Oct Mon Oct 24 update: Planet3.0 best sums this story up (and articulates my discomfort):
"...if we were doing science and not politics, [this result] would be of no real consequence. Which means that when we pay attention to it, we are paying attention mostly to politics masquerading as science."This (Berkeley Earth Surface Temperature) is a partially-Koch-funded project, initially embraced by global warming delayers, which - now that its results indicate the measured warming is not just an "urban heat island" (UHI) artifact - has [not been well received in some skeptical quarters.]
I haven't been paying much attention, but it's getting a surprising amount of coverage from climate blogs - e.g. here (Class M), here, here, here, Mother Jones here.
From Class M:
"Because the [submitted BEST] papers haven't been peer-reviewed, there's no telling whether their failure to falsify the no-UHI effect will even be added to the literature. The general practice in scientific journals is to not pay too much attention to papers that confirm what we already know. "
