And, of course, Arctic communities are toast.

less stuff.

We're running out of land.

And on up to Greenland.

The lists go on and on.

And this is a huge, huge energy savings, because what comes out of our tailpipe is really just the beginning of the story with climate emissions from cars.

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

So what needs to be done?

At any rate, it was a fascinating place, but unfortunately, Australia didn't stay this way.

Our energy sources are not sustainable.

For me, what's important.

This is a system that could put the next generation at the front lines of gathering environmental data.

The climate affected the growth of trees and plants.

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

Climate change is real.

Do you think our climate has an influence on our character?

This talk is about being prepared for, and resilient to the changes that are coming and that will affect our homes and our collective home, the Earth.

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.

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.

And this long term change in the tilt, this might have played to some of the long term climate change, maybe it might have contributed on some level to some of the Ice Ages that have formed over Earth's past, but for the sake of thinking about our annual seasons, you don't have to worry too much, or you don't have to worry at all really about this variation.

You know, this is really an infinite thing.

But it's being balanced like that in equilibrium.

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?

The climate affects people in every land.

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

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

What we don't know is the exact, precise, immediate impact of these changes on natural climate patterns winds, ocean currents, precipitation rates, cloud formation, things that bear on the health and well being of billions of people.

No sir, it's the flux.

We're not even slowing down.

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.

We have great international experts within India telling us that the climate is changing, and actions has to be taken, otherwise China and India would be the countries most to suffer from 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.

This is an analysis we've done, where on the left is where the crops are today, on the right is where they could be based on soils and climate, assuming climate change doesn't disrupt too much of this, which is not a good assumption.

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.

This bad weather will affect the crops.

And more CO2 causes more warming.
