The meltdown extends beyond the Arctic. Antarctica recently flirted with a record low in its own annual sea ice minimum – this while the Arctic hits an unprecedented winter low. As a result, Meier notes that global sea ice coverage in February dropped to a record minimum, signifying a broader, planet-wide shift.

Just 5.53 million square miles of ice had formed as of March 22, the smallest maximum extent since satellite recordkeeping began in the 1970s.

Arctic sea ice had its weakest winter buildup since record-keeping began 47 years ago, a symptom of climate change that will have repercussions globally, scientists said Thursday. The Arctic reaches its maximum sea ice in March each year and then starts a six-month melt season.
