A slowing down of the jet stream contributed to Harvey’s lingering destruction.

Charles Greene, an atmospheric scientist at Cornell University, believes that warming in the Arctic led to a slowing down of a high-altitude, circulating wind known as the jet stream, which he argues contributed to Harvey’s lingering destruction. 

If that turns out to be the case, it portends more such events to come. 

He suspects recent droughts in the western United States may have been exacerbated by the same phenomenon, as a more sluggish jet stream allowed masses of dry air to get locked into place.
