Re: [geo] SATAN

Of course it is perverse that our societies have failed to act against releases of GHGs but that is not a persuasive argument for those who believe there should be some form of advance review of outdoor SRM experiments. Like it or not, the need for social license for such experiments appears

Re: [geo] Make Sunsets: Clarifications!

Your web site claim that 1 gram of SO2 injected offsets the effect of 1 ton CO2 for a year is fundamentally misleading. Any effect on temperature of injected particles lasts only as long as the particles are in the stratosphere. If a one-time injection has a lifetime of 1-2 years that

And, we are not stopping emissions yet. Even under the most ambitious scenario (the LED scenario by Grübler, et al), cumulative additional CO2 emissions to 2100 from fossil energy use are over 630 Gt. Coupled with about 250 Gt of enhanced “nature-based” removals, the result is more than a
