Sentences with phrase «recent ice loss rates»

The study found that, based on recent ice loss rates and the movement of the Thwaites Glacier in West Antarctica, as well as computer model projections, «early - stage collapse has begun.»

Not exact matches

From recent instrumental observations alone we are therefore unable to predict whether mass loss from these ice sheets will vary linearly with changes in the rate of sea - level rise, or if a non-linear response is more likely.

The reasonable agreement in recent years between the observed rate of sea level rise and the sum of thermal expansion and loss of land ice suggests an upper limit for the magnitude of change in land - based water storage, which is relatively poorly known.

We are seeing an increase in the recent speed of ice loss, when compared to the long - term ice - loss rate,» says lead researcher Whyjay Zheng, a doctoral student in geophysics at Cornell University.

This has likely delayed further ice loss in these areas, which together with the low SLP over the central Arctic Ocean, accounts in part for the recent decrease in the rate of ice loss seen in Figure 2.

Interestingly this year, while July ice loss rates were rapid in the central Arctic, melt out of the seasonal ice in Hudson and Baffin bays was slow with the ice cover persisting longer than in recent years.

Mass gains of the Antarctic ice sheet exceed losses Mass changes of the Antarctic ice sheet impact sea - level rise as climate changes, but recent rates have been uncertain.

«Second, in contrast to the previously reported slowing in the rate during the past two decades1, our corrected GMSL data set indicates an acceleration in sea - level rise (independent of the VLM used), which is of opposite sign to previous estimates and comparable to the accelerated loss of ice from Greenland and to recent projections, and larger than the twentieth - century acceleration.

The loss, in recent decades, of thousands of square miles of sea ice has accelerated warming in the Arctic, where temperatures are increasing at two to three times the rate of the globe as a whole.

Because of that uncertainty, the United Nations Intergovernmental Panel on Climate Change (IPCC)-- the international body that reviews and assesses the most recent peer - reviewed climate research from around the world — assumed in 2007 that the rate of ice loss from the poles wouldn't change much over the next century.

Contrary to the aforementioned report, a recent study by Gardelle and others (2012) reveals that high rates of ice loss can occur on debris - covered glacier tongues (12).

While the loss of glacier mass has continued for the past few decades with a slight increase in recent years, the rate of mass loss from the Greenland ice sheet has dramatically increased in the past decade and continues to increase.

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.»
