A pictures challenge has highlighted the extent of ice loss from Iceland’s glaciers.

A crew from Scotland and Iceland in contrast pictures taken within the 1980s with present-day drone photos.

They targeted on the south aspect of the Vatnajökull ice cap, which covers about 7,700sq km of land.

Dr Kieran Baxter, from the College of Dundee, mentioned: “We noticed a staggering distinction in a really quick period of time.”

The challenge – which additionally concerned the College of Iceland and the Icelandic Meteorological Workplace – used aerial photographs taken by a survey airplane within the 1980s.

1000’s of photos have been taken, usually of overlapping areas, and the crew then used software program to remodel these right into a hi-res 3D mannequin of the terrain.

Dr Baxter mentioned this meant that pictures trying straight down on to the panorama might then be re-framed to point out the terrain from completely different angles.

He added: “We will then align them with drone pictures that we will take at the moment.”

The crew hopes the comparability photographs will likely be used for public outreach, to point out how quickly Iceland’s glaciers are retreating.

Iceland’s Met Workplace says the nation’s glaciers have retreated by a complete space of about 750sq km since 2000 – and are shedding a mean space of 40 sq km every year.

This summer season, Icelanders gathered to commemorate the lack of Okjökull glacier. It misplaced its glacier standing in 2014, when the ice grew to become too skinny to maneuver.

However the issue of glacier loss brought on by local weather change is a worldwide difficulty. The most recent Intergovernmental Panel on Local weather Change (IPCC) report warned that smaller glaciers in Europe, Africa, the Andes and Indonesia have been projected to lose greater than 80% of their present ice mass by 2100 if carbon emissions remained excessive.

The ensuing rise in sea degree might have large penalties for hundreds of thousands of individuals, the UN panel warned.
