Scientists just found a surprising possible consequence from a very small amount of global warming

Even if we meet our most ambitious climate goal — keeping global temperatures within a strict 1.5 degrees Celsius (or 2.7 degree Fahrenheit) of their preindustrial levels — there will still be consequences, scientists say. And they’ll last for years after we stop emitting carbon dioxide into the atmosphere. New research suggests that extreme El Niño events — which can cause intense rainfall, flooding and other severe weather events in certain parts of the world — will occur more and more often as long as humans continue producing greenhouse gas emissions.
