Warning of unprecedented heatwaves as El Niño set to return in 2023
The Guardian Environment
The return of the El Niño climate phenomenon later this year will cause global temperatures to rise “off the chart” and deliver unprecedented heatwaves, scientists have warned.
Early forecasts suggest El Niño will return later in 2023, exacerbating extreme weather around the globe and making it “very likely” the world will exceed 1.5C of warming. The hottest year in recorded history, 2016, was driven by a major El Niño.
It is part of a natural oscillation driven by ocean temperatures and winds in the Pacific, which switches between El Niño, its cooler counterpart La Niña, and neutral conditions. The last three years have seen an unusual run of consecutive La Niña events.
California’s rainstorm hell ‘among the most deadly disasters in our history’
The Guardian US
As more dangerous storms bear down on California, the state is only just beginning to grapple with the destruction and death left by weeks of extreme weather that wreaked havoc in nearly every region from the northern coast to Los Angeles.
The series of storms that have pummeled California since late December have killed at least 19 people, brought hurricane force winds that toppled trees and power lines, cutting energy to thousands, and flooded roads and rivers, covering swaths of land in dense mud and debris that stretches for miles. Entire communities have been forced to evacuate while road closures and power disruptions left some rural regions isolated and almost cut off from the outside world.
