In our view, Daniel Greenberg's book review of 'The Climate Fix' by Roger Pielke Jr (Nature 467, 526–527; 2010) does a disservice to your readership by besmirching the integrity of the climate-research community.
Nature should have pointed out to its readers that Greenberg has served as a round-table speaker and written a report (see http://go.nature.com/otwvz2) for the Marshall Institute (see http://go.nature.com/4u9ttd).
We also object to Greenberg's misleading comments relating to our recently deceased colleague Steve Schneider. Greenberg reiterates a misinterpretation of a statement Schneider made in Discover magazine in 1989, which has since been corrected on numerous occasions. What Schneider crucially said, in addition to the phrase quoted in Greenberg's review, was “Each of us has to decide what the right balance is between being effective and being honest. I hope that means being both.” And that is exactly what Steve Schneider fought for all his professional life: effective communication of an honest and balanced assessment of the risks of climate change.
