What Causes Nitric Oxide to Infiltrate the Ozone Layer?
Processes in the polar atmosphere can cause nitric oxide (NO)-enriched air to descend and destroy stratospheric ozone. Scientists explore one cause of these NO fluxes, stratospheric sudden warming.

A Dearth of Hurricanes Cannot Explain Maya Collapse
Mud layers in a stalagmite from a cave on the Yucatán Peninsula show hurricane activity was steady or elevated throughout the Maya collapse.

Upper Atmosphere Has Cooled Steadily for Three Decades
Scientists projected that the upper atmosphere would continue to cool and contract with rising greenhouse gas emissions. Now, these projections have been confirmed for the first time.
