Sentences with phrase «permafrost loss»

According to the report, higher temperatures in Alaska from 1982 to 2014 caused increasing permafrost loss.

Achieving the ambitious Paris Agreement climate targets could limit permafrost loss.

The researchers, from Sweden and Norway as well as the UK, suggest that the huge permafrost losses could be averted if ambitious global climate targets are met.

«The ability to more accurately assess permafrost loss can hopefully feed into a greater understanding of the impact of global warming and potentially inform global warming policy.»

We should be paying close attention, since this positive feedback is linked to another, even more dangerous one (see «Tundra 4: Permafrost loss linked to Arctic sea ice loss»).

The study, carried out by a team of scientists from Sweden, Norway and the UK, is the first to work out what the ambitious targets contained in the Paris Agreement mean for permafrost loss.

This is because converting permafrost loss into carbon emissions is far from trivial, says Prof Pierre Friedlingstein, a professor of global carbon cycling at the University of Exeter and co-author on the new research.

Some of the projected impacts of climate change on the Arctic region include: damage to infrastructure from permafrost loss and changes in precipitation patterns, spatial shifts and changes to the productivity of marine organisms due to changes in ocean conditions and sea ice, reduced food security for some Arctic communities and impacts on Arctic and sub-Arctic marine mammals, especially those that depend on sea ice.

The USGS model also underestimates the extent of permafrost loss by the end of the century, he said, adding that his research shows two - thirds of the state's permafrost could be lost by 2100 if human carbon emissions aren't cut.

The increasing permafrost loss has caused a jump in the annual pulse of naturally occurring sulfates in the Yukon River.

Lead author Sarah Chadburn, associate research fellow at the University of Exeter, says: «Achieving the ambitious Paris Agreement climate targets could limit permafrost loss.

The researchers suggest that the huge permafrost losses could be averted if ambitious global climate targets are met.

«The ability to more accurately assess permafrost loss can hopefully feed into a greater understanding of the impact of global warming and potentially inform global warming policy.»

A 2008 study led by David Lawrence of the National Center for Atmospheric Research (NCAR) concluded (see «Tundra 4: Permafrost loss linked to Arctic sea ice loss»):

In the high emission scenario, or essentially no change in current trends of fossil fuel use, permafrost losses were between 6 million and 16 million square kilometers, while soil carbon losses varied from 74 to 652 petagrams and occur mostly after 2100.

Toohey said the two studies strongly suggest that permafrost loss is leading to massive changes in hydrology within the Arctic and boreal forests that may have consequences for the carbon cycle, fish and wildlife habitat and other parts of the ecosystem.

A new report documents how the effects of global warming, such as sea ice and permafrost loss, cascade throughout the ecosystem

Co-author Dr Eleanor Burke, from the Met Office Hadley Centre, said: «The advantage of our approach is that permafrost loss can be estimated for any policy - relevant global warming scenario.

Another of the co-authors, Dr Eleanor Burke, permafrost research scientist at the Met Office Hadley Centre, says: «The advantage of our approach is that permafrost loss can be estimated for any policy - relevant global warming scenario.

Permafrost loss will be significant, with consequent methane feedback creating further warming.
