Our energy sources are not sustainable.

For me, what's important.

So what needs to be done?

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

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?

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

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

We're advising various island states in the climate change negotiations, which is suppose to culminate in Copenhagen.

And I consider India and China the best partners in the world in a good global climate policy.

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.

A global plan of action with a world conservation union, the IUCN, is underway to protect biodiversity, to mitigate and recover from the impacts of climate change, on the high seas and in coastal areas, wherever we can identify critical places.

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.

I hope that you will all, if you've been moved by this presentation, join with the growing international community to get Canada to step up to its responsibilities, to convince Canada to go back to being a climate change champion instead of a climate change villain, and to say no to the tar sands, and yes to a clean energy future for all.

And of course, all crop losses are related to weather modification problems.

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.

The game retreated northward

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

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.

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

The climate is changing.

Now as you know, a great deal of time is spent, in this country and around the world, inside the climate debate, on the question of, What if the IPC scientists are all wrong?

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