Spring 2005 sets new record for Arctic ozone depletion

[x-y-no]

Sorry - don't have an online link, but this was published in the latest issue of "Nature."

We had an exceptionally strong Arctic vortex this winter, which would account for this record level of ozone depletion (the recipe for ozone depletion is adding sunlight to extremely cold air well-mixed with halogens.)

This may or may not be related to global warming - some models show an enhanced polar vortex as an effect of warming, others do not.

I have always believe that humanity is not going to dissappear because an asteroid or a terrible earthquake, or any other natural disaster. Humanity will kill itself by its actions, and I surely believe there is nothing to stop it. People care more about to have a comfortable present and don't see or seem to care about how our actions are shaping a hostile future.
