Not much has been said in media about those two methods (yesterday's post) that could mitigate global warming, sun screens and solar power generators in space. But if Chinese scientists do put the latter into effect soon, media will have to report it and we'll hear about it.
More methods are mentioned in Weathering Climate Change which might help prolong our climate stability.
Aerosols could be injected into the stratosphere to reduce global warming by 1.5 degrees C. Harvard University has such an experiment in its future plans. It could be somewhat cheaper, thus more doable, but there might be unintended consequences.
Carbon dioxide (CO2) could be filtered from the atmosphere and stored underground. The technology exists but is expensive.
Various agricultural changes have been suggested such as reform of rice paddy management and red meat alternatives. Ross doesn't mention Allan Savory's work, but I think it should be considered.
