1873 vs 1874. Hadcrut4.

Three claims for the “global historical surface temperature anomalies” of the January-to-December calendar years 1873 and 1874 as per HadCrut4 version 4·0·0·0.

1st claim.  The global temperature anomaly of 1873 is between {0·70(±0)ºC more than} and {0·55(±0)ºC less than} the global temperature anomaly of 1874.
2nd claim.  The global temperature anomaly of 1873 is between {0·40(±0)ºC more than} and {0·25(±0)ºC less than} the global temperature anomaly of 1874.
3rd claim.  The global temperature anomaly of 1873 is between {0·16(±0)ºC more than} and {0·18(±0)ºC less than} the global temperature anomaly of 1874.

The monthly series entails the 1st claim. The annual series entails the 2nd claim. The “decadally smoothed” annual series entails the 3rd claim. Which claims are true? Which claims are false? Which claims are neither true nor false?  Alternative link for version 4·0·0·0.
