“From DMSP munching microbes to global climate“. Anthony Watts has found a press release about a paper by Justin Seymour of The University of Technology Sydney. Did you know that “Observations show that microorganisms display a behaviour characteristic of larger animals.”? Dimethylsulfide (DMSP) helps marine microorganisms find food (or prey on those microorganisms)!
Seymour’s paper seems trivial from a climate science perspective, but this post seems to be just an opportunity to encourage commenters to rubbish a scientific paper that happens to mention climate change impacts.
“From DMSP munching microbes to global climate.” (WUWT, July 16, 2010)
Anthony is wrong here, either singly or doubly.
The DMS oxidizes in the atmosphere to become sulfur dioxide, which are cloud condensation nuclei.
Anthony should have mentioned that the effect (the CLAW hypothesis) would be to act as a NEGATIVE feedback loop, counteracting the effect of climate change. Increasing temperatures would increase the number of phytoplankton, which would produce more cloud condensation nuclei. The increased albedo would reflect more sunlight back into space.
Only one commenter caught on, referring to here.
