"REYKJAVIK, Iceland — As rising global temperatures speed up the melting of sea ice in the Arctic Ocean, it’s set off a boom of ships taking routes that previously were frozen and not traversable.

The increase in marine Arctic traffic, which received increased attention as U.S. President Donald Trump pushed for the United States to take over Greenland, has come with a heavy environmental cost: black carbon, or soot, that spews from ships and makes the ice melt even faster. Several countries are making a case for ships in the Arctic to use cleaner fuels that cause less pollution in meetings this week with international shipping regulators.

Glaciers, snow and ice covered in the soot emitted by ships have less ability to reflect the sun. Instead, the sun’s heat is absorbed, helping to make the Arctic the fastest warming place on Earth. In turn, melting Arctic sea ice can affect weather patterns around the world."
