Climate Change is Affecting North American Fish

Climate change is already affecting inland fish across North America — including some fish that are popular with anglers. Scientists are seeing a variety of changes in how inland fish reproduce, grow, and where they can live, according to four new studies published this week in a special issue of Fisheries magazine. “Thanks to this synthesis,

Understanding Forest Fire History Can Help Keep Forests Healthy

COLUMBIA, Mo. – For nearly a century, forest fires have been viewed by scientists and the public as dangerous and environmentally damaging disasters. However, recent research has shown that forest fires are vital to maintaining healthy forests. While people in the western portions of the U.S. experience forest fires often and know of their value,

Researchers Demonstrate Effectiveness of Single Photon LiDAR for Forest Mapping

A team of scientists from the University of Maryland and Sigma Space Corporation has shown that 3D forest structure and topography can be measured rapidly, efficiently and accurately over large areas, using an innovative laser technology called single photon lidar (SPL).

Understanding Ice Loss in Earth’s Coldest Regions

How do ice sheets melt in places where surface conditions are too cold for melting? Glaciers in the McMurdo Dry Valley rarely are observed to be actively melting, yet runoff from these glaciers feeds streams, lakes, and associated ecosystems in the valleys, which are among the coldest and driest ecosystems on Earth. The processes generating

El Niño Could Drive Intense Season for Amazon Fires

Irvine, Calif., June 29, 2016 – The long-lasting effects of El Niño are projected to cause an intense fire season in the Amazon, according to the 2016 seasonal forecast from scientists at NASA and the University of California, Irvine. El Niño conditions in 2015 and early 2016 altered rainfall patterns around the world. In the

Climate Change Has Reshuffled UK Wildlife Calendar

Climate change is already affecting the UK’s wildlife calendar, and it’s likely this will continue into the future, according to new research published in the journal Nature. The results suggest that seasonal events – such as the timing of flowering in plants and bird breeding behaviour – are generally more sensitive to temperature change, than

Better Information is Needed to Understand Extreme Weather

Scientists need more credible and relevant information to help communities become more resilient. Researchers need improved techniques to be able to understand why the climate is changing, and the part humans play in this process, according to Professor Peter Stott, who leads the Climate Monitoring and Attribution team at the Met Office and is also

Carbon Dioxide Biggest Player in Thawing Permafrost

Carbon dioxide emissions from dry and oxygen-rich environments will likely strengthen the climate forcing impact of thawing permafrost on top of methane release from oxygen-poor wetlands in the Arctic, according to a study in Nature Climate Change led by Northern Arizona University assistant research professor Christina Schädel. Schädel’s meta-analysis of 25 Arctic soil incubation studies

Earth Scientists Push Boundaries of 3D Modeling

Robert Moucha, assistant professor of geophysics, and Gregory Ruetenik, a Ph.D. student in Earth sciences, have collaborated with Gregory Hoke, associate professor of Earth sciences, on a unique numerical modeling study that simulates changing terrain over millions of years. Their study shows that moderate changes in dynamic topography produce an erosional response in the form
