It happens because there's too much concentration of oxygen in your body.

Instantaneous. Type you just used.

We are, right now, at 390 parts per million of CO2 in the atmosphere.

We've also talked about concentrations of carbon dioxide in the atmosphere.

So, in this room, there's 20 percent oxygen or so, and if we reduce the oxygen concentration, we will all be dead.

Condensed

I'd like to buy some concentrated, compressed gas cylinders of a lethal gas because I have these ideas, see, about wanting to suspend people.

Ultra Condensed

Extra Condensed

Semi Condensed

And we take samples of the sediment, and it tells us the CO2 level of the ocean, and therefore the CO2 level of the atmosphere.

The CO2 concentration is determined from the relative analyser output between the sample gas and the reference gas.

What it all boils down to is, of course, the sun.

How do you condense that?

If you take nitrogen out, what's left? Oxygen, pretty much.

Smells pretty strong.

The Uranium Enrichment Technology (Prohibition on Disclosure) Regulations 2004 make it an offence to make an unauthorised disclosure of uranium enrichment technology.

In most of these cases, however, low enriched uranium (LEU) can be substituted for HEU, or other techniques can be applied to achieve the required results.

I refer to enrichment and reprocessing facilities.

Well, you need about 75 pounds of it.

Are you sure this mixture of yours really works?

And currently we're working on oxygen oxygen delivery on site.

Such uranium was the material of choice for terrorists.

You better get a can of that condensed milk and some matches...

We have a program with Exxon Mobile to try and develop new strains of algae that can efficiently capture carbon dioxide from the atmosphere or from concentrated sources, make new hydrocarbons that can go into their refineries to make normal gasoline and diesel fuel out of CO2.

The primary purpose of the gas system is to provide oxygen, to replenish the oxygen that your body consumes.

In the mid 1970s, the WMO Research and Monitoring Project on Atmospheric Carbon Dioxide was initiated whose objectives were to strengthen long term monitoring for better trend determination, to predict its concentration through the next century, and to assess its possible effects on the climate.

All enrichment and reprocessing facilities must be placed under multilateral control, and a complete moratorium must be declared on the enrichment of uranium and the separation of plutonium.

HEU is not required for the generation of civilian nuclear power.

I'll make it in one sentence and then go.

Brazil has developed wide ranging production capabilities, from mining and processing of uranium to UO2 and nuclear fuel element production, all the way to isotopic uranium enrichment.

(c) Creation of the system of monitoring of greenhouse gas concentrations in the atmosphere.

Where's my oxygen mask?

We're all breathing air right now. Air is a mixture of oxygen and nitrogen, about 20 percent oxygen. About 80 percent nitrogen is in our lungs.

Oxygen White

We also know beyond doubt that emissions from human activities have substantially increased the amount of greenhouse gases (especially carbon dioxide) in our atmosphere. When the first IPCC report was published in 1990, the concentration of CO2 in the atmosphere had reached 354 parts per million (up from the preindustrial baseline of 280 ppm).

The once dominant enrichment technique, that of gaseous diffusion, is regarded as obsolescent and economically not viable for the future.

We can condense those two years to two minutes...

Several gases, including carbon dioxide, methane, and nitrous oxide, warm the planet as their concentrations in the atmosphere increase. As the world economy grows, so do emissions of these gases, accelerating the pace of human caused climate change.
