Researchers establish common seasonal pattern among bacterial communities in Arctic rivers
New research on bacterial communities throughout six large Arctic river ecosystems reveals predictable temporal patterns, suggesting that scientists could use these communities as markers for monitoring climate change in the polar regions. view more (2009-11-24)
Aquatic creatures mix ocean water
Understanding mixing in the ocean is of fundamental importance to modeling climate change or predicting the effects of an El Niño on our weather. Modern ocean models primarily incorporate the effects of winds and tides. However, they do not generally take into account the mixing generated by swimming animals. view more (2009-11-23)
Research challenges for understanding landscape changes identified
Nine research challenges and four research initiatives that are poised to advance the study of how Earth's landscapes change were unveiled today in a new report by the National Research Council. view more (2009-11-19)
Experts: Failure to focus on farming will undermine global climate agreement and increase hunger
Alarmed by a substantial oversight in the global climate talks leading up to the United Nations Climate Change Conference in Copenhagen next month, more than 60 of the world's most prominent agricultural scientists and leaders underscored how the almost total absence of agriculture in the agreement could lead to widespread famine and food... view more...

Climate variability and dengue incidence
Research published this week in PLoS Medicine demonstrates associations between local rainfall and temperature and cases of dengue fever, which affects an estimated fifty million people per year worldwide. view more (2009-11-16)
New Water Management Tool May Help Ease Effects of Drought
Continued improvement of climate forecasts is resulting in better information about what rainfall and streamflow may look like months in advance. view more (2009-11-13)
Record highs far outpace record lows across US
Spurred by a warming climate, daily record high temperatures occurred twice as often as record lows over the last decade across the continental United States, new research shows. view more (2009-11-13)
A Lightning Strike in Africa Helps Take the Pulse of the Sun
Sunspots, which rotate around the sun's surface, tell us a great deal about our own planet. Scientists rely on them, for instance, to measure the sun's rotation or to prepare long-range forecasts of the Earth's health. view more (2009-11-12)
Climate studies to benefit from 12 years of satellite aerosol data
Aerosols, very small particles suspended in the air, play an important role in the global climate balance and in regulating climate change. view more (2009-11-11)
Controversial new climate change results
New data show that the balance between the airborne and the absorbed fraction of carbon dioxide has stayed approximately constant since 1850, despite emissions of carbon dioxide having risen from about 2 billion tons a year in 1850 to 35 billion tons a year now. view more (2009-11-11)
Cave Study Links Climate Change to California Droughts
California experienced centuries-long droughts in the past 20,000 years that coincided with the thawing of ice caps in the Arctic. view more (2009-11-11)
Central Africa's tropical Congo Basin was arid, treeless in Late Jurassic
The Congo Basin - with its massive, lush tropical rain forest - was far different 150 million to 200 million years ago. At that time Africa and South America were part of the single continent Gondwana. view more (2009-11-11)
Reducing greenhouse gases may not be enough to slow climate change
Because land use changes are responsible for 50 percent of warming in the US, policymakers need to address the influence of global deforestation and urbanization on climate change, in addition to greenhouse gas emissions. view more (2009-11-11)
Antarctica glacier retreat creates new carbon dioxide store
Large blooms of tiny marine plants called phytoplankton are flourishing in areas of open water left exposed by the recent and rapid melting of ice shelves and glaciers around the Antarctic Peninsula. view more (2009-11-10)
Past climate of the northern Antarctic Peninsular informs global warming debate
The seriousness of current global warming is underlined by a reconstruction of climate at Maxwell Bay in the South Shetland Islands of the Antarctic Peninsula over approximately the last 14,000 years, which appears to show that the current warming and widespread loss of glacial ice are unprecedented. view more (2009-11-09)
Nitrogen loss threatens desert plant life, study shows
As the climate gets warmer, arid soils lose nitrogen as gas, reports a new Cornell study. That could lead to deserts with even less plant life than they sustain today, say the researchers. view more (2009-11-09)
Paleoecologists offer new insight into how climate change will affect organisms
An article in the Proceedings of the National Academy of Science written by a team of ecologists, including Robert Booth, assistant professor of earth and environmental science at Lehigh University, examines some of the potential problems with current prediction methods and calls for the use of a range of approaches when predicting the impact of... view more...

Study gives clearer picture of how land-use changes affect U.S. climate
Researchers say regional surface temperatures can be affected by land use, suggesting that local and regional strategies, such as creating green spaces and buffer zones in and around urban areas, could be a tool in addressing climate change. view more (2009-11-04)
Calm before the spawn: Climate change and coral spawning
What's the point of setting up marine reserves to protect coral reefs from pollution, ship groundings and overfishing if climate change could cause far more damage? A study published this week in London in Proceedings of the Royal Society B provides the answer. view more (2009-11-04)
