Carbon emissions are chilling the atmosphere 90km above Antarctica, at the edge of space – The Conversation AU

While greenhouse gases are warming Earths surface, theyre also causing rapid cooling far above us, at the edge of space. In fact, the upper atmosphere about 90km above Antarctica is cooling at a rate ten times faster than the average warming at the planets surface.
Our new research has precisely measured this cooling rate, and revealed an important discovery: a new four-year temperature cycle in the polar atmosphere. The results, based on 24 years of continuous measurements by Australian scien…
