An Air Parcel’s Journey Through the Stratosphere

by Hella Garny 25 April 202525 April 2025

The “age of stratospheric air” measures the speed of the global transport circulation in the stratosphere, which is crucial for understanding the distribution of important trace gases, like ozone.

Uncertainty Abounds in Seeding the Sky to Fight Climate Change

Sarah Derouin, Science Writer by Sarah Derouin 9 January 20249 January 2024

Some scientists have suggested injecting solid particles such as alumina, calcite, or even diamonds into the atmosphere to temporarily limit climate warming. But new research shows there are still big unknowns.
