Before this gets into a brawl regarding the definitions of PPO2 and
PPCO2 I'd like to step back a bit and add........ this should not be a
discussion about "...global warming...." That was a term used initally
by the press when some scientest discovered a climatic anomoly that
just happendend to be an increase in temprature. The idea is simply
not the whole place getting hot. Thats just part of the picture as we
know it now............. its more accuarte to say "global climate
change" or "climate change" cause its getting dryer, hotter, colder,
wetter, longer, shorter in all sorts of places. But some think even
after the death groans the earth will eventially just be cooked.

Why is everyone calling it Global Warming? The press called it that
when the reporter couldnt understand the scientific's explination an
dfigured nowbody else could either. Thats pretty typicall. And thats
why ya see seminars titled: How to give technical informatin to non-
technical audiences. Then the Republicans grabed it and started
beatting that drum and would not change for fear of confusing the
squak boxes at Fox Network. Cause now there is all sorts of newer info
that says we just aint cooking uniformilly. SOme places are getting
colder. Ahh, now we can use that as support to counter the Global
Warming claim. See, if the the world is suppose to be geting warmer
and I find an exception, every normal scientest and country in the
world is wrong! See, I can use an exception to build an argument. So
we should never change the term to Global Climate Change. That would
neuter the Republican's rant.
