Recently published observational and theoretical research suggests that climate sensitivity might be considerably less than that exhibited by all of the climate models taking part in the most recent IPCC summary. It is argued that climate models’ hypersensitivity could be the result of confusion between cause and effect when researchers analyze natural climate variability, which then finds its way into the models through improper cloud parameterizations.
