Last week we exposed absurd errors, brutal adjustments and an almost complete lack of quality control (was there any at all?) in the key HadCRUT4 data. The IPCC’s favorite set is maintained (I’m feeling generous) by the Met Office Hadley Centre and the Uni of East Anglia’s CRU in the UK.
Finally the Hadley Met Centre team have replied to Graham Lloyd regarding John McLean’s audit. Wi thout specifically admitting he has found serious errors, they acknowledge his previous notifications were useful in 2016, and promise “errors will be fixed in the next update.” That’s nice to know, but begs the question of why a PhD student working from home can find mistakes that the £226 million institute with 2,100 employees could not. Significantly, they do not disagree with any of his claims.
