Caltech’s Seismic Innovation Uses Undersea Earthquakes to Shake Up Climate Science
Despite climate change being most obvious to people as unseasonably warm winter days or melting glaciers, as much as 95 percent of the extra heat…

The Pantanal, a vast floodplain in South America, is among the largest wetlands in the world. The mosaic of grasslands, shrublands, forests, marshes, and lakes…
The Copernicus Sentinel-2 mission takes us over the Vatnajökull ice cap, in southeast Iceland, in this summery image captured on July 6, 2019. Covering an…
As large fires on the U.S. West Coast lofted vast plumes of smoke high into the atmosphere in September 2020, satellites and models tracked the…
NASA satellites provided a look at the rainfall potential in Hurricane Sally before and after it made landfall in southern Alabama. NASA’s Aqua satellite and…
An international effort that brought together more than 60 ice, ocean, and atmosphere scientists from three dozen international institutions has generated new estimates of how…
Ice-sheet models are an essential tool in making predictions regarding the future of the Greenland and Antarctic Ice Sheets. Nevertheless, these models still have a…
While the agency’s satellites image the wildfires from space, scientists are flying over burn areas, using smoke-penetrating technology to better understand the damage. A NASA…
It’s not often a new mass extinction is identified; after all, such events were so devastating they really stand out in the fossil record. In…
This series of four Copernicus Sentinel-2 images captured between June 29 and July 24, 2020, shows a segment of the largest ice shelf in the…
NASA’s Aqua satellite analyzed the cloud top temperatures and water vapor content in Hurricane Sally as it crawls toward landfall, and found the potential for…
The observations from Earth orbit show high-altitude concentrations of the gas that are more than 10 times typical amounts. NASA’s Atmospheric Infrared Sounder (AIRS), aboard…
Methane may not be as abundant in the atmosphere as carbon dioxide, but with a global warming potential many times greater than carbon dioxide, monitoring…
The closest analog to modern times is no longer very close, study finds. A new study of an ancient period that is considered the closest…
For the first time, long-term photogrammetic series document the “life cycle” of a volcano. The analyses shows that volcanoes have a kind of memory. Volcanoes…
The ocean takes up an estimated five to 12 gigatons of carbon dioxide per year through a process known as the biological carbon pump. More…
Climate and fire scientists have long anticipated that fires in the U.S. West would grow larger, more intense, and more dangerous. But even the most…
Wildfires continue to rage in the western United States. On September 9, 2020, the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra satellite captured this…
