The researchers had to suit up just to enter it.

We inject our own aerosols into the atmosphere, and we have trace gases, and not just carbon dioxide it's methane, ozone, oxides of sulfur and nitrogen.

Well this was really cool.

I'm taken back to the boat, I'm given a gas mask

He bleeds out pigs.

And then we have two parameters which we were not able to quantify air pollution, including warming gases and air polluting sulfates and nitrates, but also chemical pollution.

And here's the weapon, it seems, that it did so over the last 500 million years.

sulfuric acid.

Six hours later, up goes the temperature.

One thing those people did out there was take this technology of hydrogen sulfide, which is this start up company that's burning venture capital very quickly, and they fused it with another company that sells another toxic gas that's more toxic than hydrogen sulfide, and they give it to newborn babies who would otherwise die from a failure to be able to oxygenate their tissues properly.

And here's the really important point.

This is regularly several hundred parts per million.

More recently, into the Black Sea, where we're exploring.

You're in an accident.

But there's a far worse danger confronting us.

It's a liquid sulfur.

But I also am in the fueling business.

The next big issue, deforestation.

This past May was the warmest worldwide on record.

This geo engineering idea, in it's simplest form, is basically the following.

This is what accumulates in the tar sands of

Embedding nanoparticles in a material for instance, always.

That's a key trend, which is decentralization, moving from centralized nuclear power plants and

If I'm the only chemist that he's got.

And with money we got from DARPA, we could show just that.

Gas lines?

Americans spent, in 2001 11 percent of all pesticide use was done on lawns.

This was a temperature of colossal magnitude.

They stop complex life from existing.

like gasoline or sulfuric acid, methane, and nylon.

You might be wondering, what does SDS PAGE even stand for.

As the pressure grew, so did the heat, until a chemical reaction transformed the organics into hydrocarbon fossil fuels

( coughing ) Gus?

Gus.

On the roof. Gus?!

( clattering ) Gus!

Rotten! ( grunts ) Gus.

Gas?

We have to go in with protective suits and breathing gear, and 30 parts per million of H2S will kill you.

And so, I added B vitamins, sulfur and antixidants to my daily regimen.

I don't know if anybody might hail from northeastern Pennsylvania, but this is where I spent my first 19 years with my little young lungs.

And so we thought, like in a game of musical chairs, might we be able to give a person some hydrogen sulfide, and might it be able to occupy that place

And so, we wanted to find out might we be able to use hydrogen sulfide in the presence of cold, and we wanted to see whether we could reproduce this skier in a mammal.

A lot of hydrogen's produced today in the world.
