A Third Of Global Sea Rise Caused By Melting Glaciers
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...

Dartmouth study contradicts predictions of widespread extinction A new Dartmouth College study finds human-caused climate change may have little impact on many species of tropical lizards, contradicting a host of recent studies that predict their widespread extinction in a rapidly warming planet. The findings, which appear in the journal Global Change Biology, offer new hope for survival of a creature thought to be doomed. Most predictions that tropical cold-blooded animals,...
WASHINGTON, May 16, 2013 /PRNewswire-USNewswire/ -- A new study of glaciers worldwide using observations from two NASA satellites has helped resolve differences in estimates of how fast glaciers are disappearing and contributing to sea level rise. (Logo: http://photos.prnewswire.com/prnh/20081007/38461LOGO) The new research found glaciers outside of the Greenland and Antarctic ice sheets, repositories of 1 percent of all land ice, lost an average of 571 trillion pounds (259...
April Flowers for redOrbit.com - Your Universe Online Climate change impacts on the surface of the Greenland Ice Sheet have been widely studied. An understanding, however, of the key processes in iceberg production has eluded researchers for a long time. A new study, led by the Universite Libre de Bruxelles, presents a sophisticated computer model that provides fresh insight into the impact of climate change on the production of icebergs by Greenland glaciers. The model also demonstrates...
C40 Risk Assessment Framework will help cities prioritize investment in climate actions NEW YORK, May 6, 2013 /PRNewswire-USNewswire/ -- The C40 Cities Climate Leadership Group (C40) today announced a new Clinton Global Initiative (CGI) Commitment to Action that will help cities better prepare for natural disasters and severe weather incidents. The new C40 Risk Assessment Framework will create a common approach for cities to assess climate risk and provide a process to help cities...
April Flowers for redOrbit.com - Your Universe Online Global warming may increase the risk for extreme rainfall and drought, a new NASA-led modeling study predicts. The study, to be published in the journal Geophysical Research Letters, demonstrates for the first time how rising carbon dioxide concentrations could affect the entire range of rainfall types on Earth. The research team analyzed computer simulations from 14 climate models that indicated wet regions of the world, such as the...
WASHINGTON, May 1, 2013 /PRNewswire-USNewswire/ -- NASA's newest scientific rover is set for testing May 3 through June 8 in the highest part of Greenland. (Logo: http://photos.prnewswire.com/prnh/20081007/38461LOGO) The robot known as GROVER, which stands for both Greenland Rover and Goddard Remotely Operated Vehicle for Exploration and Research, will roam the frigid landscape collecting measurements to help scientists better understand changes in the massive ice sheet. This...
In 2009, the North Carolina Coastal Resources Commission (CRC), a body that controls and regulates coastal development in North Carolina, asked 13 members of its advisory Science Panel to prepare a report on the state of sea-level rise in North Carolina. After the report was published, there was a subsequent maelstrom regarding its utility and validity. In this month's issue of EARTH Magazine, Orrin Pilkey and Alexander Glass from Duke University describe what happened. Based on the...
University of Hawaii - SOEST Projections of rainfall changes from global warming have been very uncertain because scientists could not determine how two different mechanisms will impact rainfall. The two mechanisms turn out to complement each other and together shape the spatial distribution of seasonal rainfall in the tropics, according to the study of a group of Chinese and Hawaii scientists that is published in the April 14, 2013, online issue of Nature Geoscience. The one mechanism,...
[ Watch the Video: Ocean Babies on Acid - The Time Machine ] Lee Rannals for redOrbit.com - Your Universe Online Scientists have uncovered some surprising abilities in sea urchins living along the coast of California and Oregon. A group from Stanford discovered that some purple sea urchins have the ability to rapidly evolve in acidic ocean water, which is a skill that could come in handy as climate change increases. This ability allows urchins to have healthy growth in water with...
April Flowers for redOrbit.com - Your Universe Online Global sea levels would rise by 24 feet if the sheet of ice covering Greenland were to melt in its entirety tomorrow. But it is very unlikely that nearly two million cubic miles of ice will wash into the ocean overnight. Researchers have been tracking increasing melt rates since 1979. Last summer the melt was so extensive that ice core records show similar events only about once every 150 years over the last four millennia. "In...

Climate change is a substantial and lasting change in the statistical distribution of weather patterns over periods of time ranging from decades to millions of years. It might be a change in the average weather conditions, or in the distribution of weather around the average conditions. Climate change is a result of factors that include oceanic processes, biotic processes, variations in solar radiation received buy Earth, volcanic eruptions, and plate tectonics, and human induced alterations...
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...
If you live Honolulu Hawaii or the surrounding low elevation area’s this is what you can roughly expect to see with impacts of the three features below when it comes to your heating and cooling budget. The above graph shows the situations that occurred during previous phases of all three events such as normal conditions along with EL-Nino and La-Nina. During a normal cycle it is easy to see that the cooling degree days during March were around 355.5 days. During the same month of March...
El-Nino is marked with having warmer waters in the Pacific Ocean, so how can it have impacts on Austin Texas. This is a look at what occurred during an EL-Nino event as we evaluate three months of the cycle. January 2012- March 2012 La-Nina Impacts on Austin TX Climate January 2012 Normal temperatures for the month are usually around 40-60F. Examining what occurred during the month of January during an EL-Nino event the temps where average 40% of the month. While, 21% of the month...
