Global Warming and Mass Extinctions

[mariusromanus@aol.com]

About his Permian-Triassic thread... If it hasn't been mentioned 
already, everyone go and buy October's Scientific American. The article 
of interest is entitled Impact from the Deep, and it discusses many of 
the questions I've seen come up in the Triassic-Permian thread... and 
not just for the Permian extinction, but also for the end Triassic and 
the end Devonian and the end Ordivician. A nice comparison with the KT 
is presented as well, showing without a doubt, that the mechanisms for 
the KT vs the mechanisms of the other Big 4 were completely different.

And just my two cents here... but this theory is a winner. I complained 
many times about over generalizing these extinction events... that is, 
naming the bolt from the heavens the reason for all of them.... You 
know... Blame it on an asteroid/comet... It used to be the popular 
thing to do.

I guess after you really take a cold hard look at what evidence 
actually exists and what said evidence is actually saying, things just 
end up not as simplistic as most thought.
