Hot of the press tonight...
Global temperatures in January rose to 0.51C above the 30 year running mean according to UAH satellite data, up sharply from an anomaly of 0.21C in December.
This makes it the second warmest January on satellite record, behind January 2010.
It equates to a global temperature of approximately 0.763C above the more standard 1961-1990 measure.
The rise comes as quite a surprise, especially considering El Nino-Southern Oscillation (ENSO) indicators in the tropical Pacific remain at neutral levels.
