El Niño ends with uncertainty over cooler future
The powerful El Niño weather event which along with climate change has helped push global temperatures to new highs, has ended, say scientists.
The Australian Bureau of Meteorology says the Pacific Ocean has “cooled substantially” in the past week.
This naturally occurring episode that began last June brought warmer waters to the surface of the Pacific, adding extra heat to the atmosphere.
But what happens next is uncertain, say researchers.
A string of recent global monthly high temperature records has led some scientists to fear that the world could be tipping into a new phase of even faster climate change.
Scientists say that the months after the end of El Niño will give a strong indication as to whether the recent high temperatures are due to accelerated climate change or not.
Every few years, the onset of El Niño brings dramatic change to weather in many parts of the world.
