Remember this one the next time it warms over a 10-year period: Warmist Andy Pitman--“Whether it did or did not warm in a 10-year period is utterly irrelevant to global warming"

George Pell: Cardinal Pell views on global warming rubbished by climate scientists | Crikey

On a claim that the world had “cooled slightly” since 1998, Pitman added: “Whether it did or did not warm in a 10-year period is utterly irrelevant to global warming which is a multi-decadal phenomenon described by climatological timescales. Pell has presumably been told this but his statements continue to confuse climate CHANGE with climate VARIABILITY.”

Professor Roger Jones, of Victoria University, was a lead IPCC author for a 2007 report on “New Methods and Characterisations of the Future.”

Jones reviewed a section of the speech where Pell said climate change variants including “water vapour multipliers, sunspot activities and cloud formation, as well as deforestation, soil carbon and aerosols” were not well understood, as were “asteroid and comet impacts, and variations in cosmic rays.”

Jones said: “It’s hard to tell whether this is Gish’s Gallop, Pell’s Polka or Plimer’s Passe Doble. It’s a variant of yeti spotting when you’re completely lost and trying to convince your followers you know what you’re doing.”
