Speedier sea ice in warming Arctic could spread pollution farther

In the Arctic, bad news for one country could mean bad news for all. As the region warms faster than the rest of the planet, new research demonstrates how pollution — from oil spills to organic contaminants — could be passed from one Arctic neighbor to another.
In a new study released in the journal Earth's Future, scientists from Columbia and McGill universities examined the movement of sea ice from country to country in the Arctic Ocean. Comparing data from 1988 to 2014, they found that sea ice is moving faster between destinations, increasing the number of international ice-based exchanges.
