Not exact matches

2016 experienced the earliest melt, the latest onset of snow in autumn, and the longest snow - free season in 115 years of record - keeping — about 45 percent longer than the average over the previous four decades.

During a record melting jag this past summer, the Greenland ice sheet lost 552 billion tons (19 billion tons lower than the previous low), and the volume of sea ice fell to half the volume it had four years ago.

Greenland's ice sheet melted nearly 19 billion tons more than the previous high mark, and the volume of Arctic sea ice at summer's end was half what it was just four years ago, according to new NASA satellite data obtained by the Associated Press (AP).

In a study out of the University of Arizona, researchers found that melting ice sheets had a greater impact on sea level rise than the thermal expansion of the oceans during the previous interglacial period 125,000 years ago.

If significant area becomes an ablation zone, then once the previous winters snow has melted, the surface is composed of old ice, which every year becomes older than the last.

Satellite observations of the Greenland ice sheet, which are made daily, have shown that the period when snow melted during 2006 was 10 days longer than the average for the previous 18 years.

A 7 °F increase since 1991 contributed to another record ice melting year, 10 % more than the previous one set in 2005.

The ice at the GISP2 site in central Greenland was only one ice age thick before they hit rock, (as opposed to Antarctica where the ice is more than 6 cycles 700,000 years thick) indicating that ALL the Central Greenland ice melted during the previous warming cycle (125,000 years ago).

The fact that this ice didn't melt during previous warm periods does not, by itself, provide evidence that it is warmer now than at any time in the past 44,000 years, which is the implication of your comment.

For example, the melting of the Greenland ice sheet broke previous records in 2002, 2005, and 2007, and seasonal melting from 1996 to 2007 was above average compared with the 1973 - 2007 period.10, 11 The melting of the Greenland ice sheet contributed around 0.02 inch (0.6 millimeter) to global sea - level rise in 2005 — more than double the 1996 contribution.4 From 1993 to 2003 the average rate of sea - level rise increased to about 0.12 inches (3.1 millimeters) per year.12 That means that in 2005 Greenland could have contributed 19 percent of the average annual global sea level rise rate.

In addition, the enhanced detail of where and how much ice melted allowed the researchers to estimate that the annual acceleration in ice loss is much lower than previous research has suggested, roughly increasing by 8 billion tons every year.
