Ferrari Mailing List: Re: Women should stop admiring Ferrari owners

Actually, CO IS one of them.  CO is carbon monoxide, and can cause symptoms at 
100 parts per million.  At 667 ppm, up to 50% of the blood can be made 
incapable of carrying oxygen.

Of course, though, CO isn't what you're talking about - that's CO2 (carbon 
dioxide).  Interesting story on Wikipedia about Venus's atmosphere (about 60% 
CO2).  http://en.wikipedia.org/wiki/Venus#Atmosphere.  Its damn hot, full of 
CO2, and apparently much hotter than it used to be.

Of course in our atmosphere, the absolute concentration of anything is pretty 
meaningless - the change is the interesting thing.  And a 35% delta is pretty 
big.  Sure, there's a lot of hype about this, and lots of people trying to make 
money on it (that's how the economy works, and most people like the free 
market).  But the science isn't driven by hype or money.  It is mostly a bunch 
of tenured professors doing what they do.  Sure, there is some level of 
following what is hot involved in getting grants, but that doesn't invalidate 
the data.
