"We, in 150 years, have completely reversed everything the ‘rock thermostat’ has done in the last 3 million years," explained Julie Brigham-Grette. "The transition from a warm Arctic to a cold one that has ice sheets took a million years. We’re jumping out of that in less than 150 years."

‘Never Supposed to Happen’: North and South Poles See Unprecedented Heat

Dr. Julie Brigham-Grette, professor at the University of Massachusetts Amherst department of geosciences and past chair of the Polar Research Board of the US National Academy of Sciences attributed the warming to the movement of the jet streams: a meandering air current that flows from west to east across the globe. Climate scientists have long posited that a changing climate is making the jet streams “wavier,” bring cold currents southward and warm currents northward. That’s what happened over the weekend, Brigham-Grette said.

Antarctica is headed for a climate tipping point by 2060, with catastrophic melting if carbon emissions aren’t cut quickly

The Conversation

Julie Brigham-Grette and Andrea Dutton

2021-05-17

Julie Brigham-Grette writes: "New research shows it is Antarctica that may force a reckoning between the choices countries make today about greenhouse gas emissions and the future survival of their coastlines and coastal cities, from New York to Shanghai."
