New research supports the hypothesis that dinosaurs were done in by climate change after an asteroid impact kicked up a massive plume of sulfur gases that circled the globe for several decades.
Sediment cores from northwestern China reveal freezing conditions during the Late Triassic killed off many forms of life—but not dinosaurs.
Networks of valleys provide puzzling hints of running water on the surface of the Red Planet. New research suggests that some tributaries could have formed from icy sheets thousands of meters thick.
An upward trend in fossilized charcoal indicates that wildfires may have contributed to extinctions during the Great Dying.
During a brief period in Earth’s past, a massive emission of carbon abruptly raised global temperatures, acidified oceans, and stamped out species. New data may help explain how it happened.
A new method shows a key relationship between the width and makeup of Earth’s river channels over time. The technique could be applied to other terrestrial bodies, such as Mars.
Antarctica’s Thwaites and Pine Island Glaciers are melting faster than they have in the past 5,500 years, new evidence shows. Against expectations, their pasts have been remarkably stable.
As a young Latina, Pérez-Ángel brings a fresh perspective to paleoclimatology.
Community science builds bridges while generating valuable environmental data.
By studying bits of rock scooped up by ancient glaciers, researchers have pinned down that recent glacial variability was driven, in part, by changes in the direction of Earth’s axis of rotation.
