Much of Lindzen's opinion is an outlier in the climate science community, but he has made serious proposals for further investigation (Can water vapour feedbacks can be directly observed? Is ocean heat content tracking the models?) that have been the impetus for studies by others - though the results have generally not been supportive of his views.

One thing that Lindzen does demonstrate: if you are a public "skeptic" which actual credentials relevant to your concerns, and you can raise scientifically plausible questions about current models, people on "the other side" in the climate science debate will attempt to address them.
IMO a demonstration people convinced that there is some sort of conspiracy to suppress such opinion ought to keep in mind - the reason you don't see more such studies is that there aren't many such questions being raised.
No, the reason you do not see many such studies is because the government wont fund them. Hard to believe that we are only just now starting to analyze the changes in non-visible light during the solar cycle. We have been around for a few thousand years and are just now starting to wonder about non-visible light from the sun ? An amazing stupid species we are.
Or, we might add, a dearth of true scientists competent and ethical enough to pursue such questions.
Dogmatic AGW acolytes need not apply.
