Also a word in McPherson's defense. I'm not willing to just throw him to the wolves. McPherson has a doctorate in Ecology and the Environment, he is a Professor Emeritus from the University of Arizona.
The lukewarmer who wrote the article that KJ posted taught undergrad Earth Sciences as a graduate student while working on his masters in hydrogeology.
He worked briefly on a survey conducted by the Wisconsin Dept. of Natural Resources. He has since been a blogger.
You need to watch your sources.
Also, in his attack on McPherson, he was just making pigeon chess attacks, without actually addressing any of the claims by McPherson, no argument was given. Just crap on the board, kick over the pieces, then fly away claiming victory.
Now, I don't really know enough about McPherson's claims to address them, but I do know the author of the article didn't.
And some of what the author claimed was outright untrue, without providing any documentation to support his accusations.
He also made statements like, other scientists say he is wrong. WTF? About what? In what way?
You are just posting crap that you uncritically accept, because you don't like the message.
But then, if you guys had any critical thinking skills you wouldn't be trying to deny what has become the obvious.

The level of injustice and wrong you endure is directly determined by how much you quietly submit to. Even to the point of extinction.
