In 2019, then-President Donald Trump suggested the United States “buy Greenland” — as a matter of national security. Now in office again, Trump has continued to push for acquisition of the island, illustrated by a recent “horrendous” call with Denmark’s prime minister just last week on the matter.

But it’s not all upside: Even while the effects of a warming planet open up new revenue streams for Greenland’s 57,000-strong population via mining, shipping and tourism, they’ll also have to reckon with potential losses of heritage and new weather risks.
