Sentences with phrase «thawing permafrost accelerates»

The general consensus is thawing permafrost accelerates atmospheric warming by emitting methane that is many many times more potent in warming and most carbon is from man made pollution.

Countering a widely - held view that thawing permafrost accelerates atmospheric warming, a study published this week in the scientific journal Nature suggests arctic thermokarst lakes are «net climate coolers» when observed over longer, millennial, time scales.

Not exact matches

A team of researchers lead by Florida State University have found new evidence that permafrost thawing is releasing large quantities of greenhouse gases into the atmosphere via plants, which could accelerate warming trends.

«Permafrost thawing could accelerate global warming.»

They include, Obama said, the accelerated thawing of the frozen permafrost that sits beneath «the earth on which 100,000 Alaskans live, threatening homes [and] damaging transportation and energy infrastructure.»

With climate warming, permafrost thawing has accelerated, increasing the risk that a large portion of this carbon will be released into the atmosphere as greenhouse gases.

If we start out with a balanced system which contains frozen water at the poles, the mid to high latitudes begin to thaw, triggering soil greenhouse gas feedbacks (permafrost thaw and following oxic and anoxic sources add to the greenhouse gas budget), a chronic linear process (which helps to accelerate changes of the equilibrium state, reduces the ability of the atmosphere to break down greenhouse gases — less hydroxide radicals).

And we may yet see it accelerate due to positive feedbacks (e.g. release of methane as the permafrost thaws).

And as the permafrost thaws, it is releasing methane and carbon dioxide — potent greenhouse gases that scientists warn will accelerate climate change.

Permafrost is thawing at an accelerated pace due to rising air temperature and this degradation releases carbon dioxide and methane — two greenhouse gases that affect the amount of radiant energy that can reach or leave the Earth.

Carbon dioxide released by thawing permafrost in the Arctic is likely to accelerate climate change, even if it doesn't reach runaway conditions.

While anthropogenic warming should accelerate the thawing of offshore permafrost via warming of Arctic Ocean shelf waters, this impact should be considered additive to a broader thawing trend that has been underway for thousands of years.
