Ken et al, adding Tom Goreau (who probably is well aware of DMS)
Thanks for the response, especially your below using the term “DMS”.
I spent much of the day chasing that word and found an amazing amount
on the subject - much in the last few year.. There are clearly many things
still to learn but climate modelers seem now able to pretty well predict the
dozen or so chemical transformations that happen over a day or so as DMS
changes to encourage clouds.
I never found a paper saying that DMS could be a practical method for
increasing albedo, but I’m now pretty sure that’s on some minds. Being
natural, it should solve a lot of practical problems in carrying out simple
cloud albedo experiments.
I have followed the Sargasso biomass possibility for several years.
There are people doing something similar - even including biochar aspects - but
I now have more interest in DMS. Maybe can be coupled with biochar.
More coming, hopefully.
