1888. HadCrut4.

Three claims for the global historical surface temperature anomaly of the January-to-December calendar year 1888:-

1st claim.  “It could be as low as, but no lower than, -0·55ºC, or it could be as high as, but no higher than, -0·06ºC.
2nd claim. It could be as low as, but no lower than, -0·44ºC, or it could be as high as, but no higher than, -0·17ºC.
3rd claim. It could be as low as, but no lower than, -0·41ºC, or it could be as high as, but no higher than, -0·27ºC.

The monthly series of HadCrut4 version 4·0·0·0 entails the 1st claim. The annual series of HadCrut4 version 4·0·0·0 entails the 2nd claim. The annual series of HadCrut4 version 4·0·0·0decadally smoothed by the application of a 21 point binomial filter entails the 3rd claim. Alternative link for HadCrut4 version 4·0·0·0.
