>> I did the documentary
because these guys thought
there was a story to tell.
And the story is I want to have
as many scientific
literate people
as possible of all ages
around the United States
and around the world.
So if you get
that science matters.
It doesn't mean that everybody
has to be a scientist
or an engineer.
I'm an engineer, believe me,
you don't want a world
full of engineers.
But we want people
to respect it.
So I signed a deal,
almost 3 years ago,
to have no creative
control of the film.
And then the last few months
it's been clear wouldn't
it be better Bill
if you don't even see it
at all-until that premiere.
So that's where
we are right now.
>> Wow.
This is where the magic happens.
This is where the ice
core's drilled.
Ice cores are the best
archive of the past.
>> The discoveries
that are made in science,
notably climate change,
we want people
to get to work on.
Instead of ignoring.
I mean understand James Hansen,
who is the head of Goddard
Institute of Space Studies
- GISS which is part of NASA,
testified in front of
the U.S. Congress in 1988
about this problem.
Which was discovered nominally
by comparing the Earth
to Venus to Mars
and you realize
that the reason Venus
is so extraordinarily hot
is because of
the Greenhouse Effect.
And the Greenhouse Effect
is a huge effect here on Earth.
In the last year
we got above 400 parts
per million of carbon
dioxide worldwide
- and we did it in just
a couple decades-and
it's changing the world.
And it's the speed everybody.
I say it over and over.
It's the speed that is changing
that's the problem.
I think we've elected
an administration
that's supporting people
who are anti-science.
I don't know
how long that'll last.
I think it's this thing
that people in psychology
call cognitive dissonance,
we have this worldview
that disagrees with the evidence
so you just dismiss
the evidence.
And you dismiss the authorities
that are providing the evidence.
A classic example of this
goes back to I think Aesop
- had the fox and the grapes.
Can't reach the grapes.
He or she, the fox,
has conflict.
So he or she says well
the grapes must be sour.
Then the conflict is resolved.
The grapes are no good
anyways so I'm alright.
The world is not changing,
the people providing that
evidence are in a conspiracy
and they're evil and bad.
And then you're ok.
Then your worldview
is consistent.
You have no more dissonance.
But the world is changing
and the evidence is compelling
and the authorities
are authorities-and
so we wanna get people
to change their minds.
