Rising carbon dioxide levels associated with global warming may affect interactions between plants and the insects that eat them, altering the course of plant evolution, research at the University of Michigan suggests.
As debate continues about potential policies to curb greenhouse gas emissions, new research shows the world is already committed to a warmer climate because of emissions that have occurred up to now.
A new analysis of sulfur emissions shows that after declining for a decade, worldwide emissions rose again in 2000 due largely to international shipping and a growing Chinese economy. An accurate read on sulfur emissions will help researchers predict future changes in climate and determine present day effects on the atmosphere, health and the environment.
New, high-resolution ocean circulation models suggest that massive glacial meltwaters assumed to have flooded the North Atlantic 8,200 years ago, drastically cooling Europe, instead flowed thousands of miles further south. Results dramatically affect our understanding of what causes climate change.
A team of researchers America identified the most important questions that future generations will face when dealing with changes in soil structure. These questions will serve as a guide for direction of soil science research.

Researchers will analyze satellite data, as well as historical climate and fire data, for the entire continent of Australia, the lower 48 states in North America, and the Amazon region in South America.
Researchers investigating how large dams can affect local climates say dams have the clear potential to drastically alter local rainfall in some regions. The study—published in Geophysical Research Letters— marks the first time researchers have documented large dams having a clear, strong influence on the climate around artificial reservoirs, an influence markedly different from the climate around natural lakes and wetlands.
The La Nina Pacific Ocean cooling event continues to pull down temperatures, with the global average temperature falling below seasonal norms for the first time in 18 months and only the second time in almost two and a half years.
Wolverine habitat in the northwestern United States is likely to warm dramatically if society continues to emit large amounts of greenhouse gases, according to new computer model simulations carried out at NCAR. The study found that climate change is likely to imperil the wolverine in two ways: reducing or eliminating the springtime snow cover that wolverines rely on to protect and shelter newborn kits, and increasing August temperatures well beyond what the species may be able to tolerate.
The year 2010 finished in a photo finish with 1998 for the warmest year in the 32-year satellite temperature record. 2010 was only 0.013 C cooler than 1998, an amount that is not statistically significant.
The magnitude of climate change during Earth’s deep past suggests that future temperatures may eventually rise far more than projected if society continues its pace of emitting greenhouse gases, a new analysis concludes. Building on recent research, the study examines the relationship between global temperatures and high levels of carbon dioxide in the atmosphere tens of millions of years ago.
New results from a Baylor University study show that different behaviors and strategies lead some families to cope better and emerge stronger after a weather-related event.
Alexander Graham Bell once said that when one door closes another one opens, and the open doors of the Woods Hole Oceanographic Institution (WHOI) Data Library and Archives are making it possible to help preserve the voluminous archives of GLOBEC, a study of Global Ocean Ecosystem Dynamics, which closed at the end of 2009.
The amount of dust in the Earth’s atmosphere doubled since the beginning of the 20th century and the dramatic increase is influencing climate and ecology around the world, according to a new study led by Natalie Mahowald, Cornell associate professor of earth and atmospheric sciences.
An international team of scientists has released data indicating that greenhouse gas uptake by continents is less than previously thought because of methane emissions from freshwater areas.
For Boston, 2010 was the hottest year since at least 1872, according to the Northeast Regional Climate Center at Cornell University. Four other cities in New England also had their all-time hottest year. In all, 23 of the 35 cities monitored saw the average temperature for 2010 rank among the 10 hottest years on record.
A new study finds that microscopic particles of dust, emitted into the atmosphere when dirt breaks apart, follow similar fragment patterns as broken glass and other brittle objects. The research suggests there are several times more dust particles in the atmosphere than previously believed, since shattered dirt appears to produce an unexpectedly high number of large dust fragments. The finding has implications for understanding future climate change because dust plays a significant role in controlling the amount of solar energy in the atmosphere.
A new study of sea-level trends by researchers at the Virginia Institute of Marine Science brings both good and bad news to localities concerned with coastal inundation and flooding along the shores of Chesapeake Bay.
November 2010 came in as the third warmest November in the 32-year satellite temperature record, but still warmer than November 1998. From January through November, that leaves 2010 only 0.012 C (0.022° F) cooler than 1998, which was the warmest year in the satellite record.
A Kansas State University professor is part of a national research team that discovered that streams and rivers produce three times more greenhouse gas emissions than estimated by the Intergovernmental Panel on Climate Change.

Two Michigan environmental scientists advocate for scientist-advocacy on issues of environmental ethics.
When it comes to controlling carbon emissions, a Case Western Reserve University political scientist challenges conventional views that countries are the only rule makers in international politics of climate change. Jessica Green from the College of Arts and Sciences reports that today’s gold standard for measuring the carbon footprint of firms and organizations was created by the collaborative efforts of NGOs and the private sector—not by countries forging the Kyoto Protocol.
The Earth is constantly manufacturing new crust, spewing molten magma up along undersea ridges at the boundaries of tectonic plates. Now, scientists at the Woods Hole Oceanographic Institution (WHOI) have observed ocean crust forming in an entirely unexpected way—one that may influence those cycles of life and carbon and, in turn, affect the much-discussed future of the world’s climate.

As the ice-capped Arctic Ocean warms, ship traffic will increase at the top of the world. And if the sea ice continues to decline, a new route connecting international trading partners may emerge -- but not without significant repercussions to climate, according to a U.S. and Canadian research team that includes a University of Delaware scientist.
The United States and many other heavily populated countries face a growing threat of severe and prolonged drought. The analysis concludes that warming temperatures associated with climate change will likely create increasingly dry conditions across much of the globe in the next 30 years, possibly reaching a scale in some regions by the end of the century that has rarely, if ever, been observed in modern times.
A University of Washington conservation biologist is behind the effort to build nests in the barren rocks of the Galápagos Islands in the hope of increasing the population of an endangered penguin species.
While it’s still hotly debated among scientists whether climate change causes a shift from the traditional form of El Nino to one known as El Nino Modoki, online in the journal Nature Geoscience, scientists now say that El Nino Modoki affects long-term changes in currents in the North Pacific Ocean.
Climate change in the Prairie Pothole Region poses problems for wetland-dependent organisms such as ducks, but farmers could help ease the impact by the way they farm.
