""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."

"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."

"“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.”"

"Climate engineering through cirrus cloud thinning, in contrast, mainly targets the long-wave radiation that is emitted from Earth."
