oh, and one more thing....while i'm still on my soapbox:
the ozone hole over antarctica. it was discovered in 1985. we have been monitoring ozone in the atmosphere for only 40 years. SO HOW IN THE HELL CAN WE SAY THAT IT ISNT PERFECTLY NORMAL BASED ON ONLY 40 YEARS WORTH OF DATA?!?!?!?
just curious.

Changes may spark conflicts between nations over resources, but unless warming somehow releases vast quantities of methane and CO2 into the environment along with the huge increases already expected in water vapor, I don't see a real species threathening change.
My primary concern is over the world's oceans. We have already caused the creation of tens of thousands of square kilometers of sterile, dead seas around the edges of our continents--where coincidentally are located the world's richest collections of marine life--and if we continue such pollution induced changes (i.e., if those sterile areas continue to grow at their current rate), it won't be long before we begin to threaten the very air that we breathe. The simple fact is that if the oceans go then we go.
