Our energy sources are not sustainable.

For me, what's important.

So what needs to be done?

There's two great forces that are both volitional but inevitable.

Climate change is real.

And, of course, Arctic communities are toast.

We have now, and are the first generation with, the power to do this.

75 minutes.

In the U.K., the Thames Barrier protects London from storm surge.

Okay? We cannot reduce animal numbers to rest it more without causing desertification and climate change.

Don't we already know how they affect temperatures?

less stuff.

You know, this is really an infinite thing.

We're not even slowing down.

And the same thing is true for people who are in absolute crisis. Right?

It may surprise you that it's not only climate.

We, the people, still believe that our obligations as Americans are not just to ourselves, but to all posterity.

They've got no points of land more than about six feet above sea level.

And he used to be the USA Today Monday morning guy.

And I'll mention them the emission of CO2, climate change, the fact that we have the responsibility of the acceleration of the climate change.

As we see the spread of it, we see national hubs emerging.

And we know the solar output's not constant through time.

And more CO2 causes more warming.

These are motorized devices that are controlled by little electrical signals from your muscle.

If we apply the best architectural design, climate engineering design, we won't get much better.

They are both two branches of the same field of atmospheric science.

So, we're not sure where this story is going to end, whether it's got a happy or sad ending.

And I think it really summarizes where we are here.

So those are all natural causes of climate change.

You know the climate.

We see and feel the climate changes, the droughts and the flooding, the storms and the heat.

The climate of England is milder than of Scotland.

The climate of England is similar to that of Hokkaido.

The climate of Japan is not like that of England.

And even at that time, with the introduction of agriculture, 8,000, 10,000 years ago we started to see climate change.

What's new is just the degree of it.

I'm just going to talk about two things.

The climate here is milder than that of England.

The climate here is milder than that of England.

The climate of England is milder than that of Scotland.

The climate of Japan is milder than that of England.

The climate here is like that of Hokkaido.

The climate of Florida in the wintertime is milder than that of Iowa.

The climate of Kochi is warmer than that of Kyoto.

I can't think of anything else that's happened in my lifetime that way.
