New footage and photography compiled by a team of scientists at the University of Iceland shows three decades of glacial melt in just over three minutes. CNN reports that the team superimposes archival aerial photos on top of contemporary drone footage to show the dramatic effect that warming climates have had on glaciers in Southeast Iceland. Some of these glaciers are retreating at a rate of 150 metres [492 ft] a year. Since 2000, it’s estimated that Iceland’s glaciers have decreased by some 800 km2 [309 mi2].
The team is led by Þorvarður (Thorri) Árnason, director at the Hornafjörður Research Centre. “About 14 years ago, I started to do repeat photography at one of the glaciers here, Hoffellsjökull,” Þorvarður told CNN. “I went once a month for eight years. It’s like visiting an old friend, there’s a sense of familiarity.”
Iceland has twenty outlet glaciers that extend from the Vatnajökull ice cap. All of them, Þorvarður says, have receded in the time he has been observing them. Some experts say that if global warming conditions continue apace, Iceland’s glaciers are at risk of disappearing completely.
“We need to tell people what the reality is,” says Þorvarður. “On the other hand, we don’t want to frighten people, to immobilize them through anxiety.”
Having documented the present situation, Þorvarður and his team are now turning their attention toward the future. “We want to pre-visualize what our fastest retreating glacier, Breiðamerkurjökull, will look like 100 years from now. Based on worse-case, business as usual, and best case. There is always a range of potential futures that is open to us. There is still a chance for the wounds to heal and for the glaciers to recover, at least to some extent. We have to make a conscious, informed decision about which future we choose.”
