Holdren’s Bi-Polar Vortex: Claimed global warming was responsible for colder winters — But ‘4 recent studies all contradict the global warming/polar vortex connection’
New claim: Holdren was simply expressing his “personal opinion”
CEI: 'Holdren’s claim of a growing body of evidence on this issue was simply false. In fact, from September 2013 on, three peer-reviewed studies appeared debunking the notion that polar warming had led to an increase in what are known as winter blocking episodes—situations where extremely low temperatures become locked in for exceptionally long periods of time. That was why, in April, we filed a formal request for correction with OSTP under what’s known as the federal Data Quality Act. After we filed our petition , by the way, yet a fourth study appeared disputing the global warming/polar vortex connection. Yesterday, shortly before OSTP’s 90-day deadline for responding to correction requests, we received the agency’s denial (see below). OSTP claims that Holdren was simply expressing his “personal opinion” rather than any “comprehensive review of the scientific literature”. On its face, this response is shovel-ready nonsense.
