  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...

Melting ice sheets contributed much more to rising sea levels than thermal expansion of warming ocean waters during the Last Interglacial Period, a UA-led team of researchers has found By Daniel Stolte, University of Arizona Thermal expansion of seawater contributed only slightly to rising sea levels compared to melting ice sheets during the Last Interglacial Period, a University of Arizona-led team of researchers has found. The study combined paleoclimate records with computer simulations of...

Study on Jakobshavn Isbrae supports growing evidence that calving glaciers are particularly sensitive to climate change Large, marine-calving glaciers have the ability not only to shrink rapidly in response to global warming, but to grow at a remarkable pace during periods of global cooling, according to University at Buffalo geologists working in Greenland. The conclusion stems from new research on Jakobshavn Isbrae, a tongue of ice extending out to sea from Greenland's west coast. Through...

According to the National Oceanic and Atmospheric Administration (NOAA), coastal communities along the U.S. East Coast could be at risk to higher sea levels and more destructive storm surges in future El Nino years. NOAA's new study examined water levels and storm surge events during the "cool season" of October to April for the past five decades at four sites. The study found that strong El Nino years caused the East Cost to have three times the average number of storm surge events. ...

Fresh research into glaciers could help scientists better predict the impact of changing climates on global sea levels Fresh research into glaciers could help scientists better predict the impact of changing climates on global sea levels. Scientists have shown for the first time that the terrain beneath glaciers influences how much glacier melt contributes to fluctuations in sea levels. Researchers say the study will improve their understanding of how ice sheet movements have affected sea...

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...
