An asteroid, also known as the Chicxulub Impactor, hit Earth some 66 million years ago, causing a crater 180 km wide. The impact of the asteroid heated organic matter in rocks and ejected it into the atmosphere, forming soot in the stratosphere. Soot is a strong, light-absorbing aerosol that caused global climate changes that triggered […]
WASHINGTON D.C. — The Chicxulub asteroid impact that wiped out the dinosaurs likely released far more climate-altering sulfur gas into the atmosphere than originally thought, according to new research. A new study makes a more refined estimate of how much sulfur and carbon dioxide gas were ejected into Earth’s atmosphere from vaporized rocks immediately after the […]

The monetary impact of changes in snowfall due to climate change is likely in the trillions of dollars. Professor Matthew Sturm, with the University of Alaska Fairbanks Geophysical Institute, reported in a recent paper for the American Geophysical Union that the costs of snowfall changes are “measured in trillions, not billions, of dollars.” Sturm collaborated […]
