July through September of 1881 saw the hottest temperature on record in Europe and in parts of the US, including Washington DC (h/t to AndyDC.) HadCRUT shows those three months as being among the coolest on record.
We also know that glaciers at both poles were rapidly melting during the coldest period in the HadCRUT record, and rapidly forming during the 1960s and 1970s. Phil Jones admitted that his error is half a degree, which comprises the entire trend.
