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.

1884. HadCrut4.

Three claims for the global historical surface temperature anomaly of the January-to-December calendar year 1884 as per HadCrut4 version 4·0·0·0.

1st claim.  “The anomaly is -0·390(±0·240)ºC.
2nd claim. The anomaly is -0·395(±0·135)ºC.
3rd claim.  The anomaly is -0·315(±0·075)ºC.

The monthly series entails the 1st claim. The annual series entails the 2nd claim. The annual series decadally smoothed by the application of a 21 point binomial filter entails the 3rd claim. Alternative link for version 4·0·0·0. Question: The anomaly for 1884 is what number of degrees centigrade?(± what number of degrees centigrade?(± what number of degrees centigrade?(± what number of degrees centigrade?))).
