Although not widely distributed, I got so frustrated with an op-ed that
Lindzen was invited to submit to Newsweek several years ago that I put
together a point-by-point set of comments in response. Something like 19
points of difference for a one-page op-ed. Despite its length, I understand
it does get at least some hits. See

ding-newsweek-op-ed/

As a general comment, Lindzen's way of presenting his views can make them
hard to counter without getting into a more detailed discussions than most
non-scientists will read (or even appreciate the significance of). The
alternative form of response of trying to compare credibilities (pitching
greater credibility of IPCC or leading scientists, saying he takes money
from industry, etc.) runs into arguments he has supporting his credibility,
namely being at MIT and an NAS member, etc. and being a put upon victim of
the scientific establishment. And pushing for investigative reporter
articles requires them really getting into details, often beyond the level
of scientific expertise they want to get into.

Basically, to his credit (and unlike other Skeptics), Lindzen at least some
times offers alternative testable scientific explanations, sometimes with
claims of observations support, rather than just making wild assertions
(e.g., his high cloud explanation which took a good bit of scientific work
to get into; my view of the key problem was his rather hidden assumption, in
interpreting the satellite data, that the world is composed of unconnected
1-D vertical models and horizontal circulations make no difference in local
conditions). Ideally, he and his students would test his hypotheses (e.g.,
that higher surface temperatures lead to such strong convection that they
dry the upper troposphere, in terms of absolute rather than relative
humidity) by trying to formulate them for inclusion in a model and seeing if
they work or don't in detailed models of the world. He often rather
cavalierly leaves that to others, and when other scientists have taken that
on they have found that his hypotheses just don't work out (e.g., to explain
how orbital element variations can lead to glacial cycling if the climate
sensitivity is low, he has argued that relatively evenly spread forcings
like CO2 have a small sensitivity, but spatially distributed ones like
orbital elements generate a large response---plausible hypothesis, but then
one would expect that the present sulfate aerosol loading that is similarly
hemispherically and seasonally contrasting should have a really large
response compared to the CO2 response, and we don't see that--in
observations or models). It seems to me the really credible scientists
capable of responding effectively are those who have done these tests (a
number of them being in the GISS group), but it does require the scientists
and the listeners to devote a good deal of attention to detailed aspects of
the science--and there are just too many out there who won't listen to what
they don't want to hear. So, in many cases, it just seems much more
productive for scientists to go off and do good new science and leave
Lindzen as an unfortunate side-show while those who want to believe in his
comments invite him to all sorts of visible forums.

Looking at Lindzen's latest presentation in the UK, virtually all of his
slides would need to be commented on--starting with his statement that
"climate is always changing." Well, yes and no, he gives no bounds here, no
indication about how much change, and so on and on and on. Nice catch
phrases, and scientific responses would take many more words than he puts on
his slides. So, with a response, it is a lot more detail than a generalist
might really want to get into, and without a response, the event appears as
a prominent addition to his list of eminent groups he was invited to speak
to. Quite a challenge to overcome to broaden the appreciation of the very
difficult climate situation we are in.
