Glaciären som utplånats av klimatförändringar hedras

Okjökull är den första av Islands glaciärer som har försvunnit till följd av klimatförändringar. På söndagen ska den hedras på plats vid en ceremoni där statsminister Katrin Jakobsdottir och FN:s kommissionär för mänskliga rättigheter, Mary Robinson, deltar tillsammans med forskare, skriver AFP.

Ett bronsplakat som hedrar den ”döda” glaciären kommer att avtäckas under söndagens ceremoni.

The glaciers and ice caps of Iceland cover 69./. of the land area of the country (about 11,400 km² out of the total area of 103,125 km²) and have a considerable impact on its landscape and meteorology. An ice cap is a mass of glacial ice that covers less than 50,000 km² of land area covering a highland area and they feed outlet glaciers. Glaciers are also contributing to the Icelandic economy, with tourists flocking to the country to see glaciers on snowmobiles and on glacier hiking tours. Many Icelandic ice caps and glaciers lie above volcanoes, such as Grímsvötn and Bárðarbunga, which lie under the largest ice cap, Vatnajökull. The caldera of Grímsvötn is 100 km² in area, and Bárðarbunga is 60 km². When volcanic activity occurs under the glacier, the resulting meltwater can lead to a sudden glacial lake outburst flood, known in Icelandic as jökulhlaup, but jökulhlaups are most often caused by accumulation of meltwater due to geothermal activity underneath the glacier. Such jökulhlaups have occasionally triggered volcanic eruptions through the sudden release of pressure. Iceland is losing ice due to climate change. Okjökull glacier in Borgarfjörður, West Iceland, has lost its glacier title and is now simply known as "Ok", losing the Icelandic word for glacier, jökull, as a suffix. In order to fit the criteria glaciers need to be thick enough to sink and move under their own weight, which Okjökull is not. Okjökull is the first Icelandic glacier to lose its title.
