According to today's Electricity Daily, there's a paper currently
undergoing peer review for Science that will surely be of interest to
some here.

The paper is by David Keith of Carnegie Mellon U and six or so
colleagues. The scientists suggest the possibility that "the climatic
response to extraction of wind power and to CO2 concentrations is
roughly linear". The theory that large-scale wind power might very well
increase global warming "will sicken many greens", the trade paper
predicts. Here's some details: "Large-scale use of wind power can alter
local and global climate by extracting kinetic energy and by modifying
turbulent transport in the atmospheric boundary layer. [Keith et al]
explored the climatic impacts of extracting 3-20 TW of electricity with
a suite of numerical experiments using two independent atmospheric
[global circulation models] and two paramatizations of the wind-turbine
arrays. Wind power has a negligible effect on global-mean surface
temperature but, at continental scales, the average magnitude of
climatic change due to wind power can be significant when compared to
the reduction in climatic change achieved by the substitution of wind
for fossil fuels."

I have to say that's bullshit.

The capture hight of wind-farms is 30m in the air. This is inconsequential
compared to global weather patterns.

I went to the site (http://www.electricity-daily.com), and read the
following:

"Written in full-blown science-speak, a new paper now circulating for review
suggests that large-scale wind power might very well increase global
warming, a theory that will sicken many greens"

Ooohh, full-blown science-speak.

Of course you can't access the paper unless you are a member of Electricity
Daily

Steve, are you man enough to provide access to the original paper, so we can
appraise it without the spin?
