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

New Cheap Method of Surveying Landscapes Can Capture Environmental Change

Cheap cameras on drones can be used to measure environmental change which affects billions of people around the world, new research from the University of Exeter shows. Experts have developed a new way of surveying vegetation which greatly advances the tools available to ecologists and land managers seeking understand dryland ecosystems. Using standard ‘point and

Hundreds of Cities Commit to Combating Emissions

Washington, D.C.—Over 200 cities have set greenhouse gas reduction goals or targets. Action in these cities, which represent a combined population of 439 million people, could propel countries to meet their Intended Nationally Determined Contributions (INDCs)—–the national greenhouse gas reduction pledges embodied in the Paris Agreement. According to Can a City Be Sustainable?, the latest
