A detailed, long - term ocean temperature record derived from corals on Christmas Island in Kiribati and other islands in the tropical Pacific shows that the extreme warmth of recent El Niño events reflects not just the natural ocean - atmosphere cycle but a new factor: global warming caused by human activity.

The CPC officially considers it an event when the sea surface temperatures in a key region of the ocean reach at least 0.5 °C, or about 1 °F, warmer than average.

Hurricanes, the largest and most damaging weather events, peak in late autumn, when winds coming off the coast of West Africa meet thunderstorms clustered over the warm tropical ocean.

Forecasters believe the current Kelvin wave and the already warmer ocean temperatures, signal that the El Niño is going to persist, which was another factor in officially declaring an event.

In the Pacific and Indian oceans, for example, warming water has already kicked off a coral bleaching event.

When we have a «blue ocean» event, that will greatly increase warming all on it's own — adding as much heating as all our emissions since the beginning of the industrial age!

«There is an event documented in sediments from 55 million years ago called the Paleocene Eocene Thermal Maximum, during which (allegedly) several thousand Gton C of methane was released to the atmosphere and ocean, driving 5 ° C warming of the intermediate depth ocean.

However, if one downweights these two events (either by eliminating or, as in Cane et al» 97, using a «robust» trend), then an argument can be made for a long - term pattern which is in some respects more «La Nina» - like, i.e. little warming in the eastern and central equatorial Pacific, and far more warming in the western equatorial Pacific and Indian oceans, associated with a strengthening, not weakening, of the negative equatorial Pacific zonal SST gradient.

A study recently published in Nature suggests that an extreme global warming event 56 million years ago known as the Palaeocene - Eocene Thermal Maximum (PETM) was driven by massive CO2 emissions from volcanoes during the formation of the North Atlantic Ocean.
