Today we gather scientific information regarding a key subject not just for the Nordic countries, but rather for the whole world: icebergs melting in Greenland. We strongly recommend the readers to visit the original sources fully mentioned below.

An excerpt (summarised with Resoomer) from “Holes And Increased Melting Are Spelling Disaster For Greenland’s Ice” published on IFLSCIENCE.COM

Greenland’s ice sheet and glaciers have an uncertain future. A new study has found that the holes in the ice are larger than previously thought, while separate research suggests the island’s largest glaciers are melting faster than feared. In late-September, a different study showed that Greenland may lose up to 36 trillion tonnes of ice, 12 times the total loss of the last century, depending on how well we curb greenhouse gas emissions. If that were to happen, it would add 9.9 centimeters to the global waterline. To begin the study, later published in Geophysical Research Letters, it was crucial to establish how big these holes actually were inside the sheet: the team found they are much larger than they appear from the surface and in models.

An excerpt (summarised with Resoomer) from “Greenland’s Three Largest Glaciers Retreating Ice Faster than Expected: Study” published on WEATHER.COM

The three largest glaciers of Greenland are on the verge of collapse as the ice is melting at a faster rate than previously expected, warns new research. Together, the three glaciers hold enough ice to increase the global sea level by at least 1.3 metres if melted. Such an extent of sea-level rise could inundate several major coastal cities like Mumbai and Chennai. For the study, researchers examined the three largest glaciers of Greenland, namely Jakobshavn Isbrae, Kangerlussuaq Glacier and Helheim Glaciers. The team used various sets of data derived from historical photographs, recent satellite images, and aerial stereo-photogrammetric imagery to calculate the ice loss between 1880–2012.

An excerpt from “Greenland is melting: we need to worry about what’s happening on the largest island in the world” published on THECONVERSATION.COM

Greenland is the largest island in the world and on it rests the largest ice mass in the Northern Hemisphere. If all that ice melted, the sea would rise by more than 7 metres. But that’s not going to happen is it? Well not any time soon, but understanding how much of the ice sheet might melt over the coming century is a critical and urgent question that scientists are trying to tackle using sophisticated numerical models of how the ice sheet interacts with the rest of the climate system.
