Besides water, the plume also contained carbon monoxide, carbon dioxide, ammonia, sodium, mercury and silver.

But these will not stabilise levels of atmospheric carbon dioxide - only slow the rate of increase.

Sperm whale poop helps fertilize algae, which in turn suck up carbon dioxide via photosynthesis.

The resulting carbon dioxide cloud rushed downhill, asphyxiating 1, 700 people and thousands more animals.

Carbon dioxide is like nitrogen in many ways, but if it is mixed with limewater, it causes the clear liquid to because milky, while nitrogen dose not. This is the test for carbon dioxide.

When carbon unites with oxygen, it forms a colorless, odorless, and tasteless gas called carbon dioxide, which is heavier than air and will extinguish a flame.

The concentration of carbon dioxide in the atmosphere is rising and climate change is occurring, both due to human actions...

The “carbon dioxide intensity of gross domestic product” in China will halve in the next decade, the report says.

We will invent much improved methods to harness the sun, the wind, nuclear power, and capture and sequester the carbon dioxide emitted from our power plants.

Currently half the carbon we release into the atmosphere gets absorbed by land and sea-much of it by plants, which take in carbon dioxide in the process of photosynthesis.

Synthesizing the work, Broecker accurately predicted "that the present cooling trend will, within a decade or so, give way to a pronounced warming induced by carbon dioxide."

Dr Jiao estimates that the amount of carbon stored by the oceans in this way is equal to the amount in the atmosphere, in the form of carbon dioxide.

In the meantime, other scientists had identified a receptor in a group of neurons that enable fruit flies to smell carbon dioxide, which signals the presence of a good meal of tasty yeast.

Also likely to be axed: a new 'ecological plastic' that emits less carbon dioxide over the course of its life than more traditional alternatives, but which is costlier to produce.

Greenhouse gas emissions from shale gas are predominantly down to two things: carbon dioxide produced when the gas is burned, and methane that leaks out while the well is being exploited.

This seasonally undulating record of carbon dioxide's inexorable rise over the past 50 years goes a long way towards explaining why 190 countries have seen fit to gather now in Copenhagen.

But rotting plant matter returns carbon dioxide to the atmosphere.

The lungs expel carbon dioxide when we exhale.

The mangrove forest also sequesters carbon dioxide in its root system.

Swedish researchers have shown that carbon retention by sediment is highly temperature-sensitive and that a warmer climate would result in increased carbon dioxide emissions to the atmosphere.

Then there is the problem of storing the carbon dioxide, which is at some level an inherently local issue.

The team predicts that further increases in carbon dioxide will halve the amount of water lost to the atmosphere.

They are working in his fields, helping convert another small patch of peatland, and adding to Indonesia’s alarming emissions of carbon dioxide.

The researchers next want to look into what happens when engineers inject liquid carbon dioxide from power plants deep underground, in an attempt to keep the carbon from entering the atmosphere.

It was long believed you yawned when there was too much carbon dioxide and not enough oxygen in your blood. A part of your brain called the brain stem detected this and triggered the yawn reflex.

Green plants synthesize carbohydrates from carbon dioxide and water.

Green plants capture carbon dioxide through photosynthesis and store carbon in their tissues.

Like carbon dioxide, black carbon absorbs sunlight and infrared radiation, trapping heat in the atmosphere — including the boundary layer closest to Earth's surface.

Today the copious carbon dioxide emitted to the atmosphere is left for nature to pick up, which it cannot do fast enough.

The engine would use at least 25% less fuel and, he claims, its emissions of carbon dioxide and nitrogen oxide would be cut by three-quarters because of its unique ignition properties.

Although eruptions do emit greenhouse gases such as carbon dioxide, volcanoes also spew sulfur dioxide.

The fact that the OMEGA process would clean up wastewater and help sequester carbon dioxide doesn't hurt, either.

A car with a natural gas-powered internal-combustion engine emits87 per cent less nitrogen oxide,70 per cent less carbon monoxide and25 less carbon dioxide than a car with an engine that uses petrol, according to research by the Honda Motor Co.

Oppenheimer feels more urgency than ever to deal with climate change, but he says that in the end, setting acceptable limits for carbon dioxide is a judgment call.

And then we have gas cooled reactors which can use supercritical carbon dioxide or helium.
