A team of researchers reports that sea level rise from greenhouse-induced warming of the Greenland ice sheet could be double or triple current estimates over the next century. (University of Wisconsin-Madison press release)

Scientists have exploited crystals from lavas to unravel the records of volcanic eruptions. (Durham University press release)

Greenhouse gas emissions from previously frozen organic carbon in soil are seen as larger than previously believed. (American Institute of Biological Sciences press release)

A fall in levels of atmospheric carbon dioxide, close to that of pre-industrial times, explains the transition from a mostly ice-free Greenland of three million years ago to the ice-covered region we see today. (University of Bristol press release)

Air circulates above the Earth in four distinct cells, with two each on either side of the equator, according to new research. (Imperial College London press release)

A study by a group of prominent seismologists suggests that a pattern of subtle but active faults makes the risk of earthquakes to the New York City area substantially greater than formerly believed. (The Earth Institute at Columbia University press release)

Researchers monitoring daily satellite images here of Greenland's glaciers have discovered break-ups at two of the largest glaciers in the last month. (Ohio State University press release)

Human-driven changes in the westerly winds are bringing hotter and drier springs to the American Southwest, according to new research. (University of Arizona press release)

Chemists have measured for the first time the impact that dirty smoke from ships cruising at sea and generating electricity in port can have on the air quality of coastal cities. (University of California - San Diego press release)

New research finds that coal burning, primarily in North America and Europe, contaminated the Arctic and potentially affected human health and ecosystems in and around Earth's polar regions. (National Science Foundation press release)

A new study shows that the number of "dead zones" – areas of seafloor with too little oxygen for most marine life – has increased by a third between 1995 and 2007. (Virginia Institute of Marine Science press release)

A new study provides the first observational evidence to confirm the link between a warmer climate and more powerful rainstorms. (University of Miami Rosenstiel School of Marine & Atmospheric Science press release)

Researchers have developed a new technique to precisely determine optical properties of brown carbon nanoparticles, with implications for more accurate prediction of climate change. (Arizona State University press release)

An unusual and amazing discovery of fossilized plants and insects in an ice-free region of Antarctica reveals the last traces of tundra before a dramatic and abrupt cooling some 14 million years ago. (Boston University press release)

Patagonia was thought to be subjected mainly to westerly winds off the Pacific, but a dual ice core analysis yielded the first evidence that this region also comes under the influence of meteorological regimes that arise further south, in the Antarctic. (Institut de Recherche Pour le Développement press release)

As the Arctic Ocean warms this century, shellfish, snails and other animals from the Pacific Ocean will resume an invasion of the northern Atlantic that was interrupted by cooling conditions three million years ago. (University of California - Davis press release)

Research suggests that extreme cooling that occurred within a short number of years 12,700 years ago was associated with a sudden change in the wind systems. (Helmholtz Association of German Research Centres press release)
