The world’s leading weather organization is sounding the alarm about this year’s super El Niño, issuing its most certain forecast in the history of the organization. In an update issued early Thursday, the World Meteorological Organization predicted a “nearly 100% likelihood” that the El Niño will last through February. … Daniel Swain, a climate scientist at the University of California Agriculture and Natural Resources, says this El Niño will be so big, “with consequences that are so large, I’m not sure we fully understand them.” The intensity of the El Niño, Swain says, means that it may cause unexpected and extreme weather, and he cautions against making certain predictions about what, exactly, is going to happen over the next year. But the impacts, he says, will almost certainly be massive.
