Members, I'm very disappointed that my robustly worded message regarding frequent and irrelevant cross posting from HPAC to the geo list has been widely ignored, including by many otherwise reputable people in this community. As a result I've had to take the entirely unprecedented step of

(source redacted for security reasons) Considering how Silver Lining likes to share how concerned they are with the governance of SRM https://twitter.com/SilverLiningNGO/status/1764788454037028916, this group might be interested to know that a new private meeting of the Silver Lining science

Oswald The group description now states solar geoengineering - but this hasn't been raised as an issue before, as I believe members are generally clear on the group's purpose. Methane (arctic or otherwise) is greenhouse gas removal, normally grouped with CDR. Just like cirrus cloud thinning is

It's an interesting discussion, as it actually raises questions about Iron Salt Aerosols more generally. My concern is they do too much - leading to uncertain magnitude and sign of effects. I'm happy to see ISA discussion on the geo list, if there's an obvious content cross over with SRM - re

The Geoengineering Google Group covers SRM only (including CCT, etc). This has been true since Greg Rau forked off the CDR Google group. I - and doubtless many other list members - are heartily sick of HPAC cross posting. I've asked politely already. If you continue to break the rules you will
