NOAA, January 1998. For land and ocean surfaces combined, the average global temperature of the calendar year 1907 is 0·50ºC below the average global temperature of 16·50ºC for the thirty calendar years from 1961 to 1990, such that the annual global temperature of 1907 is 16·00ºC, which is the lowest annual global temperature for any calendar year from 1900 to 1997.
NOAA, January 2017. For land and ocean surfaces combined, the average global temperature of the calendar year 2016 is 0·94ºC above the average global temperature of 13·9ºC for the one-hundred calendar years from 1901 to 2000, such that the annual global temperature of 2016 is 14·84ºC, which is the highest annual global temperature for any calendar year from 1880 to 2016.

1892. HadCrut4.

Six claims for the global historical surface temperature anomaly of the January-to-December calendar year 1892, which:-

1st claim.  “Could be as low as, but is no lower than, -0·72ºC.
2nd claim. Could be as low as, but is no lower than, -0·60ºC.
3rd claim. Could be as low as, but is no lower than, -0·46ºC.
4th claim. Could be as high as, but is no higher than, -0·20ºC.
5th claim. Could be as high as, but is no higher than, -0·32ºC.
6th claim. Could be as high as, but is no higher than, -0·31ºC.

The monthly series of HadCrut4 version 4·0·0·0 entails the 1st and 4th claims. The annual series of HadCrut4 version 4·0·0·0 entails the 2nd and 5th claims. The annual series of HadCrut4 version 4·0·0·0decadally smoothed by the application of a 21 point binomial filter entails the 3rd and 6th claims. Alternative link for HadCrut4 version 4·0·0·0.
