Is Earth on Fire?

Data from the Sentinel-3 World Fire Atlas shows that there were almost five times as many wildfires in August 2019 compared to August 2018, but a detailed analysis reveals precisely where these fires have been occurring, most of which were in Asia. The Copernicus Sentinel-3 mission recorded 79,000 fires in August this year, compared to

2019 Ozone Hole Is Smallest on Record

Abnormal weather patterns in the upper atmosphere over Antarctica dramatically limited ozone depletion in September and October, resulting in the smallest ozone hole observed since 1982, NASA and NOAA scientists reported. The annual ozone hole reached its peak extent of 6.3 million square miles (16. 4 million square kilometers) on Sept. 8, 2019, and then

NASA Smallsats Can Aid Hurricane Forecasts with GPS

Eight briefcase-size satellites flying in a row may be key to improving forecasts of a hurricane’s wind speed—detecting whether it will make landfall as a Category 1 or a Category 5. NASA’s Cyclone Global Navigation Satellite System (CYGNSS) fleet, launched in 2016, was designed to show whether the same GPS signals your phone uses for

Can Oceans Turn the Tide on Climate Crisis?

As we pump more greenhouse gases into the atmosphere, the world is warming at an alarming rate, with devastating consequences. While our vast oceans are helping to take the heat out of climate change, new research shows that they are absorbing a lot more atmospheric carbon dioxide than previously thought—but these positives may be outweighed

Mapping the Amazon

The Amazon basin is exceptional. It spans at least 6 million square kilometers (2.3 million square miles), nearly twice the size of India. It is home to Earth’s largest rainforest as well as the largest river for the volume of the flow and the size of the drainage basin. The rainforest, which covers about 80

2019 Arctic Sea Ice Minimum Is Second Lowest

Arctic sea ice reached its annual summer minimum on Sept. 18, 2019, according to NASA and the National Snow and Ice Data Center (NSIDC). Analysis of satellite data by NSIDC and NASA showed that the extent of ice cover this year effectively tied 2007 and 2016 as the second lowest in the satellite record, which

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
