Why Greenland? Remote but resource-rich island occupies a key position in a warming world

Greenland plays an outsized role in the daily weather experienced by billions of people and in the climate changes taking shape all over the planet. Experts say the remote, icy and mostly pristine island is where worsening climate change, scarce resources, tense geopolitics and new trade patterns all intersect. Since his first term in office, President-elect Donald Trump has expressed interest in acquiring Greenland, which is an semiautonomous territory of Denmark, a longtime U.S. ally and a founding member of NATO. It is also home to a large U.S. military base.
