Record warm summers cause extreme ice melt in Greenland
An international team of scientists, led by Dr Edward Hanna at the University of Sheffield, has demonstrated that recent warm summers have caused the most extreme Greenland ice melting in 50 years. The new research provides further evidence of a key impact of global warming and helps scientists place recent satellite observations of Greenland´s shrinking ice mass in a longer-term climatic context.

that the oceans have been absorbing heat since 1951 and will continue
to absorb more heat from the atmosphere over the next 50 years. This increasing

less than previous studies projected, while the ocean acts as a bigger

New Study by Scripps Researchers Shows Western Wildfires Are Linked to Variations in Climate — Scientists from the California Applications Program at Scripps Institution of Oceanography at the University of California, San Diego, have found a link between variations in climate and the severity of wildfires that spans a range of regions and ecosystems across the Western U.S. over the last two decades.
In developing the first comprehensive database of Western wildfires, the researchers found that, for particular vegetation types across the West, the acres burned tend to result from a few characteristic patterns in moisture surplus or deficit that develop over a few to several seasons. The type of vegetation is key because it determines the growth of wildfire fuel and how it stores moisture.
"The database provides evidence for a direct link between climate, vegetation, and wildfire severity," said Anthony Westerling, a Scripps researcher and lead author of the study appearing in the May issue of the Bulletin of the American Meteorological Society. Newsrelease: Word Version PDF Version
