A 30-minute walk throughout New York’s Central Park separates Trump Tower from the American Museum of Herbal Historical past. If america president ever discovered himself throughout the museum he may see the Cape York meteorite: a 58-tonne mass of iron taken from northwest Greenland and offered in 1897 via the explorer Robert Peary, with the assistance of native Inuit guides.
For hundreds of years earlier than Danish colonisation, the folks of Greenland had used fragments of the meteorite to make gear and looking apparatus. Peary got rid of that useful resource from native keep an eye on, in the long run promoting the meteorite for an quantity identical to only US$1.5 million as of late. It was once a transaction as one-sided as anything else the president might now be considering.
However Donald Trump is now eyeing a prize a lot better than a meteorite. His advocacy of america taking keep an eye on of Greenland, perhaps via power, alerts a shift from dealmaking to dominance. The medical value could be serious. A unilateral US takeover threatens to disrupt the open medical collaboration this is serving to us perceive the specter of world sea-level upward thrust.
Greenland is sovereign in the entirety rather then defence and overseas coverage, however via being a part of the Kingdom of Denmark, it’s integrated inside Nato. As with every country, get entry to to its land and coastal waters is tightly managed via lets in that designate the place paintings might happen and what actions are allowed.

Over many a long time, Greenland has granted global scientists get entry to to lend a hand release the environmental secrets and techniques preserved inside its ice, rocks and seabed. US researchers had been a number of the primary beneficiaries, drilling deep into the ice to give an explanation for the historical hyperlink between carbon dioxide and temperatures, or flying repeated Nasa missions to map the land underneath the ice sheet.
The entire global owes an enormous debt of because of each Greenland and america, very ceaselessly in collaboration with different international locations, for this medical growth performed brazenly and quite. It is very important that such paintings continues.
The local weather science at stake
Analysis displays that round 80% of Greenland is roofed via a colossal ice sheet which, if absolutely melted, would carry sea point globally via about 7 metres (the peak of a two storey area). That ice is melting at an accelerating price as the arena warms, freeing huge quantities of freshwater into the North Atlantic, doubtlessly disrupting the sea flow that moderates the local weather around the northern hemisphere.

The remainder 20% of Greenland continues to be more or less the dimensions of Germany. Geological surveys have printed a wealth of minerals, however economics dictates that those will possibly be used to energy the golf green transition relatively than extend the fossil gasoline generation.
Whilst coal deposits exist, they’re these days too pricey to extract and promote, and no primary oil fields had been found out. As a substitute, the industrial center of attention is on “critical minerals”: high-value fabrics utilized in renewable applied sciences from wind generators to electrical automotive batteries. Greenland due to this fact holds each medical wisdom and fabrics that may lend a hand information us clear of local weather crisis.
Unilateral keep an eye on may threaten local weather science
Trump has proven no interest in local weather motion, on the other hand. Having already began to withdraw america from the Paris local weather settlement for a moment time, he introduced in January 2026 the rustic would additionally depart the Intergovernmental Panel on Local weather Exchange, or IPCC, the worldwide medical frame that assesses the affects of endured fossil-fuel burning. His rhetoric up to now has been about obtaining Greenland for “security” functions, with some indications of gaining access to its mineral wealth, however with out point out of essential local weather analysis.

Underneath the 1951 Greenland defence settlement with Denmark, america already has a far off army base at Pituffik in northern Greenland, now serious about house actions. Whilst each nations stay in Nato, the settlement already permits america to amplify its army presence if required. Looking for to ensure US safety in Greenland outdoor Nato would undermine the prevailing pact, whilst a unilateral takeover would chance scientists in the remainder of the arena dropping get entry to to some of the essential local weather analysis websites.
Courses from Antarctica and Svalbard
Greenland’s sovereign standing and its governance is other to a couple different notable polar analysis places. For instance, Antarctica has, for greater than 60 years, been ruled via a world treaty making sure the continent stays a spot of peace and science, and protective it from mining and different environmental harm.
Svalbard, alternatively, has Norwegian sovereignty courtesy of the 1920 Svalbard treaty however operates a in large part visa-free machine that permits electorate of just about 50 nations to are living and paintings at the archipelago, so long as they abide via Norwegian legislation. Apparently, Norway claims that medical actions don’t seem to be lined via the treaty, to nearly common confrontation amongst different events. Russia has an enduring station at Barentsburg, Svalbard’s second-largest agreement, from which small ranges of coal are mined.
In contrast to Antarctica or Svalbard, Greenland has no treaty that explicitly protects get entry to for global scientists. Its openness to analyze due to this fact relies now not on global legislation, however on Greenland’s endured political balance and openness – all of that may be threatened via US keep an eye on.
Whether it is minded to take a thorough method, Greenland may increase its personal treaty-style method with decided on spouse states via Nato, enabling safety cooperation, mineral evaluate and medical analysis to be performed collaboratively beneath Greenlandic rules.
The longer term for Greenland must lie with Greenlanders and with Denmark. The way forward for local weather science, and the transition to a protected wealthy long term international, will depend on endured get entry to to the island on phrases set via the folks that are living there. The Cape York meteorite – taken from a web site simply 60 miles clear of america Pituffik House Base – is a reminder of the way simply that keep an eye on will also be misplaced.
