Dr. Lyndsey McMillon-Brown was hoping to see anything but mustard yellow. When the NASA research electrical engineer clicked open the photo of a small sample — a swatch of film no bigger than a sticky note — she let out a cheer. The film was still dark black after spending … [continued]
20 years ago, when meteorologist John Haynes first went to Washington, DC, there was so much pollution that he could stand on the roof of NASA headquarters and see airborne residues of the neighboring interstate highway. He claims that a cloud of smog extended all the way into Virginia and … [continued]
A pilot project has estimated emissions and removals of carbon dioxide in individual nations using satellite measurements.
Kids are sponges when it comes to learning about renewable energy, and hands-on, experiential activities are fun ways to make zero emissions living tangible.

Cyclone Gabrielle has been lashing New Zealand with strong winds and heavy rain in mid-February 2023, adding to what has already been an unusually wet start to the year. The latest round of extreme weather brought destructive flooding, storm surge, and landslides to the region. The Visible Infrared Imaging Radiometer … [continued]
Aviation is a big deal for climate change. Not only is it a big contributor, but it’s an area where changes to improve efficiency can have a huge impact. For this reason, both private companies and government agencies know this is a great target to both save money and protect … [continued]
2022 effectively tied for Earth’s 5th warmest year since 1880, and the last 9 consecutive years have been the warmest 9 on record. NASA looks back at how heat was expressed in different ways around the world in 2022. Credit: NASA’s Goddard Space Flight Center/Kathleen Gaeta Editor’s Note: This release was … [continued]
Thinning of the Northeast Greenland Ice Stream
Greenland’s largest ice stream is expected to contribute more to sea level rise than models previously indicated.

Greenland is home to the planet’s largest ice sheet outside of Antarctica. Observations collected from the ground, air, and space have revealed rapid thinning in the northeast part of this ice sheet that could contribute more to sea level rise than previously thought. “Rivers” of relatively fast-moving ice, known as … [continued]
