As usual, most commenters on this thread haven’t read this very thoughtful article. Note this essential quote from Dr. Bjorn:
“People are understandably nervous about geoengineering,” Lomborg acknowledged. “But many of the risks have been overstated. Marine cloud whitening, for example, amplifies a natural process and would not lead to permanent atmospheric changes – switching off the entire process would return the world to its previous state in a matter of days.”
What’s “thoughtful” about trying to come up with “solutions” to a nonexistent problem?
