Judy Curry recently noted that Phil Jones’ 2014 temperature index (recently the subject of major adjustments in methodology) might be a couple of hundredths of degree higher than a few years ago and alerted her readers to potential environmental NGO triumphalism. Unsurprisingly, it has also been observed in response that the hiatus continues in full force for the satellite records, with 1998 remaining the warmest satellite year by a considerable margin.

Equally noteworthy however – and of greater interest to CA readers where there has been more focus on model-observation discrepancy   – is that the overheating discrepancy between models and surface temperatures in 2014 was the fourth highest in “recorded” history and that the 5 largest warm discrepancies have occurred in the past 6 years.  The cumulative discrepancy between models and observations is far beyond any previous precedent.
