Sentences with phrase «average ice loss rate»

Not exact matches

The team also compared the ice loss up until the mid-1980s to that observed by satellites over roughly the last decade and found that today the rate of ice loss is twice the 20th century average, mostly because of increased water runoff from the ice sheet's surface.

For Greenland to lose 285,000 km ³ of ice in 89 years, the AVERAGE rate of loss would have to be more than 3,200 km ³ / yr, or nearly 12 times faster than the current loss rate (273 km ³ / yr).

However, despite near normal rates of ice loss during the month, June 2015 was a relatively warm month (Figure 7) with 925 hPa air temperatures up to 2.5 C higher than average near the North Pole and East Siberian Sea, with even warmer air temperatures in the Kara Sea (up to 4.5 C).

The resulting enhanced loss of summer and winter sea ice resulted in feedbacks, associated with Arctic Amplification, which has raised Arctic air temperatures at a rate twice the global average.

As reported in Remote Sensing of Environment, from 1953 to 2010, the average rate of ice surface loss was 18 centimeters (7.1 inches) per year.

This is a decrease from the average rate of ice loss for June 2010 of -85,210 square kilometers per day, and is slower than climatology (average of -84,050 square kilometers per day for 1979 - 2000).

From July 1 - July 20, the rate of ice loss averaged -79,810 square kilometers per day.

In stark contrast to the relatively slow ice loss during June, July saw quite rapid ice loss (Figure 6), with rates averaging over 100,000 km2 per day through the month.

Fluctuations in the mass of the Greenland and Antarctic ice sheets are of considerable societal importance as they impact directly on global sea levels: since 1901, ice losses from Antarctica and Greenland, alongside the melting of small glaciers and ice caps and thermal expansion of the oceans, have caused global sea levels to rise at an average rate of 1.7 mm / yr.

The rate of ice loss during July 2016 was slightly below average at 83,800 square kilometers (32,400 square miles) per day.

The Concordia Dome ice core turns out to average about 0.43 cm of ice per year, so the loss of resolution of atmospheric CO2 by diffusion averaging is about twice the rate of Vostok.

New data from the National Snow and Ice Data Center shows that the average Arctic sea ice extent in July set a new monthly record low — even though the rate of ice loss slowed «substantially» in the last two weeks of the monIce Data Center shows that the average Arctic sea ice extent in July set a new monthly record low — even though the rate of ice loss slowed «substantially» in the last two weeks of the monice extent in July set a new monthly record low — even though the rate of ice loss slowed «substantially» in the last two weeks of the monice loss slowed «substantially» in the last two weeks of the month.

Using a simple elastic model, we estimate that western Greenland's ice loss is accelerating at an average rate of 8.7 ± 3.5 Gt yr − 2, whereas the rate for southeastern Greenland — based on limited data — falls at 12.5 ± 5.5 Gt yr − 2.

We can estimate the potential magnitude of the ice mass biases by noting that if the average velocity prediction bias of ~ 5 mm / yr evident in Figure 5 is developed over ~ 2 × 10 ^ 6 km2, an area somewhat smaller than that of West Antarctica, this would cause an apparent but spurious ice loss of ~ 33 Gt yr - 1, which is a significant fraction of all published ice mass rates derived from GRACE [Velicogna and Wahr, 2006; Chen et al., 2006; Ramillien et al., 2006; Sasgen et al., 2007a].

On average the daily ice loss rate for the Arctic as a whole during August was -54,000 square million square kilometers per day, or about average.
