“Canadian Scientists Shoot Giant Hole in Global Warming?”

Wow, this is really "cool." One of the key studies on global warming (MBH98) has apparently been smacked down by a new report that shows huge flaws in the original. Steven McIntyre and Ross McKitrick claim that MBH98 was plagued with mathematical errors, miscalculations, faulty assumptions, and a number of other long and unpleasant words.

Read the story on MIT's Techology Review, which is a follow-up to an earlier column, Medieval Global Warming. Then, if you're feeling particularly smart, scan through M&M Project Update and read the PDF version of their report.

It's a lot of reading, and a lot of science, but I found it very interesting. Here's a good quote from the actual report:

On the basis of corrected and updated data, 15th century values are higher than those in the 20th century, contradicting the MBH98 conclusion of a unique late 20th century climate.

I'm surprised to say that I did not find this on one of Brian Carnell's sites, like OverPopulation.com, where these kinds of things are talked about all the time. Rather, I found it on Clark's new site, Waking Up Costs. Thanks, Clark, that was a good read.
