Hi—The reasons that aerosols (whether sulfur or some other substance) and cloud brightening are being considered is that they can work quickly. Bringing down the CO2 is fine, but takes far, far too long. Present global emissions total something like 10 GtC/yr (multiply by 3670 to get to the MMTCO2

John- Couldn't you quickly create the desired effect of MCB by injecting salt particles using aircraft?? If the formation of salt particles could be done on a large enough scale on land, it seems that aircraft could release them very strategically to create maximum benefit. This might be more

Dear Steve, In the article about your parliamentary hearing, it says: Everybody working in geo-engineering hopes it won't be needed - but we fear it will be, said Prof Salter. This is incorrect, and I would like to request that you issue a statement to that effect. You are not speaking for

[geo] Calgary meeting on Direct Air Capture - thoughts?

List: 1. I thought this list had a very useful dialog a few months ago on the CDR technology called Direct Air Capture (DAC - sometimes Artificial Trees). I have just become aware of an invitation-only meeting on this topic - hosted by the group ISEEE at the University of Calgary on March 6
