Well, yes, no-one would deploy any form of SRM based on today’s knowledge, that’s why we need more research. But I don’t get why people have to make this all into some competition. CDR and SRM are different. They don’t do the same thing to the climate. Words like “best” only make sense

Another thinly veiled fantasy about globally scaled nuclear power being the answer to all energy/climate problems. We have most of the clean energy technology that we need already and forever invoking a nuclear powered future is an attempt to deny what is happening in the real world. LDM p7

Im afraid that both of these replies illustrate the problems associated with SRM in the form of MCB.We simply dont know what the effect of the large scale (ie sufficient to have noticeable effect) implementation of any SRM technique will be and the public will not be impressed by these

Hi Andrew, thank you. No, you did not misunderstand our paper. If by particle rain-out you are referring to sulfate particles settling from the stratosphere to the upper troposphere and thus affecting freezing by increasing the number of available IN for homogeneous freezing, what we found, in

Poster's note: this is very important paper, as it constrains a key side-effect of SAI. I may misunderstand the paper, but I don't think it's looking at particle rain-out - which may provide a further mechanism Upper tropospheric ice sensitivity to sulfate geoengineering Daniele Visioni1,2,

[geo] Methane Efficacy

Dear All, Here is the link to our recent paper on the efficacy of Methane in Climate Dynamics. https://link.springer.com/article/10.1007/s00382-018-4102-x?wt_mc=Internal.Event.1.SEM.ArticleAuthorOnlineFirst The efficacy of methane is probably not directly linked to geoengineering but is an
