[geo] Climate Book review

RE: [geo] Climate Book review
us on albedo. Stopping climate change requires stopping tipping points, which requires higher albedo. While it is true in the long term that we should bring the GHG level back to the Holocene norm, that is a slow task. 6. governance of an SAI programme… ideally would have the consent of all the people on the planet. This is from the author not the reviewer. Green movements have a quasi-religious opposition to Stratospheric Aerosol Injection, based on their historic origins in thinking that is closely related to the communist movements which saw class struggle as a fight between good and evil. Their political war against fossil fuels is a form of class struggle that has morphed in green ideology from a means to stabilise the climate into an end in itself. Converting greens to understand the climate science of direct cooling may well be more difficult than converting denialists. Decisions to cool the planet will likely require implementation without the consent of ideological opponents. Smith is correct this will be a massive challenge, but it is a profound and tragic irony that the people who profess to care the most about climate change are now doing the most to prevent effective investment to reverse it. This is a moral problem that requires much more public conversation to expose the hypocrisy and inconsistency of opponents of geoengineering.
