A University of Rhode Island student finds evidence suggesting some songbirds may avoid eating insects that consume leaves exposed to high levels of carbon dioxide. (University of Rhode Island press release)

Scientists say icy clouds found at the edge of space are higher at the South Pole than at the North because of more intense solar radiation during the austral summer, helping researchers understand the role of these clouds as indicators of climate change. (British Antarctic Survey press release)

Scientists say they need to adjust various calculations concerning the ongoing effects of carbon dioxide because one component, graphitic black carbon, does not erode as quickly as previously believed. (University of Washington press release)

Earth and space scientists say that a recent paper attributing most climate change on Earth to cosmic rays is incorrect and that carbon dioxide emissions are the primary cause of global warming.

United States and Russian scientists say massive Siberian peat bogs, widely known as the permanently frozen home of untold kilometers of moss and uncountable hordes of mosquitoes, also are huge repositories for gases that are thought to play an important role in the Earth's climate balance.

A team of Penn State meteorologists finds corn earworm travel is predictable through use of weather forecasting models and analysis of wind data, allowing farmers to take appropriate action. (Penn State University press release)

Sediment samples dating back thousands of years and taken from under the deep water of West Olaf Lake in Minnesota have revealed an unexpected climate indicator that can be factored into future projections. (University of Illinois at Urbana-Champaign press release)

Researchers say key mutations in the mitochondrial DNA of human cells may have helped our migrating ancestors adapt to more northerly climates and ultimately link people with this ancestral history to specific diseases. (University of California-Irvine)

Harvard scientists say the air Americans breathe contains more ozone from pollution than EPA estimates, posing greater health risks. (American Geophysical Union release)

Climate change could drive more than a quarter of land animals and plants into extinction by 2050, according to a group of international scientists. (Conservation International press release)
