Our earlier posting of links to Dr John McLean's exposure of errors in the HadCrut temperature data relied on by the IPCC for its (mostly misleading) predictions, reminded us of the 2009 paper by Joseph D'Aleo and Anthony Watts that analysed the siting of temperature recording stations. That paper is worth reading again in 2018 as IPCC makes more scary predictions, continuing its line of alarmist forecasts which have still not come to pass.
