I think one of the more interesting phenomenon that occured about 10mya
was the closing of the straits between north and south america. You can
still see the pacific trying to send its warm water over to the other
side http://orbit-net.nesdis.noaa.gov/orad/sub/crblrg_sstanom6m.html
. It would have been very interesting to see the storms produced from
the tropical waves from africa meeting the warm waters from the pacific!
Earth geology and weather is very dynamic. There are some models (and
some geologic evidence) that show that some of the most dynamic changes
occur very quickly. A few years back there was research that showed
that the earth was indeed a snowball and that the change occured very
rapidly about 100y. That is the most frightening to me! I don't even
own a good pair of gloves!

I believe that most weather predictions are accurate for a warming
period. There is little that man did and can do to prevent it. I would
like to breath clean air however. I would like to see a reduction in
acid rain. These and other events/issues are man made.
