What goes down must come back up
(Phys.org)—For most of the past two decades, the NASA and European Topex/Poseidon, Jason-1 and Jason-2 satellites have tracked the gradual rise of the world's ocean in response to global warming. In August ...
New dating of sea-level records reveals rapid response between ice volume, polar temperature
A new study has revealed a rapid response between global temperature and ice volume/sea-level, which could lead to sea-levels rising by over one metre.
Warming temperatures will change Greenland's face
(Phys.org)—Global climate models abound. What is harder to pin down, however, is how a warmer global temperature might affect any specific region on Earth.
Enhanced melting of Northern Greenland in a warm climate
In a new study from the Bjerknes Centre for Climate Research, scientists show how the northern part of the Greenland ice sheet might be very vulnerable to a warming climate.
Scientists' role in swaying public opinion studied
(Phys.org)—Whatever their political persuasion, people are more likely to believe that global warming is caused by humans if they find out that most climate change scientists believe this is the case.
Why seas are rising ahead of predictions
Sea levels are rising faster than expected from global warming, and University of Colorado geologist Bill Hay has a good idea why. The last official IPCC report in 2007 projected a global sea level rise between ...
Scientists look at climate change, the superstorm
Climate scientist Michael Oppenheimer stood along the Hudson River and watched his research come to life as Hurricane Sandy blew through New York.
La Nina caused global sea level drop
The 2011 La Niña was so strong that it caused global mean sea level to drop by 5 millimeters (0.2 inches), a new study shows. Since the early 1990s, sea level has been rising by about 3 millimeters (0.1 inches) per year, ...
New understanding of Antarctic's weight-loss
(Phys.org)—New data which more accurately measures the rate of ice-melt could help us better understand how Antarctica is changing in the light of global warming.
Salt marsh carbon may play role in slowing climate warming
A warming climate and rising seas will enable salt marshes to more rapidly capture and remove carbon dioxide from the atmosphere, possibly playing a role in slowing the rate of climate change, according to a new study led ...
Sea level controls carbon accumulation in the Everglades
How much carbon is stored in the organic soils of tropical wetlands is becoming an important question as erosion, agriculture, and global climate change slowly set into motion a series of processes that could potentially ...
NASA's 'Earth Now' app now available for Android
(Phys.org)—One of the top iPhone education apps in the iTunes store is now available for Android. The free NASA "Earth Now" Android app immerses cyber explorers in dazzling visualizations of near-real-time ...
Weighing the Ocean: Solving the biggest problem in sea level science
(Phys.org)—Oceanographers from Newcastle and Liverpool have thought of a novel way to measure the ocean – weigh it.
Glacial thinning has sharply accelerated at major South American icefields
For the past four decades scientists have monitored the ebbs and flows of the icefields in the southernmost stretch of South America's vast Andes Mountains, detecting an overall loss of ice as the climate ...
