Sorry for the second post, and I don't mean to run away with your thread, but the connection to that last comment seems germane to me.
I came across this -- one of a growing number of such reports that have been coming out over the past couple of years:
EPA scientists complain about political pressure - Yahoo! News
This makes me think of an argument I had with someone recently on regulations concerning greenhouse emissions, etc.; who was of the opinion that such changes should be left up to "the market trends" and "consumer decisions"... never mind the fact that we're not dealing with philosophical abstracts, but are fast coming up against the inexorable laws of physics with such things.
If we can't pull our collective heads out of our collective rears and realize that, and look for the truth, rather than riding some hobby-horse (either way), we bloody well may not have a future.
And then there's always our dear presidential nitwit's plan to give up to 15
more years for such emissions to
peak before reducing them....
