An international team of scientists has discovered that the last remaining stable portion of the Greenland ice sheet is stable no more.
The finding, which will likely boost estimates of expected global sea level rise in the future, appears in the March 16 issue of the journal Nature Climate

A recent study has indicated that the Jakobshavn Glacier in Greenland is experiencing a rapid melt that threatens to raise sea levels by up to one centimeter.
The glacier, which is thought to have yielded the iceberg that ended the Titanic's fated voyage, has begun to melt at an alarming rate, about four times faster than it was...

The first-ever study of air trapped in the deep snowpack of Greenland has yielded surprising results. Current computer models had predicted that levels of carbon monoxide locked into the snowpack would be higher than those recorded in the 1950s, yet it appears that the opposite is true.
A recent paper published in the journal...

The Greenland ice sheet is not only melting from above, but also from below. It has been discovered that this is caused by heat flowing up from Earth's mantle. It's variable across Greenland, absent in some places and intense in others. Last summer, NASA satellites revealed that the surface of Greenland's massive ice sheet had melted over an...

NASA satellites reveal that the surface of Greenland's massive ice sheet has melted this month over an unusually large area. NASA has been monitoring the Greenland melt for 30 years, and they're calling this one "unprecedented," partly because it's so large and also because it occurred at the COLDEST part of the country, Summit station....

While most glaciers are melting
at an alarming rate, one of them is growing bigger--ALSO as a result of climate change
. Hotter summers may actually slow down the melting rate of glaciers. Researchers have learned that...

Greenland's ice sheet, which could be a major cause of rising sea levels, melted at a record rate
in 2010. And a look at an ice field atop the highest mountain in the eastern European Alps suggests that the glacier may hold records of ancient climate extending back as much as a...

In winter, Greenland is dark for months and this year the first, brief sunrise was expected on January 13. Instead, the sun rose at 12:56 PM on January 11. The precise reason for this remains unknown. There is no apparent astronomical cause, as the constellations, the moon and the sun appear to be in their usual positions in relation to earth. One...

Part II - Is global warming yesterday's news? A typical solar minimum lasts close to 500 days, and occurs between the solar maximums, which happen every 11 years. However, we have now had a little over 700 days without sunspots in the current solar minimum. Researchers are worried that the melting of the Greenland ice sheet...
