The South Asian summer monsoon—critical to agriculture in Bangladesh, India, Nepal and Pakistan—could be weakened and delayed due to rising temperatures in the future, according to a recent climate modeling study. (Purdue University press release)

Globally, commercial ships emit almost half as much particulate pollution into the air as the total amount released by cars, according to a new study. (American Geophysical Union press release)

A team of scientists offers a new perspective on the nature of changing climatic conditions across this greenhouse-to-icehouse transition—one that refutes earlier theories and has important implications for predicting future climate changes. (Yale University press release)

New research suggests the hemlock woolly adelgid is killing hemlock trees faster than expected in the southern Appalachians and rapidly altering the carbon cycle of these forests. (USDA Forest Service press release)

2009-02-25 – Very large and abrupt changes in temperature recorded over Greenland and across the North Atlantic during the last Ice Age were actually global in extent, according to an international team of researchers. (Cardiff University press release)

Below the surface of Lake Huron, sinkholes harbor bizarre ecosystems where fish typical of the huge freshwater lake are rarely to be seen (American Geophysical Union press release)

Severe fires in Indonesia -- responsible for some of the worst air quality conditions worldwide -- are linked not only to drought, but also to changes in land use and population density, according to a new study. (University of Toronto press release)

An international group of scientists is renewing calls for policymakers to reduce both nitrogen and phosphorus when attempting to alleviate eutrophication -- or nutrient pollution problems—in fresh and coastal waters. (University of Maryland Center for Environmental Science press release)

Humidity expands global warming, according to a researcher who says that warming due to increases in greenhouse gases will lead to higher humidity in the atmosphere. And because water vapor itself is a greenhouse gas, this will cause additional warming. (Texas A&M University press release)

New research shows that the large-scale evolution of microbes was mostly complete 2.5 billion years ago, and that included the beginning of the modern aerobic nitrogen cycle. (University of Washington press release)

An international team of scientists have discovered that rainforest trees are getting bigger. They are storing more carbon from the atmosphere in their trunks, which has significantly reduced the rate of climate change. (University of Leeds press release)

Coastal erosion has more than doubled in Alaska -- up to 45 feet per year -- in a five-year period between 2002 and 2007 along a 40-mile stretch of the Beaufort Sea. (United States Geological Survey press release)

The Greenland and Antarctica ice sheets are melting, but the amounts that will melt and the time it will take are still unknown, researchers say. (Penn State press release)

Researchers have found that dengue transmission in Puerto Rico is dependent upon local climate and short-term changes in temperature and precipitation. (Public Library of Science press release)

Aerosols may have a greater impact on patterns of Australian rainfall and future climate change than previously thought, according to an atmospheric scientist. (CSIRO Australia press release)

A new study reveals that a part of the Strait of Juan de Fuca, which separates Washington state from Canada's British Columbia, is a potential "hot spot" for toxic harmful algal blooms affecting the Washington and British Columbia coasts. (NOAA Headquarters press release)
