Antarctica Could Raise Sea Level Faster Than Previously Thought

Potsdam Institute for Climate Impact Research Ice discharge from Antarctica could contribute up to 37 centimeters to the global sea level rise within this century, a new study shows. For the first time, an international team of scientists...

Arctic Melt Ponds

Kate Ramsayer, NASA's Earth Science News Team Even from 65,000 feet above Earth, aquamarine melt ponds in the Arctic stand out against the white sea ice and ice sheets. These ponds form every summer, as snow that built up on the ice melts, creating crystal clear pools. On July 16 and July 17, NASA’s ER-2 aircraft flew above Alaskan glaciers and to the North Pole, carrying an instrument called the Multiple Altimeter Beam Experimental Lidar, or MABEL. MABEL is a laser altimeter,...

West Antarctic Ice Sheet
2014-07-12 06:07:29

redOrbit Staff & Wire Reports - Your Universe Online Much of the climate change-related research published recently has focused on the impact of warming temperatures on the West Antarctic ice sheet – but what is it about this region that causes scientists to be so interested in it? According to the US National Oceanic and Atmospheric Administration (NOAA), the West Antarctic ice sheet contains two major slabs of frozen water (the Ronne and Ross Ice Shelves), as well as several...

redOrbit Staff & Wire Reports - Your Universe Online Newly discovered massive blocks of ice located underneath the ice of Greenland could help scientists learn more about the behavior of ice sheets and how they will respond to global warming, according to research appearing in the latest edition of Nature Geoscience. Lead author Robin Bell, a geophysicist at Columbia University's Lamont-Doherty Earth Observatory, and her colleagues used ice-penetrating radar to discover the ragged...

West Antarctica's Thwaites Glacier Is Melting Due To Geothermal Heat
2014-06-10 10:18:21

Gerard LeBlond for redorbit.com - Your Universe Online Researchers from the Institute for Geophysics at The University of Texas at Austin (UTIG) have discovered that Thwaites Glacier is being eroded by the ocean, as well as being melted from geothermal heat. Their findings are published in the current edition of the Proceedings of the National Academy of Sciences (PNAS). Accurate information from beneath the West Antarctic Ice Sheet has previously been inaccessible, but new findings of...

Iron From Melting Ice Sheets Could Buffer Global Warming
2014-05-21 03:19:14

University of Bristol A newly-discovered source of oceanic bioavailable iron could have a major impact on our understanding of marine food chains and global warming. A UK team, including researchers from the University of Bristol, has found that summer meltwaters from ice sheets are rich in iron, which will have important implications on phytoplankton growth. Their findings are reported today in Nature Communications. It is well known that bioavailable iron boosts phytoplankton growth...

Greenland ice sheet

April Flowers for redOrbit.com - Your Universe Online In 1889 and 2012, there was large-scale melting of the Greenland ice sheet. Scientists have assumed these events were driven by warming alone, but a new study from the Thayer School of Engineering at Dartmouth College and the Desert Research Institute reveals that rising temperatures and ash from Northern Hemisphere forest fires combined to cause the ice melting events. The findings, published in the Proceedings of the National...

WASHINGTON, May 19, 2014 /PRNewswire-USNewswire/ -- Scientists at NASA and the University of California, Irvine (UCI), have found that canyons under Greenland's ocean-feeding glaciers are deeper and longer than previously thought, increasing the amount of Greenland's estimated contribution to future sea level rise. http://photos.prnewswire.com/prnvar/20081007/38461LOGO "The glaciers of Greenland are likely to retreat faster and farther inland than anticipated, and for much longer,...

University of California - Irvine Major UCI-NASA work reveals long, deep valleys connecting ice cap to the ocean Greenland's icy reaches are far more vulnerable to warm ocean waters from climate change than had been thought, according to new research by UC Irvine and NASA glaciologists. The work, published May 18 in Nature Geoscience, shows previously uncharted deep valleys stretching for dozens of miles under the Greenland Ice Sheet. The bedrock canyons sit well below sea level,...

Word of the Day
endocarp
  • The hard inner (usually woody) layer of the pericarp of some fruits (as peaches or plums or cherries or olives) that contains the seed.
This word comes from the Greek 'endon,' in, within, plus the Greek 'karpos', fruit.
