Trump’s announced U.S.–Denmark–Greenland security agreement arrives in an Arctic already transformed by climate change. Melting ice opens navigation and resource access that strategists cite as reasons for permanent security footprints—even as thawing permafrost complicates bases, runways, and radar pads.

Climate scientists note the irony: fossil-fueled great-power competition intensifies in a region suffering the sharpest warming. Environmental groups in Greenland have long warned that militarization and mining without local consent risk ecosystems and Inuit livelihoods.

Any “no cost” claim will eventually meet engineering bills for climate-resilient infrastructure.
