They are also failing to cut their own emissions of climate-warming greenhouse gases, the study found.

Australia has not abandoned its commitment to reducing climate-warming emissions.

Obama has said he wants a so-called cap and trade system that would put a price on emissions of climate-warming carbon.

Australia, Canada and America also pumped out more climate-warming gases.

This will alarm scientists who last week demanded urgent cuts in climate-warming emissions.

China is amongst the world's top emitters of climate-warming greenhouse gases.

But around the world, nations under pressure to reduce the production of climate-warming gases are turning to low-emission nuclear energy as never before.

Washington also opposes mandatory limits on climate-warming greenhouse emissions.

But it can lead to soil erosion and cuts down on trees' ability to lock up climate-warming carbon dioxide.

Bush has opposed economy-wide limits on the emission of climate-warming carbon dioxide.

Even though the cars themselves emit no climate-warming greenhouse gases, the manufacture of their fuel does.

Each fat person is said to be responsible for emitting a ton more of climate-warming carbon dioxide per year than a thin one.

He reports on a new “voluntary carbon standard” intended by its developers to increase confidence that a ton of avoided climate-warming emissions is real.

It is the most potent climate-warming aerosol.

Environmentalists say trains emit less climate-warming carbon dioxide and that planes are 10 times more damaging.

The Bush administration has consistently opposed economy-wide measures to limit climate-warming emissions of carbon dioxide.

Butcher said the key to combatting global warming is to pass a law to cap and trade climate-warming greenhouse emissions.

He claims that over the increasing part of the solar cycle the Sun has the same climate-warming effect as increasing greenhouse gases.

An analysis of the plant material suggests there was a rapid and dramatic rise in climate-warming carbon compounds in the atmosphere.

It said a main reason to use alternative fuels for transportation is to cut climate-warming greenhouse gas emissions created by burning fossil fuel.

The burning of fossil fuels also sends climate-warming carbon dioxide into the atmosphere, contributing to global warming.

Some new stoves, for instance, can cut fuel use by 30-60 percent, while reducing air pollution exposure and climate-warming pollution.

"And you simply won't get the impact of the reductions (in climate-warming carbon dioxide emissions) you need unless you do it."

Methane is a potent greenhouse gas, with as much as 25 times the climate-warming potential as carbon dioxide.

Congress should consider putting a price on climate-warming carbon emissions, Obama said, briefly nodding to his failed, first-term plan to confront climate change.
