NY Times Essay by David Keith: "What’s the Least Bad Way to Cool the Planet?"

[JFDee]

David Keith intensifies his advocacy for SRM.

To cool the planet in this century, humans must either remove carbon from the air or use solar geoengineering, a temporary measure that may reduce peak temperatures, extreme storms and other climatic changes. Humans might make the planet Earth more reflective by adding tiny sulfuric acid droplets to the stratosphere from aircraft, whitening low-level clouds over the ocean by spraying sea salt into the air or by other interventions.

Yes, this is what it comes down to: carbon removal or solar geoengineering or both. At least one of them is required to cool the planet this century. There are no other options.

Moreover, the cost of this is much less than the cost of cooling the entire planet.
