Polar Ice Is Disappearing, Setting Off Climate Alarms
Turns out, when you heat up ice, it melts. And with 2017 likely going down as one of the warmest years on record worldwide, this year's climate change signal was amplified at the Earth's poles. There, decades-old predictions of intense warming have been coming true. The ice-covered poles, both north and south, continue to change at a breathtaking pace, with profound long-term consequences, according to the scientists who study them closely. And the consequences are destined to spill over into other parts of the globe, through changing atmospheric patterns, sea currents and feedback loops of ever intensifying melting. The past year may not have broken annual records, but it provided ample evidence of where long-term trends are heading.
