Dr. Roy Spencer: The wording is ambiguous. But the authors decided Pruitt meant “there has been zero warming” for exactly 20 years. They proceeded to evaluate this interpretation with a statistical analysis of the various satellite temperature datasets, as well as with climate models. The result is a peer-reviewed study which took less than one month to sail through peer review. Wow. If I only knew earlier that I could get peer-reviewed scientific papers by evaluating the silly climate claims made by politicians (Al Gore, Barack Obama, et al.) over the years. Oh, that’s right. I’m on the wrong side of the issue. The reviewers would have said, “C’mon, that’s a politician generalizing. You can’t get a peer-reviewed scientific paper out of that!”
Meteorologist Dr. Ryan Maue: 'A concerted effort has been made in recent years to discount the hiatus as an insignificant statistical artifact perhaps based upon bad observational data, or a conspiracy theory to distract the public and climate policymakers. Even acknowledging the existence of the “hiatus” is sufficient to be labeled as a climate change denier...Climate scientists still need to know how variability (natural and anthropogenic) in the climate system works to attempt to model its changes through time regardless of political inconvenience.'
A new paper has been published in the Analysis section of Nature called Reconciling controversies about the ‘global warming hiatus.’ It confirms that the ‘hiatus’ or ‘pause’ is real. It is also rather revealing.
Lindzen: "Doubling CO2 involves a 2% perturbation to this budget. So do minor changes in clouds and other features, and such changes are common. In this complex multifactor system, what is the likelihood of the climate (which, itself, consists in many variables and not just globally averaged temperature anomaly) is controlled by this 2% perturbation in a single variable? Believing this is pretty close to believing in magic. Instead, you are told that it is believing in ‘science.’ Such a claim should be a tip-off that something is amiss. After all, science is a mode of inquiry rather than a belief structure."
"The accumulation of false and/or misleading claims is often referred to as the ‘overwhelming evidence’ for forthcoming catastrophe. Without these claims, one might legitimately ask whether there is any evidence at all."
The study claims to have “proven that it is all but certain that EPA’s basic claim that CO2 is a pollutant is totally false,” according to a press statement put out by Drs. Jim Wallace, John Christy and Joe D’Aleo. Wallace, Christy and D’Aleo — a statistician, a climatologist and meteorologist, respectively — released a study claiming to invalidate EPA’s 2009 endangerment finding, which allowed the agency to regulate CO2 as a pollutant.
