Unforced variations: Nov 2021

This month’s open thread. The first two weeks will be dominated by COP-26, and various science updates that will be announced there, including this year’s Global Carbon Project report. Curiously, there is some archival interest in the climategate affair possibly in connection to COP-26 (a BBC dramatization “The Trick“, a BBC radio series on the security aspects “The Hack that Changed the World”, and a couple of months ago, a podcast episode of “Cheat!”). Please stick to science-related topics on this thread.
