The National Oceanic and Atmospheric Administration has announced that 2015-2016’s 15-month, record-breaking El Niño is over, with a 75 percent possibility for La Niña conditions to form in the Pacific Ocean by the end of autumn.

"There’s nothing left," explains NOAA Climate Prediction Center deputy director Mike Halpert. "Stick a fork in it, it’s done."

This past cycle saw record-breaking temperatures around the globe, making 2015 the hottest year on record, and setting up 2016 to break that record. It also contributed to a record hurricane season in the Pacific, and droughts in Africa and India. Massive coral bleaching and numerous red tide events, caused by high water temperatures, marred the year as well.

In an unprecedented event, two hurricanes have formed at the same time in both the Atlantic and Pacific Oceans in the month of January, with the Pacific storm, breaking a record as such, and also exhibiting an unusual proximity to the equator. This is also the first time on record that off-season hurricanes have formed in both the Atlantic and Pacific in the same year; to have both form in the same month adds to the extreme unusuality of the event.

The eastern half of North America is definitely not dreaming of a white Christmas this season: the forecast is calling for record-breaking warm temperatures this week, with some regions to see temperatures 35º Fahrenheit (19ºC) above normal. Temperatures are expected to briefly dip over Christmas itself, but are expected to rise again for the remainder of the year.

The National Oceanic and Atmospheric Administration has released their temperature data for the Pacific Ocean, confirming that the current El Niño is the hottest ever recorded. Unfortunately, this also may guarantee that the current cycle will result in a prolonged La Niña event in the later half of 2016.

The previous record-holding El Niño period was the week of November 26, 1997, where surface temperatures were recorded at 2.8°C. The new record, for the week ending November 09, 2015, hit an even 3.0°C above normal – over seven percent higher than the previous record. This will result in more severe weather patterns in the US southwest, and possible drought conditions in Australia and Indonesia.
