In what may be a portent of more to come, a new island has recently emerged from a glacier in Greenland. Geographic researchers using images captured from 2010 to 2019 by the Landsat-8 satellite, to map islands emerging from glaciers in eastern Greenland. These are the latest examples of glacCheck Spellingial retreat creating new islands.

According to the American Geophysical Union (the AGU), Hutchinson Glacier connects to several other islands along its calving front. This Summer, the Glacier lost its ice tongue originally connected to Cape Deichmann, creating Dichmann Island. The ice front is now more than a quarter mile away from the glacier. Several other rocky outcroppings remain with tenuous connections to both the Hutchinson and Polaric Glaciers indicating more new islands will soon form.

Greenland experienced a heatwave during July resulting in billions of tons of meltwater pouring into the north Atlantic Ocean. Temperature anomalies have accelerated the process of island formation along with the ice loss. Climate change is creating the New North.
