Roy Spencer's ISH population adjusted discoveries

Readers recall that I carried a guest post from Dr. Roy Spencer on what he learned from analysing the CRUTem3 data: Spencer shows compelling evidence of UHI in CRUTem3 data. Now he has turned his attention to what I consider a better data set – the ISH data set, and comparing it to CRUTemp3 the…
