A few dynamists are kicking around the idea that the 1982-83 EL Nino -- a warming of the Pacific waters that altered climate worldwide -- might be involved, but so far the SST-ozone correlation has not been explained.
A dynamic explanation for the ozone hole suggests that there have been Antarctic ozone holes in the past and that they will develop again in the future -- although dynamists have little idea about how frequently they may recur.
Mahlman stresses that while he and other dynamists think that dynamics is important to the ozone hole, they still believe that CFCs are going to have a "monstrously large effect" on stratospheric ozone in the future.
And dynamists do think that chemistry is involved, to some degree, in the formation of the ozone hole.
The message from dynamists, and especially scientists like Mahlman, who has been studying ozone and the stratosphere for years, is that there is still much to learn.
