   Very interesting article from the NYTimes about scientists on the front lines of monitoring the stratosphere to detect if someone starts geoengineering.

     Worryingly, some rogue actor might start geoengineering without any kind of global agreement. See, e.g., the book Termination Shock for a surprisingly plausible scenario. Or the bozos at Make Sunsets.

     That would be a supremely dangerous thing to do.

     This article also identifies one of the most important stratospheric issues. Over the last few years, my estimate of the odds that we'll engage in solar radiation management has gone from "no way" to "yeah, I can really see this happening".

     The last few years have proven me wrong. Probably the most amazing was the eruption of Hunga Tonga, but there were also fires dumping combustion products deep into the stratosphere, and some extreme ozone hole events.

     Many of these people are former colleagues from when I worked on the stratosphere. About 10 years ago, I thought that the stratosphere was done — all of the interesting questions had been answered.

     But nature has conspired to prove me wrong.
