HadCrut annual comes with an estimated 2017 value, with a confidence range.
Top three stuff, new record possible.
Interesting that the very provisional "predicted" year-end value for HadCRUT is currently showing as the 4th consecutive record year...
2014 +0.575
o C
2015 +0.760
o C
2016 +0.773
o C
2017 +0.820
o C
As each of the three monthly anomaly values so far this year (+0.740
o C ; +0.847
o C ; +0.876
o C ) was considerably cooler than the equivalent value(s) from 2016 (+0.906
o C ; +1.070
o C ; +1.069
o C ), for this "projection/prediction" to be realised, the remainder of the year could get interesting.
To equal the 2016 temperature anomaly, the remaining 9 months of the year would need to average about 0.065
o C warmer than that clocked up for April - December 2016 (which was ~ +0.694
o C).
To get to the "predicted" value, the April - December average for this year would need to be about 0.125
o C warmer than the equivalent from last year.
I would expect that the teams from the Met Office and the CRU are looking at the ENSO figures with some interest. NOAA figures put the July - December 2016 average anomaly in the 3.4 region at -0.71
o C, but the Mar-April average this year is +0.3
o C, and there currently seems to be about a 50% chance that an el Nino could develop later this year. (Although one would certainly expect some lag in the relationship.)
