Newsweek: Climate Change and Geoengineering: Artificially Cooling Planet Earth by Thinning Cirrus Clouds

"Over recent decades, scientists from across the globe have been discussing the potential of geoengineering—the deliberate manipulation of the environment that could, in theory, cool the planet and help stabilize the climate."

Live Science: Cool the Planet? Geoengineering Is Easier Said Than Done

""If cirrus clouds behave like a blanket around the Earth, you're trying to get rid of that blanket," Lohmann, a professor of experimental atmospheric physics at ETH Zurich, told Live Science."

FCEA Blog: Carbon geoengineers: the debt collectors of the future

"Indeed, a recent report showed how none of the world’s top industries would be profitable if they paid for the true cost of natural capital. Granted, there has been some progress in the global decarbonization effort, but to date this has occurred on the fringes and in the absence of any enforceable targets to limit the total amount of atmospheric CO2."

Backdraft: Simon Nicholson on Climate Engineering

"“Although negotiators didn’t intend for this to be the case, now we’re kind of locked into a conversation where climate engineering is on the table,” says Nicholson. “If these [technologies] do start to come onto the table, then they can’t be used as cover for inaction. And that is perhaps the biggest political challenge in this space.”"

Business Insider: A last-resort ‘planet-hacking’ plan could make Earth habitable for longer — but scientists warn it could have dramatic consequences

"That idea, however, is extremely controversial. Some researchers believe such work could be a necessary part of the fight against climate change, but others argue that meddling with the planet exposes the world to a host of new risks. Plus, there's a growing fear that a rogue actor trying to achieve something "good" could attempt one of these globe-altering projects and spark a devastating international conflict."
