And I also like to think of offices as being a temperate grassland.

But, in fact, they're grassland habitats for grassland birds and plants.

Compared to grassland management

Our country's climate is temperate.

This picture is a typical seasonal grassland.

You're more temperate than I'd be in your situation.

So on this bit of grassland, we'll do it, but just in the foreground.

It could destroy the Great Bear Rainforest, the largest temperate rainforest in the world.

They help moderate the temperature in our temperate zones and give us stable weather.

One who was temperate among them, said Did I not say 'Why don't you priase God?'

And when they reached Central Asia, they reached what was effectively a steppe super highway, a grassland super highway.

Now, looking at this grassland of ours that has gone dry, what could we do to keep that healthy?

And the Great Bear Rainforest is generally considered to be the largest coastal temperate rainforest ecosystem in the world.

The north coast of California has rainforests temperate rainforests where it can rain more than 100 inches a year.

Now, ironically, what happened was it was eliminated from all the temperate zones, which is where the rich countries are.

They grow in tropical forests like this one and they also grow in temperate rainforests, that we find in Washington state.

We thought basking sharks were temperate animals and lived in our latitudes, but in actual fact, they're obviously crossing the equator as well.

In fact, temperate and tropical rainforests each produce a vibrant animal orchestra, that instantaneous and organized expression of insects, reptiles, amphibians, birds and mammals.

But fire also leaves the soil bare, releasing carbon, and worse than that, burning one hectare of grassland gives off more, and more damaging, pollutants than 6,000 cars.

Now, all of that grass you see aboveground has to decay biologically before the next growing season, and if it doesn't, the grassland and the soil begin to die.

Still, in this place, in this grassland where you can see our very first office there on that hill, four years later, there is this one green blop on the Earth's surface ... (Applause)

One thing I want to point out is that underneath these live epiphytes, as they die and decompose, they actually construct an arboreal soil, both in the temperate zone and in the tropics.

But if you do not look at grasslands but look down into them, you find that most of the soil in that grassland that you've just seen is bare and covered with a crust of algae,

I began helping a family in the Karoo Desert in the 1970s turn the desert that you see on the right there back to grassland, and thankfully, now their grandchildren are on the land with hope for the future.

Unlike fins and blues, which disperse into the temperate and tropical oceans, the humpbacked whales congregate in local traditional breeding grounds, so they can make a sound that's a little higher in frequency, broader band and more complicated.

In the tropics, raindrops are not formed from ice crystals, which is the case in the temperate zones, you need the trees with unclear , chemicals that come out of the leaves of the trees that initiate the raindrops.

The western border of the boreal in British Columbia is marked by the Coast Mountains, and on the other side of those mountains is the greatest remaining temperate rainforest in the world, the Great Bear Rainforest, and we'll discuss that in a few minutes in a bit more detail.

So the Great Bear Rainforest is just over the hill there, within a few miles we go from these dry boreal forests of 100 year old trees, maybe 10 inches across, and soon we're in the coastal temperate rainforest, rain drenched, 1,000 year old trees, 20 feet across, a completely different ecosystem.

So I then began looking at all the research plots I could over the whole of the Western United States where cattle had been removed to prove that it would stop desertification, but I found the opposite, as we see on this research station, where this grassland that was green in 1961, by 2002 had changed to that situation.

First, four small caps are placed at the four ends of the separation beaker. Then, whilst distilling, the beaker is turned by 60 degrees after a certain temperate has been reached. In doing so, at the end of the distillation, all four caps contain a specific liquid, depending on the boiling point of the liquid distilled.

We are already doing so on about 15 million hectares on five continents, and people who understand far more about carbon than I do calculate that, for illustrative purposes, if we do what I am showing you here, we can take enough carbon out of the atmosphere and safely store it in the grassland soils for thousands of years, and if we just do that on about half the world's grasslands that I've shown you, we can take us back to pre industrial levels, while feeding people.
