Climatologist, author, and former NASA scientist Dr. Roy Spencer offers ten good skeptical arguments against global warming. Raw Story published a response to this via The Guardian, if you’d like to read it.
As suggested by a friend, I’m following up my Top Ten bad global warming arguments list with a Top Ten good arguments list. These are in no particular order, and I might have missed something important.
These ten were just off the top of my head….there’s no telling what might be lingering deeper in my brain.
I have avoided specific alternative causal mechanisms of natural climate change, because I view them individually as speculative. But taken as a whole, they represent a class of unknowns that can’t be just swept under the rug just because we don’t understand them.
For some reason, all of these ended up being phrased as questions, rather than statements.
1) No Recent Warming. If global warming science is so “settled”, why did global warming stop over 15 years ago (in most temperature datasets), contrary to all “consensus” predictions?
2) Natural or Manmade? If we don’t know how much of the warming in the longer term (say last 50 years) is natural, then how can we know how much is manmade?
3) IPCC Politics and Beliefs. Why does it take a political body (the IPCC) to tell us what scientists “believe”? And when did scientists’ “beliefs” translate into proof? And when was scientific truth determined by a vote…especially when those allowed to vote are from the Global Warming Believers Party?
