Fires Ravage the Amazon

Thousands of fires have broken out in the Amazon rainforest. Satellite data show that there are almost four times as many fires this year compared to the same period last year. Apart from Brazil, parts of Peru, Bolivia, Paraguay and Argentina have also been affected. While forest fires normally occur in Brazil’s dry season, which

Climate Report Shows Effects of Planet’s Warming Across Multitudes of Key Indicators

A new “State of the Climate” report released on Aug. 12, 2019, by the American Meteorological Society (AMS) confirms that 2018 was one of the hottest years on record. Global surface temperatures continued the trend in which every year since the turn of the 21st century has been hotter than any year experienced in the

NASA Targets Coastal Ecosystems with New Space Sensor

NASA selected a space-based instrument under its Earth Venture Instrument (EVI) portfolio that will make observations of coastal waters to help protect ecosystem sustainability, improve resource management and enhance economic activity. The selected Geosynchronous Littoral Imaging and Monitoring Radiometer (GLIMR) instrument, led by principal investigator Joseph Salisbury at the University of New Hampshire, Durham, will

Loss of Arctic’s Reflective Sea Ice Will Advance Global Warming by 25 Years

Losing the remaining Arctic sea ice and its ability to reflect incoming solar energy back to space would be equivalent to adding one trillion tons of CO2 to the atmosphere, on top of the 2.4 trillion tons emitted since the Industrial Age, according to current and former researchers from Scripps Institution of Oceanography at the

Flowing Antarctic Ice Mapped 10 Times More Accurately

Far more accurate than any previous map, this new representation of glacier flows in Antarctica opens the door to an improved understanding of the vast continent and the future pace of sea-level rise. To create the new map, researchers at the University of California, Irvine, and NASA’s Jet Propulsion Laboratory in Pasadena, Calif., combined input

It’s Official: Louisiana is Sinking

Louisiana is officially sinking. It has been 29 years since the National Geodetic Survey (NGS) measured the state’s subsidence. After completing four absolute gravity observations this past year, with the help of LSU’s Center for GeoInformatics (C4G), the NGS’s most-recent findings show the state’s change in elevation. “This is the second observation NGS has performed

Satellites Find Biggest Seaweed Bloom in the World

An unprecedented belt of brown algae stretches from West Africa to the Gulf of Mexico—and it’s likely here to stay. Scientists at the University of South Florida in St. Petersburg’s College of Marine Science used NASA satellite observations to discover and document the largest bloom of macroalgae in the world, dubbed the Great Atlantic Sargassum

Looking For Freshwater In All the Snowy Places

Snowflakes that cover mountains or linger under tree canopies are a vital freshwater resource for over a billion people around the world. To help determine how much freshwater is stored in snow, a team of NASA-funded researchers is creating a computer-based tool that simulates the best way to detect snow and measure its water content

Drones Paired with Thermal Cameras Spot Moisture under Roof Membranes

By John Anderson, Strategic Business Development, FLIR Systems Inc. A new tool is making roof inspections safer, faster, and more efficient by reducing the need for dangerous treks up and across rooftops. Many roof inspectors are now investing in unmanned aerial vehicles (UAVs)—commonly known as drones—equipped with thermal and visible cameras so they can more
