Plant respiration could become a bigger feedback on climate than expected
New research suggests that plant respiration is a larger source of carbon emissions than previously thought, and warns that as the world warms, this may reduce the ability of Earth's land surface to absorb emissions due to fossil fuel burning.
A popular tool to trace Earth's oxygen history can give false positives
If someone cries 'Eureka!' because it looks like oxygen appeared in Earth's ancient atmosphere long before the body of evidence indicated, be careful. If it was a chromium isotope system reading that caused the enthusiasm, it might need to be curbed.
Transforming greenhouse gases: New 'supercatalyst' to recycle carbon dioxide and methane
Engineers have developed a new and cost-effective catalyst to recycle two of the main causes behind climate change -- carbon dioxide (CO2) and methane (CH4).
Climate change impacts already locked in, but the worst can still be avoided
Some impacts of global warming -- such as sea level rise and coastal flooding -- are already locked in and unavoidable, according to a major research project.
Shape of Lake Ontario generates white-out blizzards, study shows
A 6-foot-wide snow blower mounted on a tractor makes a lot of sense when you live on the Tug Hill Plateau. Tug Hill, in upstate New York, is one of the snowiest places in the Eastern US and experiences some of the most intense snowstorms in the world. This largely rural region, just east of Lake Ontario, gets an average of 20 feet of snow a year, and a new report explains why.
Study urges global-change researchers to embrace variability
A new review article presents evidence that argues for a more nuanced approach to the design of global-change experiments -- one that acknowledges and purposefully incorporates the variability inherent in nature.
Pacific Island countries could lose 50 -- 80% of fish in local waters under climate change
Many Pacific Island nations will lose 50 to 80 percent of marine species in their waters by the end of the 21st century if climate change continues unchecked, finds a new study. This area of the ocean is projected to be the most severely impacted by aspects of climate change.
How a tiny sea animal feeds itself, and the ocean
Dime-sized ocean organisms thought to graze on any particles in their path are actually picky eaters, and their food-filtering process may be vital to how organic materials are distributed from surface waters to the ocean floor, report investigators.
Off track: How storms will veer in a warmer world
The dry, semi-arid regions are expanding into higher latitudes, and temperate, rainy regions are migrating poleward. In a new paper, researchers provide new insight into this phenomenon by discovering that mid-latitude storms are steered further toward the poles in a warmer climate.
Amazon's recovery from forest losses limited by climate change
Deforested areas of the Amazon Basin have a limited ability to grow new trees because of changes in climate, according to a study.
