The mounting evidence for climate change, and all its tragic consequences, has provided a powerful argument against fossil fuel power stations: the burning of coal, gas and oil releases carbon dioxide into the atmosphere and this is almost certainly responsible for global warming.

Whether it is the sprawl of deserts or the loss of tropical forests as the world's poor cut trees for firewood and clear land for agriculture, or the ineluctable warming of the planet as vehicles and factories deposit millions of tons of greenhouse gases into the atmosphere, «economic pressures lie behind them all» (Tolba 1991, p. 10).

The main cause of climate change is greenhouse gas emissions from fossil fuels (coal, oil and natural gas), which trap heat in the atmosphere and warm the planet.

It's no mystery why carbon dioxide (CO2) levels fluctuate with the seasons: As greenery grows in the spring and summer, it soaks up the planet - warming gas, and when trees shed their leaves in the autumn, some of that gas returns to the atmosphere.

«Although most of the macrophyte carbon is released back to the atmosphere in the same form that it is assimilated, carbon dioxide, some of it is actually exported to the ocean as dissolved carbon or released to the atmosphere as methane, a gas that has a warming potential 20 times larger than carbon dioxide,» said John Melack, a professor at the University of California, Santa Barbara.

This means that the science of climate change may partially undergo a shift of its own, moving from trying to prove it is a problem (it is now «very likely» that greenhouse gases in the atmosphere have already caused enough warming to trigger stronger droughts, heat waves, more and bigger forest fires and more extreme storms and flooding) to figuring out ways to fix it.

Instead of piping in natural CO2, it will use the greenhouse gas captured at a coal - fired power plant just completed nearly 100 miles north of here and send it down into the reservoir, pushing oil out and leaving the greenhouse gas deep below, safely locked away from the atmosphere, so it does not add to global warming.

Warmer oceans are thawing methane deposits, adding more of the greenhouse gas to the atmosphere

All the greenhouse gases absorb infrared, and they also release the infrared, so these act as blockades to the infrared, leaving the atmosphere and going off into space; and the Earth warms up to send off even more infrared from the surface in order to reach its state, sort of a steady state with regard to space.

Higher lake temperatures may speed the conversion of carbon - rich organic matter in lake sediments into methane and carbon dioxide, gases that once released into the atmosphere could exacerbate global warming.

While a strong El Niño provided a boost to global temperatures last year, the main driver of the planet's temperature surge, as well as other climate trends, is the warming caused by the buildup of greenhouse gases in the atmosphere.

A few of the main points of the third assessment report issued in 2001 include: An increasing body of observations gives a collective picture of a warming world and other changes in the climate system; emissions of greenhouse gases and aerosols due to human activities continue to alter the atmosphere in ways that are expected to affect the climate; confidence in the ability of models to project future climate has increased; and there is new and stronger evidence that most of the warming observed over the last 50 years is attributable to human activities.

Warming of arctic soils and thawing of permafrost thus can have substantial consequences for the global climate, as the large C and N stores could be released to the atmosphere as the greenhouse gases carbon dioxide (CO2), methane (CH4) and nitrous oxide (N2O).

Already, the planet's average temperature has warmed by 0.7 degree C, which is «very likely» (greater than 90 percent certain) to be a result of the rising concentrations of greenhouse gases in the atmosphere, according to the U.N. Intergovernmental Panel on Climate Change.

It increases the ability to predict how changes in land use or climate warming could affect the sources and global concentrations of greenhouse gases in the atmosphere.

A surprising recent rise in atmospheric methane likely stems from wetland emissions, suggesting that much more of the potent greenhouse gas will be pumped into the atmosphere as northern wetlands continue to thaw and tropical ones to warm, according to a new international study led by a University of Guelph researcher.

And those feedbacks ultimately determine the extent to which that initial warming will be amplified, but they don't even change the fact that you elevate greenhouse gas concentrations in the atmosphere and you'll get a warming of the surface.

The area boasts the world's warmest ocean temperatures and vents massive volumes of warm gases from the surface high into the atmosphere, which may shape global climate and air chemistry enough to impact billions of people worldwide.

This year has already brought higher temperatures than normal nation - wide, and that trend is expected to continue, in part due to global warming which is caused by rising concentrations of greenhouse gases in the atmosphere.

The warm waters in this area feed thunderstorms with heat and moisture, which loft all sorts of gases above the lowest layer of atmosphere, known as the troposphere, into the stratosphere.

From the basic physics of the atmosphere, scientists expect that as the planet heats up from ever - mounting levels of greenhouse gases, net global precipitation will increase because a warmer atmosphere holds more moisture.

Yet despite all the complexities, a firm and ever - growing body of evidence points to a clear picture: the world is warming, this warming is due to human activity increasing levels of greenhouse gases in the atmosphere, and if emissions continue unabated the warming will too, with increasingly serious consequences.

The continual warming of the planet's atmosphere as heat - trapping greenhouse gases accumulate is also a factor.

By analyzing global water vapor and temperature satellite data for the lower atmosphere, Texas A&M University atmospheric scientist Andrew Dessler and his colleagues found that warming driven by carbon dioxide and other gases allowed the air to hold more moisture, increasing the amount of water vapor in the atmosphere.
