This is a comment about Crutzen's ideas about geoengineering.

The idea of putting sulphur in the upper atmosphere is mainly not taken seriously because of C's track record, but because some volcanos do it, and it has measurable effects on global temperature. This is no speculation, see the article on Mount Pinatubo. — Preceding unsigned comment added by 2003:D5:3F19:6933:EDB4:DBE4:44B1:7E2D (talk) 21:00, 10 January 2020 (UTC)[reply]
