Cloud control: geoengineering and nuclear war

Juicy quotes:

> The solution to global warming is to stop putting out greenhouse gas. And we know how to do that. We have the technology. It’s sun and wind

> If you could put a cloud in the stratosphere [...] it could cool the planet [... But] I don’t know of anybody who has come up with an idea of how to do it safely.

> The one thing called geoengineering that probably is a good idea is to take carbon dioxide out of the atmosphere. Unfortunately, it has the same name—geoengineering—as these other proposals

> I don’t really fear geoengineering because I don’t think it’s ever going to happen.

> The greatest fear [is] global nuclear war.

> the climate change caused by nuclear weapons could be much more devastating

> more people could die in China than in the United States and Russia combined, even if no bombs were dropped there

> the CIA called me up four years ago and asked, “Could we detect somebody else trying to control our climate?” Well yeah

> they were also asking is, “Can we control somebody else’s climate?”

> if you want to change the way people think you need a movie with Julia Roberts, not a professor giving a lecture.

> We worry about tipping points in the climate system but there are also tipping points in human behavior. If you look back at the United States 10 years ago, could you have imagined gay marriage or legalized pot or a black president?
