Plankton Can Make Clouds To Block UV

NotWallaceStevens writes "This article on Science Daily describes how plankton can create clouds in response to seasonal variations in UV radiation from the sun by producing a chemical called dimethylsulfoniopropionate (DMSP). This was a long term study based on data going back to the 1950s collected in the Sargasso Sea. One of the researches theorizes that the process could slow global warming."

    ..that plankton are contributing to the `acid rain problem'?

    1. Re:Does this mean.. by amide_one · · Score: 3, Interesting

      DMS does get oxidized, eventually, to sulfates (i.e., one of the acids in 'acid rain'). Is this important? Depends on how much is being produced this way, obviously, but according to this estimate the overall sulfur emission from oceanic sources (plankton, etc.) is about 20% of the emission from human activities (globally; it's more like 10% in the N. hemisphere, much higher anthropogenic emissions - mostly coal burning).

      So the evil death plankton's sunscreen is some kind of factor in acid rain, but not the biggest one.

      DMS (a very stinky volatile substance, making rotten cabbage to smell like rotting cabbage) gets oxidized to DMSO (odorless poorly volatile hygroscopic liquid). DMSO likes to stick to water molecules. Tthe resulting clump has lower vapor tension than water droplet - so the wet DMSO droplet starts growing.

      DMSO is non-acidic. It may get broken down to methansulfonic acid eventualy (through dimethtlsulfone) but this is oxidative degradation is rather slow process. I think DMSO would rain out much sooner than that. I think the net contributing effect to acid rain is close to zero.

    Earth, a planet that some say has maintained a rich biological diversity for hundreds of millions of years, has built in mechanisms to stabilize environmental conditions!

    In a shocking new report, it was discovered that perhaps this global warming thing is a bunch of nonsense. The amount of damage we do to the atmosphere is nothing compared to what the variety of stellar material, volcanic eruptions, and biological processes have done in the past several million years. After each disturbance, the earth has maintained balance by compensating for disastrous change in the chemical composition of the atmosphere. Some of these adaptive processes were geological, but some were also biological.

    It's almost as if life on earth was designed or grew to accustom themselves to earth's natural environment. In fact, the biological organisms have even changed the environment to make it more habitable for other biological organisms.

    Just like bacteria in the environment maintain a balance by consuming extra resources, or limiting growth due to the absence of resources, the earth as a whole behaves in a similar way. When there is too much of something, it gets consumed at a greater rate. When there is not enough, it gets consumed at a slower rate. In the end, everything has a balance that is maintained within precise criteria.

    In other news, free markets really work, and are the most effective way for distributing resources fairly due to a similar process called "supply" and "demand". Also, it was discovered that profits weren't evil, and that by allowing corporations to own land and profit therefrom, the land is taken better care of and more efficient than wilderness.

    Unfortunately, you must subscribe to get more than just the abstract.

    DMSP and DMS cycles are more complex than this brief article reports. DMSP is produced by algae, and some DMSP is broken down to DMS by algae as well. However, bacteria seem to have a major role in breaking down DMSP to DMS, as well as to another compound, methanethiol, that is not released into the atmosphere in large amounts.

    Interestingly, the genome of a bacterium that carries out both pathways of DMSP degradation is being sequenced. Hopefully this will soon allow us to find more about these two competing fates of DMSP. If you really want more information on this bacteria, you could read a discription paper.
