Arctic warming likely turned Harvey into "an extreme killer storm"

"What happens in the Arctic doesn’t stay in the Arctic."

Melting Arctic ice and spiking temperatures don’t just affect the northernmost part of Earth. According to Cornell University professor Charles Greene, they can also impact storms, like Hurricane Harvey, that are thousands of miles away – prompting them to stall or meander. He said in a statement, "What happens in the Arctic doesn’t stay in the Arctic. Just like Superstorm Sandy, Arctic warming likely played an important role in making Hurricane Harvey such an extreme killer storm."
