The Australians are watching.

Early analysis of the warm SST in the North East Pacific is showing temperature anomalies exceeding 4 standard deviations above the mean. This warming began in 2013 and it has been suggested that this may be a new sort of phenomenon not seen before in modern records (

Agelbert NOTE: something very interesting is going on in the Pacific; the sea level is GOING DOWN! 

No, the fossil fuel industry didn't find some giant plug to pull and drain the giant ocean bathtub down a bit. 

That is an El NIŇO characteristic. They haven't seen that sort of thing so strongly since the 1997-98 strong El NIŇO. But what they fail to mention is that, since there is a LOT more water in the oceans now than in 1998, thanks the accelerated ice melt from Greenland and Antarctica, the sea level is going to get a rather large BOOST in some other part of the planet.

The month-average of sea level north of New Guinea has dropped to levels not seen since the ‘super El Niño’ of 1997/1998. An El Niño event occurs when sea surface temperatures in the central and eastern Pacific become sufficiently warm that the atmospheric circulation shifts resulting in weaker equatorial trade winds. Low sea levels north of New Guinea (a result of weak equatorial trade winds) are strongly correlated with Nino3.4, the El Niño index that relates best to Australian climate.


Dark Blue in graphic below is lower sea level: 


The Bureau of Meteorology declared 2015 an El Niño year in mid-May. Sea levels north of New Guinea have continued to drop sharply since then. The map at right shows the June 2015 SLA for the Australasian region, while the time-series below shows that the average for the region north of PNG  (boxed on the map) has only been lower once before since 1992 when satellite sea level observations commenced.

Low sea levels in the western equatorial Pacific are also strongly correlated with the strength of the Leeuwin Current. There is a two month delay between the sea level anomaly off Perth and the region north of New Guinea. The low sea level signal propagates southward along the west coast of Australia weakening the Leeuwin Current and causing water temperatures to be cooler.
