Operation IceBridge Continues Critical Survey Of Antarctica's Changing Ice
2011-10-14 04:26:31

Scientists with NASA's Operation IceBridge airborne research campaign began the mission's third year of surveys this week over the changing ice of Antarctica. Researchers are flying a suite of scientific instruments on two planes from a base of operations in Punta Arenas, Chile: a DC-8 operated by NASA and a Gulfstream V (G-V) operated by the National Science Foundation and the National Center for Atmospheric Research. The G-V will fly through early November. The DC-8, which completed its...

California Coast To Feel Brunt Of Sea Level Rise
2011-09-14 10:51:12

  Picturesque beach towns up and down the coast of California may be facing hefty economic losses caused by rising ocean levels in the next century, according to a new state-commissioned study funded by the California Department of Boating and Waterways and conducted by economists at San Francisco State University. The study examines the cost of both coastal storm damage and erosion which are expected to increase as average coastal sea levels rise. Economists also expect impacts on...

Sea levels, erosion top public concerns Europeans face greater risk of illness, property damage and job losses because of the impacts of climate change on the seas around them. Worried citizens, whose biggest related top-of-mind concerns are sea level rise and coastal erosion, are taking personal actions to reduce carbon emissions. However, they largely blame climate change on other groups of people or nations and assign governments and industry responsibility for mitigating the problem...

Image 1 - New Coral Dating Method Gives Hints Of Possible Future Sea-level Changes

  New evidence of sea-level oscillations during a warm period that started about 125,000 years ago raises the possibility of a similar scenario if the planet continues its more recent warming trend, says a research team led by the Woods Hole Oceanographic Institution (WHOI). In a paper published online in the Sept. 11 Nature Geoscience, the researchers report data from an improved method of dating fossil coral reef skeletons in the Bahamas. By calculating more accurate ages for the...

An international team of scientists, led by Dr Stephen Barker of Cardiff University, has produced a prediction of what climate records from Greenland might look like over the last 800,000 years. Drill cores taken from Greenland's vast ice sheets provided the first clue that Earth's climate is capable of very rapid transitions and have led to vigorous scientific investigation into the possible causes of abrupt climate change. Such evidence comes from the accumulation of layers of ancient...

  An Update from NASA's Sea Level Sentinels: Like mercury in a thermometer, ocean waters expand as they warm. This, along with melting glaciers and ice sheets in Greenland and Antarctica, drives sea levels higher over the long term. For the past 18 years, the U.S./French Jason-1, Jason-2 and Topex/Poseidon spacecraft have been monitoring the gradual rise of the world's ocean in response to global warming. While the rise of the global ocean has been remarkably steady for most of...

NASA researchers have created the first complete map of the speed and direction of ice flow in Antarctica. The space agency said the map will be critical for tracking future sea-level increases from climate change. The researchers created the map using integrated radar observations from a consortium of international satellites. "This is like seeing a map of all the oceans' currents for the first time. It's a game changer for glaciology," Eric Rignot of NASA's Jet Propulsion Laboratory in...

WASHINGTON, Aug. 18, 2011 /PRNewswire-USNewswire/ -- NASA-funded researchers have created the first complete map of the speed and direction of ice flow in Antarctica. The map, which shows glaciers flowing thousands of miles from the continent's deep interior to its coast, will be critical for tracking future sea-level increases from climate change. The team created the map using integrated radar observations from a consortium of international satellites. (Logo:...

Bt Jill Sakai, University of Wisconsin-Madison During the last prolonged warm spell on Earth, the oceans were at least four meters "“ and possibly as much as 6.5 meters, or about 20 feet "“ higher than they are now. Where did all that extra water come from? Mainly from melting ice sheets on Greenland and Antarctica, and many scientists, including University of Wisconsin-Madison geoscience assistant professor Anders Carlson, have expected that Greenland was the main culprit. But...

Current Sea Level Rise
2013-04-01 10:39:21

The sea levels all around the world are rising. Current sea-level rise has the potential to affect human populations and the natural environment. Two key factors have contributed to the observed sea level rise. The first is thermal expansion: as the ocean water warms, it expands. The second is from the influence of land-based ice because of increased melting. The major store of water on land is found in the glaciers and the ice sheets. The rising of sea levels is one of several lines of...
