's how fast things are changing we're
not gonna be able to raise enough food
to feed everybody, we're not gonna be
able to ship it to people around the
world if we don't get the work.
