Some people were wondering if HadCRUT4 would come out on top. It could be argued that it did. Just. The Met Office is being cautious, saying it is too close to call, which is fair enough. From their press release - my emphasis:
26 January 2015 - Provisional full-year global mean temperature figures show 2014 was one of the warmest years in a record dating back to 1850.
The HadCRUT4 dataset (compiled by the Met Office and the University of East Anglia's Climatic Research Unit) shows last year was 0.56C (±0.1C*) above the long-term (1961-1990) average.
Nominally this ranks 2014 as the joint warmest year in the record, tied with 2010, but the uncertainty ranges mean it's not possible to definitively say which of several recent years was the warmest.
Colin Morice, a climate monitoring scientist at the Met Office, said: "Uncertainties in the estimates of global temperature are larger than the differences between the warmest years. This limits what we can say about rankings of individual years.
"We can say with confidence that 2014 is one of ten warmest years in the series and that it adds to the set of near-record temperatures we have seen over the last two decades."
WUWT and GWPF - disinformers lie through their teeth!
There is no such hesitation or caution among the climate disinformers though. Professional liar denier Anthony Watts claims, wrongly, that:
"UK Met Office says 2014 was NOT the hottest year ever due to ‘uncertainty ranges’ of the data".
That's wrong. The UK Met Office did NOT say 2014 was not the hottest year ever. It's one thing to say it's too close to call even though the numbers show it the hottest. It's quite another to say that it was NOT the hottest year ever. Just how desperate must he be feeling. Honestly, you've got to wonder if Anthony Watts can lie straight in bed!
His headline was above a "press release" by the GWPF, which is an anti-mitigation lobby group from the UK. In the body of the release, David Whitehouse, who I guess is paid to tell fibs, wrote:
Quoting the temperature to one hundredth of a degree and the error on that measurement to a tenth of a degree is not normal scientific practice. It is against normal scientific practice to have an error of the measurement larger than the precision of that measurement. This means that most scientists would have rounded the data so that it was 0.6 +/- 0.1 °C. If this is done to the HadCRUT4 dataset it is even more obvious that there has been a warming “pause” for the past 18 years.
That's not right or correct or accurate. The Met Office provides data to three decimal places and reported it to two decimal places. 0.563C was the reported median and 0.529 and 0.600 were the lower and upper bounds at the 95% confidence interval.
I guess when the disinformers can't claim that an ice age is imminent, muddying the hottest year with a pause is the next best thing.
I'm very pressed for time this week but will just add two more things. First a chart of HADCRUT4 - click to enlarge it:
