“The documents will undoubtedly raise questions about the quality of research on some specific questions and the actions of some scientists. But the evidence pointing to a growing human contribution to global warming is so broad and deep that the hacked material is unlikely to erode the overall argument. “
Nothing will be allowed to stand in the way of Global Warming, not even the truth.

HI Andy,
Yep, what was written below is all me, but it was purely on background, please don't quote
anything I said or attribute to me w/out checking specifically--thanks.
Re, your point at the end--you've taken the words out of my mouth. Skepticism is essential
for the functioning of science. It yields an erratic path towards eventual truth. But
legitimate scientific skepticism is exercised through formal scientific circles, in
particular the peer review process. A necessary though not in general sufficient condition
for taking a scientific criticism seriously is that it has passed through the legitimate
scientific peer review process. those such as McIntyre who operate almost entirely outside
of this system are not to be trusted.

I'm copying this to Tim, in hopes that he can shed light on the specific data assertions

I'm going to blog on this as it relates to the value of the peer review process and not on
the merits of the mcintyre et al attacks.
peer review, for all its imperfections, is where the herky-jerky process of knowledge
building happens, would you agree?
