Sentences with phrase «about glacier losses»

Not exact matches

Within a few years, the main outlet glacier draining the region — Zachariae Isstrom — retreated about 20 kilometers, and regional ice mass loss jumped from zero to roughly 10 metric gigatons a year.

The study fuels a growing concern among scientists about the factors affecting the Antarctic ice sheet — namely, that warm ocean waters are helping to melt glaciers and drive greater levels of ice loss, particularly in West Antarctica.

«If you haven't had proximity to these glaciers, if you haven't thought about where water comes from, it would be easy to understate or underestimate the implications of glacial ice loss in a state that has predominantly a semi-desert climate and certainly by contemporary climate models is going to be pretty significantly impacted by climate change,» said Jacki Klancher, a professor of environmental science at Central Wyoming College.

The team hope the study raises awareness about the rapid glacier loss in Bolivia, how it could change in the future, and how it could affect water supply and cause glacial lake outburst floods.

About a quarter of the average annual ice loss came from glaciers and ice caps outside of Greenland and Antarctica (roughly 148 billion tons, or 39 cubic miles).

However, the idea is simple, and I've talked about this much in many presentations this winter: Take the amount of ice you need to get rid of from Greenland to raise sea level 2 m in the next century, reduce it by your best estimate of the amount that would be removed by surface mass balance losses, and try to push the rest out of the aggregate cross-sectional area of Greenland's marine - based outlet glaciers.

The NY Times has a detailed article by Justin Gillis about the loss of ice from glaciers, principally in Greenland and the dearth of information about the ice loss as more and more satellites take the plunge.

While worries about rising sea levels are focused on the massive ice sheets of Greenland and Antarctica, the loss of small mountain glaciers comes with its own consequences.

Their projections show a reduction of about 70 % in glacier volume by the year 2100 compared to 2005, with the largest losses occurring around 2020 to 2040.

They find that all of the glaciers receded over the 1952 - 2005 period with an average loss in surface area of about 0.19 % per year.

Loss of glacial volume in Alaska and neighboring British Columbia, Canada, currently contributes 20 % to 30 % as much surplus freshwater to the oceans as does the Greenland Ice Sheet — about 40 to 70 gigatons per year, 66,78,63,57,64,58 comparable to 10 % of the annual discharge of the Mississippi River.79 Glaciers continue to respond to climate warming for years to decades after warming ceases, so ice loss is expected to continue, even if air temperatures were to remain at current levLoss of glacial volume in Alaska and neighboring British Columbia, Canada, currently contributes 20 % to 30 % as much surplus freshwater to the oceans as does the Greenland Ice Sheet — about 40 to 70 gigatons per year, 66,78,63,57,64,58 comparable to 10 % of the annual discharge of the Mississippi River.79 Glaciers continue to respond to climate warming for years to decades after warming ceases, so ice loss is expected to continue, even if air temperatures were to remain at current levloss is expected to continue, even if air temperatures were to remain at current levels.

What the report says about Alaskan glaciers and climate change: The collective ice mass of all Arctic glaciers has decreased every year since 1984, with significant losses in Alaska.

In comparison, ice - mass loss from the ice - caps themselves (not the glaciers), uncertain as the calculations are, is thought about equal to the glacial melt.

But for scientists concerned about the impact of glacier melt, it is important to know whether these recent losses are due to natural variability, or to man - made climate change.

In 2002, the Larsen B ice shelf collapsed; in 2003, the World Glacial Monitoring Service reported that «The recent increase in the rates of ice loss over reduced glacier surface areas as compared with earlier losses related to larger surface areas (cf. the thorough revision of available data by Dyurgerov, 2002) becomes even more pronounced and leaves no doubt about the accelerating change in climatic conditions.»

Lead author Adrian Jenkins said, The discovery of the ridge has raised new questions about whether the current loss of ice from Pine Island Glacier is caused by recent climate change or is a continution of a longer - term process that began when the glacier disconnect from the ridge.

What I do know is that all this [glacier loss] is taking place with only about one degree warming; not even quite one degree warming.
