As far as global temperature goes it’s been a warmish start to the year, though not exceptional. This has led Carbon Brief in its three-monthly “state of the climate” report to predict that this year “is likely” to be as warm as the fourth warmest year since records began about 150 years ago. They say it could be as high as the second or as low as the 12th warmest.

Carbon Brief says, “The first three months of 2018 can give some sense of what to expect for the entire year.” But being based on a quarter of this year’s monthly measurements it could be described as either bold or foolish. Because the prediction is made without a good understanding of what has been happening to the global temperature in the past months it is probably more of the latter.

Nowhere is the Carbon Brief prediction is there any analysis of why 2018 got off to a warm start. Look towards the  Tasman Sea that has been adding to global temperatures since late 2017.

The water temperature in the Tasman Sea is well above normal –  6° C more than average for the start of December. New Zealand’s summer was the hottest on record, Tasmania had its hottest November-January on record. It was exceptionally warm on both sides of the Tasman, more than two degrees above average in December and part of January.
