Satellite Data Record Shows Climate Change’s Impact on Fires

Hot and dry. These are the watchwords for large fires. While every fire needs a spark to ignite and fuel to burn, it’s the hot and dry conditions in the atmosphere that determine the likelihood of a fire starting, its intensity and the speed at which it spreads. Over the past several decades, as the

NASA’s ARIA Team Maps Flooding in Bahamas

The Advanced Rapid Imaging and Analysis (ARIA) team at NASA’s Jet Propulsion Laboratory in Pasadena, Calif., in collaboration with the Earth Observatory of Singapore (EOS), used synthetic aperture radar data from the European Union’s Copernicus Sentinel-1 satellites to produce this flood map of the Bahamas. The light-blue color indicates areas that were likely flooded when

Landsat Illustrates Five Decades of Change to Greenland Glaciers

Ice fronts have retreated, rocky peaks are more exposed, fewer icebergs drift to the ocean: the branching network of glaciers that empty into Greenland’s Sermilik Fjord has changed significantly in the last half century. Comparing Landsat images from 1972 and 2019, those changes and more come into view. The glaciers appear brownish grey in this

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
