Comment on Are We About To Be Assailed By Private Companies and Governments Implementing Geoengineering Experiments? by lenrosen4

In reply to Steve Papagiannis. In my science feed today another article appeared about iron seeding the ocean. For the life of me, I do not understand the tinkerers who look for shortcut solutions that once started will have to be done continuously when tackling the cause of ocean acidification and global warming is transparently obvious. I have read some of what David Keith has written in the past. I appreciate your impressions of the man.

Geoengineering at large scale will have so many unintended consequences. Our understanding of these dynamic systems is just too weak at this time to perform anything at scale. I do recall reading about David Keith ‘s thoughts years ago about geoengineering. At the time he thought it was an approach that should at least be studied in case we ever wanted to attempt it. I would rather direct our resources elsewhere because by the time we understood atmospheric engineering well enough, too much damage will occur.

As an aside, I studied physics in the same program at UofT with David Keith and even then I described him as frighteningly intelligent.
