The geopolitical and environmental significance of Greenland's warming climate

This event isn't on the map, but everything else — summary, consequences, sources — is unaffected.
Warming at four times the global average, Greenland experienced significant environmental shifts that threatened the viability of remote settlements like Sarfannguit, where residents faced unpredictable sea ice and shifting fish stocks. Geopolitical experts, including Professor Klaus Dodds, identified the melting of the island’s ice sheet—which covers over 80 percent of its land—as a major contributor to global sea-level rise. Research by Benjamin Horton and the IPCC indicated that this melting posed direct risks to coastal populations and infrastructure across Asia, particularly within river deltas and low-lying cities such as Jakarta and Manila.
Consequences
Under the IPCC's highest emissions scenario, Greenland's ice sheet was projected to contribute between 9cm and 18cm to global sea-level rise by 2100. This shift threatened to impact the waterfronts, transport systems, and water supplies of the approximately 70 percent of the global population exposed to sea-level rise who reside in eight specific regions, many of which are in Asia.
