She finds it hard to get research and experiments funded because people find the topic "icky". But she explains, knowledge about what SRM would be doing and how, is not deep enough to assess it as a real option.
And she points out, once the real option looks like the lesser evil, it could already be too late – because the tipping point can be so close.
She splits the problem into two tipping points:
when convection in SubPolarGyre SPG South of Greenland grinds to a halt, and when the AMOC branch next to Europe collapses.
The SPG tipping is closer. And it might be an unavoidable chain reaction that, once SPG stopped, the right branch follows suit inevitably. Might. And might not.
If not, then injecting aerosols into the stratosphere could keep the European branch alive.
But at what cost, she asks. Teleconnections to for example the #Amazon do exist for both scenarios, cooling from SRM and a stopped AMOC.
Same goes for the Asian monsoon.
It's a half hour well spent to start forming an informed opinion about SRM.
