Rising Sea Levels Will Require Adaptation For Generations To Come
2013-07-17 05:46:24

Susan Bowen for redOrbit.com - Your Universe Online Current levels of greenhouse gas emissions will have far-reaching effects, even if the levels decrease in the near future. According to a new study published in the Proceedings of the National Academy of Sciences, the greenhouse gases emitted today will cause the sea level to rise for centuries to come. It is estimated each degree of global warming will raise sea levels by more than two meters. Anders Levermann, lead author of the...

Satellite Data Not Enough Predict Ice Cap Melt
2013-07-15 09:38:00

Brett Smith for redOrbit.com - Your Universe Online New research from a team of European scientists has found there is not enough satellite data to determine the rate of polar ice cap melt very far into the future and warned against using current trends to predict sea level rise that might result from melting glaciers. The ice sheets on Greenland and Antarctica represent the biggest potential contributor to sea level rise. According to a study published last year including data from...

Surface Melt Will Continue To Dominate Greenland Ice-Loss
2013-07-10 15:13:45

Lee Rannals for redOrbit.com - Your Universe Online According to research published in the Journal of Glaciology, surface ice melt will be the dominant process controlling ice-loss from Greenland. Greenland's ice sheet is considered an important potential contributor to future global sea-level rise over the next century or longer. It contains an amount of ice that could lead to a rise of global sea-level by more than 22 feet if it completely melted. Changes in its total mass are caused...

Alaska´s melting glaciers remain one of the largest contributors to the world´s rising sea levels, say two University of Alaska Fairbanks geophysicists. UAF Geophysical Institute researchers Anthony Arendt and Regine Hock joined 14 scientists from 10 countries who combined data from field measurements and satellites to get the most complete global picture to date of glacier mass losses and their contribution to rising sea levels. “Sea level change is a pressing societal...

Melting Glaciers Contributing Significantly To Sea Rise
2013-05-17 09:49:29

April Flowers for redOrbit.com - Your Universe Online Scientists have known for some time that melting glaciers are contributing to the global sea-level rise. However, the amount being contributed by each region of the planet has never before been calculated with the accuracy of a new study led by researchers at the University of Colorado at Boulder and Clark University. Ninety-nine percent of Earth´s land ice is locked up in the Greenland and Antarctica ice sheets. The study,...

Antarctic Glacial Melt May Be Natural
2013-04-15 11:05:27

Brett Smith for redOrbit.com - Your Universe Online As the debate over climate change continues, so does the publication of studies that support or challenge the notion that human activity is the main driver of rising temperatures. According to a new study in“¯Nature Geoscience, the dramatic thinning of glaciers in Western Antarctica is due to natural variation, and cannot be attributed directly to carbon emissions. "If we could look back at this region of Antarctica in...

Warming Oceans May Be Driving Sea-Ice Expansion In Antarctica
2013-04-01 07:07:28

Lawrence LeBlond for redOrbit.com - Your Universe Online A growing number of studies have pegged global warming and climate change as a cause of sea-ice decline in recent decades. However, a newly published study in the journal Nature Geoscience is showing a vastly different scenario. According to researchers at the Royal Netherlands Meteorological Institute (KNMI), ocean warming may actually be driving sea-ice expansion in the Antarctic. While sea ice at the North Pole has shrunk...

Greenland's Peripheral Glaciers Also Contribute Significantly To Sea-Level Rise
2013-03-18 13:39:33

Alan McStravick for redOrbit.com - Your Universe Online The oft-cliché idea behind the naming of Iceland and Greenland claims their names were derived in an attempt to fool would be sailing marauders, attracting them to the desolate but more hospitably named Greenland, leaving the citizens of Iceland to live upon their slightly more lush island without threat of invasion. In fact, Erik the Red, it is believed, gave the moniker to attract settlers to the ice covered island...


Word of the Day
call-note
  • The call or cry of a bird or other animal to its mate or its young.
'Call-note' is newer than 'bird-call,' which originally referred to 'an instrument for imitating the note of birds' but now also refers to 'the song or cry of a bird.'
