Clumped 18O –18O in Ice Reveals Past Ozone and Wildfire
Reactive gases like ozone are hard to preserve, but clumped isotopes and models provide clues to past ozone and suggest a global increase in wildfire at megafaunal extinction.
Linking African Winds to Atlantic Storms
Simulations suggest that waves in the atmosphere above northern Africa influence the intensity, timing, and location of formation of Atlantic tropical cyclones.
If There Is Phosphine on Venus, There Isn’t Much
New observations of the Venusian atmosphere collected from an airborne observatory showed no sign of the potential biosignature gas, casting additional doubt on a previous report of its detection.
