The extreme weather conditions around the world are interconnected and insidiously self-accelerating, Professor Flannigan explained. The Arctic is warming four times faster than the rest of the world, altering the fast-flowing air currents high above the planet known as jet streams, which then cause wild fluctuations of temperature and precipitation.
