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.

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.

Don't we already know how they affect temperatures?

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

There are very, very few people who don't know now about what is happening in the Arctic.

Our energy sources are not sustainable.

You know, this is really an infinite thing.

75 minutes.

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

So what you'd be wondering, watching the Human Show, is are we going to confront and address the catastrophic climate shift that may be heading our way by growing our consciousness, or are we going to continue to retreat?

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

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

less stuff.

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

And, of course, Arctic communities are toast.

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

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

We're not even slowing down.

So I decided to do this symbolic swim at the top of the world, in a place which should be frozen over, but which now is rapidly unfreezing.

We're running out of land.

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

You know the climate.

We've never had this before because Kyoto didn't work.

Now plants are under threat.

That is the change needed to restore energy balance and prevent further warming.

And more CO2 causes more warming.

So this is a call, a plea, to the incredibly talented TED community.

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

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

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

Number two, very quickly

Wouldn't it be awesome if we all had BLlS on our phones?

And I know, in the light of human suffering and poverty and even climate change, one would wonder, why worry about a few cats?

So those are all natural causes of climate change.

And I think it really summarizes where we are here.

And I do believe that there is a strong possibility that if we work together, we can get that agreement to Copenhagen.

And you need to deal somehow break the link between human actions that change climate, and the climate change itself.

We're saying that you cannot solve the problem of climate change in one country you've got to involve all countries.

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

Yet, there was more energy coming in than going out.

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

The climate is changing.
