Settled science: "It is clear that not even the 15 AGU members set to write this statement agreed, since one of their members (Pielke) has written a dissenting statement"

AGU Statement on Climate Change | Climate Etc.

Of the two statements, I vastly prefer Roger Pielke Sr’s statement,since he discusses the complexity of the issue and the uncertainties.

That said, I will once again question why AGU or any other professional society is issuing statements on this topic. IMO, AGU’s statement is one of the worst I’ve seen from a professional society on this topic, in particular its title ‘Human-induced climate change requires urgent action.’ This is an explicit statement of advocacy, that goes well beyond what the IPCC has said (and is expected to say in the AR5; we will see).

What really irks me about this statement is that I am a member of the AGU, and therefore this statement is implicitly speaking for me. It is clear that not even the 15 AGU members set to write this statement agreed, since one of their members (Pielke) has written a dissenting statement. The words ‘uncertainty’ or ‘debate’ are not used in the statement, leaving no wiggle room for them to pretend that this statement accounts for the range of perspectives in the AGU (or even within the writing committee), or the uncertainties.
