As climate stirs Arctic sea ice faster, pollution tags along

A warming climate is not just melting the Arctic’s sea ice; it is stirring the remaining ice faster, increasing the odds that ice-rafted pollution will foul a neighboring country’s waters, says a new study. The new study, which maps the movement of sea ice in the region, underscores the risk of contaminated sea ice drifting from the economic zone of one country to another’s.

Extraordinary storms caused massive Antarctic sea ice loss in 2016

Antarctic sea ice – frozen ocean water that rings the southernmost continent – has grown over the past few decades but declined sharply in late 2016. By March of 2017 – the end of the Southern Hemisphere’s summer – Antarctic sea ice had reached its lowest area since records began in 1978. Puzzled scientists wanted to know why.
