Well, their paragraph on Climate Science is a rather astonishing take on the APS Workshop. Their paragraph on Climate Change seems to come from the Guardian. Their statement on Climate Action reiterates their rather crazy statement in 2007
Apart from the issue that no one on the POPA seems to understand any of these issues beyond a superficial level (after Koonin and Rosner departed from the POPA), and that their statements are naive and unprofessional, here is my real problem with this. This is an egregious misuse of the expertise of the APS. Their alleged understanding of issues like spectroscopy and fluid dynamics are not of any direct relevance to the issues they write about in this statement. The statement is an embarrassment to the APS.
Either reform is required, or an alternate organization.
