However, for the low sensitivity obtained from the actual climate system, we see that sensitivity is narrowly constrained to about 0.5C, and strongly implies that there is little to be concerned about.It seems to me like this should be fairly big news. Lindzen is well known, with a long track record, from a relatively prestigious institution, with astounding results.
In a normal field, these results would pretty much wrap things up, but global warming/climate change has developed so much momentum that it has a life of its own – quite removed from science. One can reasonably expect that opportunism of the weak will lead to efforts to alter the data (though the results presented here have survived several alterations of the data already).
But there is remarkably little buzz. There's no mention that he's going to submit these results in a paper for peer review. The global warming skeptics don't seem to have much noticed these appealing results. The global warming believers haven't bothered to refute it.
The quiet seems strange to me. The debate has never lacked volume before.
