Vapourizing it, but yeah. I replied to the GP post with some brief discussion.

We're working in the lower troposphere (like 0-50 m). The stratosphere frightens me (and the folks who want to spray sulphur compounds up there are terrifying.

Water in the upper troposphere (AKA Marine Cloud Brightening) like Silver Lining is trying to do feels like a pretty good cooling approach. I wrote a jokey paper in the 80s about giant volcano-powered teakettles spewing steam into the upper atmosphere but the much simpler approach of simply spraying seawater into the air is clever.

Indeed, using existing ships as platform to vaporize salty water on the low atmosphere in the open ocean (I got it correctly?) is very clever.

Congratulations on the project.
