The National Snow and Ice Data Center reported Wednesday Arctic Ocean sea ice grew last winter to the lowest maximum extent ever recorded, in another sign that human-driven global warming is irrevocably changing the planet. The record low extent of the ice followed a number of record high temperatures in the Arctic over the winter, with measurements at the North Pole repeatedly climbing by as much as 50 degrees Fahrenheit above normal.
