Earth's heat adds to climate change to melt Greenland ice

Scientists have discovered what they think may be another reason why Greenland's ice is melting: a thin spot in Earth's crust is enabling underground magma to heat the ice. They have found at least one "hotspot" in the northeast corner of Greenland -- just below a site where an ice stream was recently discovered.

1. NASA provides new perspectives on the earth's changing ice sheets
   12-11-2006 · EurekAlert!
   It is widely documented that climate change is causing the Greenland and Antarctic ice sheets to shrink. What most do not know is that until just six years ago, we had no real way of measuring whether the ice sheets were shrinking or growing, or at what rate. Waleed Abdalati of NASA's Goddard Space Flight Center, provides an overview of recent findings at the American Geophysical Union meeting, December 11 at 7:15 p.m. EST (session C14B-02).

2. Melting of the Greenland ice cap may have consequences for climatic change
   05-07-2007 · EurekAlert!
   At the last ice age, before the great ice sheets of the Arctic Ocean began to melt, early sporadic episodes of melting of the old ice sheet which covered the British Isles had already begun to affect the circulation of the ocean currents. Based on this observation, scientists consider that the acceleration of the melting of the Greenland ice cap could play an important role in the development of climate change.

   02-11-2008 · EurekAlert!
   A comprehensive new study authored by University at Buffalo scientists and their colleagues for the first time documents in detail the dynamics of parts of Greenland's ice sheet, important data that have long been missing from the ice sheet models on which projections about sea level rise and global warming are based.

6. NASA mission checks health of Greenland's ice sheet and glaciers
   05-30-2007 · EurekAlert!
   A NASA-led research team has returned from Greenland after an annual three-week mission to check the health of its glaciers and ice sheet. About 82 percent of Greenland is made up of a giant ice sheet. During the Arctic Ice Mapping Project, researchers measured critical areas of the island's ice sheet as well as its glaciers and monitored changes that may be connected to global climate change.

7. Researchers Link Ice Age Climate-change Records To Ocean Salinity
   10-07-2006 · ScienceDaily
   Sudden decreases in temperature over Greenland and tropical rainfall patterns during the last Ice Age have been linked for the first time to rapid changes in the salinity of the north Atlantic Ocean, according to research published Oct. 5, 2006, in the journal Nature.

8. European lead in reading past climates from ice cores
   10-11-2007 · EurekAlert!
   Climate change is a reality today, but how can we find out about the future dangers it poses? What we really need is a full record of the Earth's climate for several hundred thousand years, complete with samples of air from different epochs that can be taken to the lab for analysis. Incredibly, this record exists, in the icecaps of the Arctic and Antarctic regions, and a European Science Foundation program has a key role in deciphering it.

9. Evidence From Ice Age That Climate Change Can Have A Rapid Effect On Ocean Circulation
   10-09-2006 · ScienceDaily
   Sudden shifts in temperature over Greenland and tropical rainfall patterns during the last ice age have been linked for the first time to rapid changes in the salinity of the north Atlantic Ocean. The results provide further evidence that climate change can have a direct and rapid impact on ocean circulation and chemistry.

10. Exploration of lake hidden beneath Antarctica's ice sheet begins
    01-15-2008 · EurekAlert!
    A four-man science team led by British Antarctic Survey's Dr Andy Smith has begun exploring an ancient lake hidden deep beneath Antarctica's ice sheet. The lake -- the size of Lake Windermere -- could yield vital clues to life on Earth, climate change and future sea-level rise.
