Re: Unintended consequences
"Even if $GOVERNMENT, informed by the best scientific knowledge available, made a well intentioned effort at geo-engineering, I'm not convinced it would turn out well."
Even if a US Govt. did decide to launch a huge space mirror to cool down the USA, how is that really going to help the rest of the world? If it's not in a geostationary orbit, what happens if cooling affects other countries in bad ways? Do they get to shoot it down?
Any geoengineering project needs to be a world wide project, or at least have ALL the big players on board. And we all know just how long those negotiations will take.
