Sentences with phrase «greenhouse warming of the atmosphere»

I've never challenged the notion that, if it exists, greenhouse warming of the atmosphere could lead to more heat being RETAINED by the oceans, which is not nearly the same thing as a DIRECT transfer of heat energy FROM the atmosphere, TO the oceans.

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.

It may seem surprising to people, but you can look at something like Mars, which has a very thin atmosphere, and you can look at something like Venus which we tend to think of as sort of having this rather heavy, clouded atmosphere, which [is] hellishly warm because of runaway greenhouse effect, and on both of those planets you are seeing this phenomenon of the atmosphere leaking away, is actually what directly has led to those very different outcomes for those planets; the specifics of what happened as the atmosphere started to go in each case [made] all the difference.

«As the climate gets warmer, the thawing permafrost not only enables the release of more greenhouse gases to the atmosphere, but our study shows that it also allows much more mineral - laden and nutrient - rich water to be transported to rivers, groundwater and eventually the Arctic Ocean,» explained Ryan Toohey, a researcher at the Interior Department's Alaska Climate Science Center in Anchorage and the lead author of the study.

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.

The greenhouse effect is the process in which the emission of infrared radiation by the atmosphere warms a planet's surface.

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.

It's not clear how much of a greenhouse effect that would produce, but it's a good bet that Earth would be a lot warmer — much as it would be, say, if there were no plants drawing carbon dioxide out of the atmosphere.

Although there is much less of it in the air, it is 33 times more effective than carbon dioxide at trapping heat in the atmosphere and adding to greenhouse warming.

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.

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.

According to the accepted view, the formation of the Earth released vast amounts of water vapour and carbon dioxide, which formed a thick atmosphere and caused strong greenhouse warming at a time when the Sun was 15 to 20 per cent fainter than today.

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.

It will spur clean energy investments and more energy - efficient technologies by doing so, and right now, carbon dioxide — the main man - made greenhouse gas warming the atmosphere — is the only type of greenhouse gas capped in the Chinese program.

Increased cooling means increased consumption of electrical power and therefore higher emissions of greenhouse gases into the atmosphere, driving global warming even faster.
