In case you hadn’t heard, El Niño is back in the news, and this time it’s pushing global temperatures to the 1.5-degree climate threshold, giving us a sneak preview of a world scorched by global warming. But when it comes to El Niño, the first question on people’s minds is usually…wait…what the heck is El Niño again?Well, today on Outside/In we’ve got answers. Plus, we ask how to tell if extreme weather events are caused by climate change or by El Niño, and consider what this El Niño can tell us about our climate future.Featuring Kim Cobb, Emily Becker, and Ángel Muñoz. SUPPORTOutside/In is made possible with listener support.
