Although efforts to improve the fresh water side of the salmon's life cycle, many are not surviving their salt water stay. Global warming might be partially to blame.

Since 1983, sports fishermen from the Drammen River in Norway have been saving the scales of Atlantic salmon, caught as they return from years at sea to spawn in fresh water. A team of researchers including Jennifer McCarthy of the University of Massachusetts Amherst is using these scales to solve the mystery of why most of these endangered fish never survive their ocean stay.

Killing 83 acres of aspen and birch for environmental purposes might seem to be counter productive. However, scientists are hoping to learn that what comes after the kill will be more efficient at helping reduce greenhouse gases in the atmosphere.

Armed with chainsaws and pry bars, University of Michigan researchers and their colleagues recently hastened the end for nearly 7,000 mature aspen and birch trees in a large-scale, long-term experiment to glimpse the Great Lakes region's future forests.

The International Institute for Species Exploration at Arizona State University and an international committee of taxonomists – scientists responsible for species exploration and classification – has announced the top 10 new species described in 2007 and an SOS – State of Observed Species report card on human knowledge of Earth’s species.

The Royal Empress Tree has been dubbed the "wonder tree," providing numerous ecological and environmental benefits. The most recent discovery about this amazing tree is its ability to combat global warming through soil and air purification.

Recent agricultural discoveries have shed new light on how the average homeowner can do their part to combat global warming. Everyone knows the environmental benefit of planting trees, but not everyone knows the best trees to plant. The Royal Empress (Paulownia) Tree was once a godsend for barren lands suffering from erosion, but it also purifies the soil and cleans the air of pollutants and harmful gases more efficiently than any other tree available.

Clarkson University’s interdisciplinary engineering and management program is breaking new ground by preparing tomorrow’s business and technical leaders to incorporate environmental considerations into decision-making.

Launched more than 50 years ago, Clarkson University’s interdisciplinary engineering and management (iE&M) program has served as a model for subsequent programs developed by other universities.

Countries should avoid planting crops for biofuels that stand a high risk of becoming invasive species, according to a report released yesterday.

The Global Invasive Species Programme (GISP) has identified all the crops currently being used or considered for biofuel production and ranked them according to the risk they pose of becoming invasive species.

Some Oregon residents took some big steps to improve their environmental friendly living styles after completing a program at the University of Oregon. Their efforts resulted in reduced greenhouse emissions by two tons per person.

Forty-two Eugene-area residents took some big steps to improve their environmental friendly living styles after completing a newly developed Climate Master program at the University of Oregon. Their efforts resulted in reduced greenhouse emissions by two tons per person, according to a review of the program's first year.

Computer analyses of global climate have consistently overstated warming in Antarctica, new research concludes. The study can help scientists improve computer models and determine if Earth's southernmost continent will warm significantly this century, a major research question because of Antarctica's potential impact on global sea-level rise.

Computer analyses of global climate have consistently overstated warming in Antarctica, concludes new research by scientists at the National Center for Atmospheric Research (NCAR) and Ohio State University. The study can help scientists improve computer models and determine if Earth's southernmost continent will warm significantly this century, a major research question because of Antarctica's potential impact on global sea-level rise.

The Arctic has become a poster child for the negative effects of climate change, but new research from the University of Washington shows that species living in the tropics likely face the greatest peril in a warmer world.

Polar bears fighting for survival in the face of a rapid decline of polar ice have made the Arctic a poster child for the negative effects of climate change. But new research shows that species living in the tropics likely face the greatest peril in a warmer world.

Scientists confirm computer model predictions that oxygen-depleted zones in tropical oceans are expanding, possibly because of climate change.

An international team of physical oceanographers including a researcher from Scripps Institution of Oceanography at UC San Diego has discovered that oxygen-poor regions of tropical oceans are expanding as the oceans warm, limiting the areas in which predatory fishes and other marine organisms can live or enter in search of food.
