Ochre, iron oxide, charcoal. Oxy, stay with us.

And they changed the atmosphere.

I'm really keen to try and minimize the addition of any chemicals.

Aluminum buffer action, aluminum hydroxide is what we think it is, uh, plus the barium carbonate, strontium titanate, strontium oxides, barium oxides, probably some aluminum oxides in there.

Iron and oxygen are elements.

This isn't Volvos this is volcanoes.

Platinum dioxide, right? No.

Everyone take their vitamins this morning?

This is the breakdown product of the bedrock, that organisms are busy munching their way through.

When it comes to supplements, should you be taking them?

Some, like aluminum oxide, tends to sequester the moisture.

We need to breathe.

Unlike nitrates and peroxides, it gives off no signature.

And that wasn't easy because poisons were everywhere.

We'll look at ocean warming.

A strand of hair that has titanium dioxide.

The dioxide's too hard to keep wet.

Thorium oxide for a catalyst bed.

And then above that, you're just adding more and more hydroxide.

So, fungi and mycelium sequester carbon dioxide in the form of calcium oxalates.

We stopped tilling, so that we could prevent greenhouse gasses from going into the air.

Where have essentially, you have an equal amount and very

A very simple example is this When the world was primarily plants, the environment, which had carbon dioxide and some oxygen in it when they first started,

Trees give off oxygen and absorb carbon dioxide.

If you oxidise an alcohol you get an aldehyde but what do you get if you oxidise an aldehyde?

Do this in just a jet in a very simple way.

Tropical rainforests produce oxygen and consume carbon dioxide.

The acid oxidises after the creature's death, completely neutralizing.

Each cylinder is about 10 percent ancient air, a pristine time capsule of greenhouse gases carbon dioxide, methane, nitrous oxide all unchanged from the day that snow formed and first fell.

Inert nitrogen, high concentration of carbon dioxide crystals, methane...

Makes the rocks crumble, and the first step in the generation of soil.

Now, as we breathe, we produce carbon dioxide, and that carbon dioxide needs to be scrubbed out of the system.

The botanical names are in front of you.

They take iron and manganese minerals within the bedrock and they oxidize them.

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.

In fact, what's being absorbed is something like 25 percent of our emissions, which then leads to acidification or lower alkalinity in oceans.

Everything that we need to make an atmosphere on Mars, and to make a livable planet on Mars, is probably there.

If you fracture it, you can look at the fact that it's nanostructured.

This is regularly several hundred parts per million.

10 times better than our fog catching nets.

You see, hydrofluoric acid won't eat through plastic.

You know, a little sodium hydroxide, shut the lid. No harm done. Then we're golden.

When the ocean absorbs a lot of CO₂, the water becomes more acidic.

The primary ingredients in geoengineering are specifically the oxides of metals, including aluminum oxide.

Different amounts of UV hit different parts of the Earth at different times of year, so you can actually work out those stores of nitric oxide the nitrates, nitrites, nitrosothiols in the skin cleave to release NO.
