The EPA recently issued a Notice of Proposed Rule Making (NPRM) proposing to regulate six greenhouse gases (GHG) to counter global warming. The White House responded with a critique that basically pokes holes in the NPRM and the Technical Supporting Document (TSD).
The White House document is a good read because it lays out (perhaps unintentionally) all the reasons we should not be taking the UN/IPCC alarmist hype over climate change seriously.
There is a bit of a puzzle here, though. The authors of the White House memorandum, like the EPA, are part of the executive branch of the government. And, the administration speaks with one voice, right? So, the Obama administration's pursuit of caps on GHGs while, at the same time, issuing a memo that undercuts the reasons for having such caps seems non sequitur.
