On 10 June, a snowy-haired American in his 60s addressed the residents of a remote Greenland hamlet. He was there to tell them about a business venture supported by figures linked to Donald Trump. “So,” Robert Price said via an interpreter, “we have a project to drill for oil here.”

The Texas oil company that Price represents, Greenland Energy, hopes to prove that billions of barrels of crude lie underground by bringing in 300 shipping containers of drilling kit.
