So let me get this straight: in the face of a failure to control global warming by other means, you'd prefer your anxiety about possible risks to prevent any attempt to counter the warming by this approach, dooming the world to potentially catastrophic temperature increases?
Not really? We have no idea the relativity of our change vs what's supposed to happen when coming out of an ice age because of our short window we are observing.
We may change the climate in our entire history as much as a super volcano does, or many times less.
Are YOU serious?
