From UPSC perspective, the following things are important :
Prelims level : Qeqertaq Avannarleq
Mains level : Impact of climate change
A group of researchers who went out to collect samples off the coast of Greenland in July found themselves on a tiny, uninhabited and previously unknown island.
- Measuring 60×30 metres and with a peak of three metres above sea level, it has now become the new northernmost piece of land on Earth.
- Before this, Oodaaq was marked as the Earth’s northernmost terrain.
- The new island is made up of seabed mud and moraine, i.e. soil, rock and other material left behind by moving glaciers, and has no vegetation.
- The group has suggested the discovery be named ‘Qeqertaq Avannarleq’, which is Greenlandic for “the northernmost island”.
How this island came to existence?
Ans. Undoubtedly, climate change in Greenland
- Global warming has had a severe effect on the ice sheet of Greenland.
- The new island, which was exposed by shifting pack ice, is, however, not a direct consequence of climate change.
