But it also does not have to be released at surface to be effective--release it from remote mountain tops or otherwise at elevated levels. Also, the study here was for a rather high loading--if the world would get busy on emissions reductions and the desired effect were to shave off peak warmin

Thanks Alan. Yes, more investigation on this is needed, as noted in my blurb as well. I'm adding the lead author to this discussion in the event that she might be interested in participating in this discussion and is not in any of the lists. Below is a snippet from the paper (p. 57580 that I thi

But it's nasty stuff.  Please keep in mind the last sentence of the abstract, "However, our assumption that the rate of COS uptake by soils and plants does not vary with increasing COS concentrations will need to be investigated in future work, and more studies are needed on the prolonged expos

Dear Colleagues, FYI, if you haven't heard or seen this. Carbonyl Sulfide (COS) aerosols released from the earth's surface and in models appear to have a cooling impact similar to SO2 released in the stratosphere. More research on the potential impacts of increased COS released from the surface i
