Before its September 2018 launch, the ICESat-2 mission team was focused on making sure the satellite met its science requirements, said Tom Neumann, the mission’s project scientist at NASA’s Goddard Space Flight Center in Greenbelt, Maryland. And it has, by precisely measuring the height of the ice sheets at Earth’s poles, of sea ice floes above the ocean waters, and of forest canopies.
The satellite’s continuous coverage around the globe, with height measurements of Earth’s surface taken every 2.3 feet (70 centimeters) along its ground path, has made ICESat-2 datasets appealing to those studying rivers, coastal regions, forests and more, he said.

COVID-19 has changed the way we live and work, as various health and safety restrictions keep more of us at home more often.
The resulting changes to our behavior are already impacting the environment around us in myriad ways, according to comparisons of remote sensing data before and during the pandemic collected by NASA, U.S. Geological Survey (USGS), and ESA (European Space Agency) Earth-observing satellites and others.

Lower-income residents and people of color are more likely to live in the hottest neighborhoods in cities across the country, putting them at greater risk of heat-related illnesses and death.
A trio of studies presented yesterday at the American Geophysical Union’s annual fall meeting underscored that sobering point.
“Disparities in urban heat exposure as a direct result of urban planning and design, environmental racism, and the policies such as redlining . do in fact exist,” said Angel Hsu, an environmental policy expert at the University of North Carolina, Chapel Hill, and lead author of one of the studies.
