Record Ice loss for Greenland’s Mittivakkat Glacier

Greenland’s glaciers keep shrinking as higher surface temperatures have created record mass losses in 2010 and 2011, researchers announced this week. “Our fieldwork results are a key indication of the rapid changes now being seen in and around Greenland, which are evident not just on this glacier but also on many surrounding small glaciers,” study [...]

Melting ice sheets now largest contributor to sea level rise

The Greenland and Antarctic ice sheets are losing mass at an accelerating pace, according to a new study. The findings of the study – the longest to date of changes in polar ice sheet mass – suggest these ice sheets are overtaking ice loss from Earth’s mountain glaciers and ice caps to become the dominant [...]

Ice sheets melting faster than expected

Greenland and Antarctica’s ice sheets are shrinking more quickly, suggesting United Nations projections for sea-level rise are too conservative, a U.S. National Aeronautics and Space Administration-funded study said.From 1992 to 2009, the two regions lost on average 36.3 billion tons more ice every year than the previous year, scientists led by Eric Rignot at NASA’s [...]

Record Melting in Greenland during 2010

2010 was an exceptional year for Greenland’s ice cap. Melting started early and stretched later in the year than usual. Little snow fell to replenish the losses. By the end of the season, much of southern Greenland had set a new record, with melting that lasted 50 days longer than average. This image was assembled [...]

New record melt for Greenland Ice Sheet: 50 days longer than average

New research shows that 2010 set new records for the melting of the Greenland Ice Sheet, expected to be a major contributor to projected sea level rises in coming decades. “This past melt season was exceptional, with melting in some areas stretching up to 50 days longer than average,” said Dr. Marco Tedesco, director of [...]

Record 2010 ice melt in Greenland, trend accelerating

Greenland’s icesheet, feared as a major driver of rising sea levels, shed a record amount of melted snow and ice in 2010, scientists reported Friday, a day after the UN said last year was the warmest on record. The 2010 runoff was more than twice the average annual loss in Greenland over the previous three [...]

Greenland iceberg quakes increase three-fold

Two seismologists, Meredith Nettles and Göran Ekström of Columbia University, discovered a few years ago that unusual earthquakes were emanating from the Greenland glaciers as they dumped the extra ice into the sea. “It’s remarkable that an iceberg can do this, but when that loss of ice occurs, it does generate a signal that sets [...]

Greenland ice now melting twice as fast

…in 2010, Greenland temperatures were the hottest on record. It also experienced record setting ice loss by melting. This ice loss is reflected in the latest data from the GRACE satellites which measure the change in gravity around the Greenland ice sheet. The ice sheet has been steadily losing ice and the rate of ice [...]

Greenland ice drips away at record speed

Meltdown in Greenland: inland ice drips away at record speed New calculations show that the amount of melted inland ice in Greenland is 25-50% higher in 2010 than normally New calculations show that the amount of melting inland ice in Greenland is 25-50% higher in 2010 than normally, reports professional journal Ingeniøren (The Engineer). The [...]

Greenland ice sheet melting at record rate

Greenland climate in 2010 is marked by record-setting high air temperatures, ice loss by melting, and marine-terminating glacier area loss. Summer seasonal average (June-August) air temperatures around Greenland were 0.6 to 2.4°C above the 1971-2000 baseline and were highest in the west. A combination of a warm and dry 2009-2010 winter and the very warm [...]
