Our new research shows the island's largest glaciers are losing ice faster than previously thought.
Ice floes in the Laptev Sea, Russia.
The Laptev Sea is one of the Arctic's biggest nurseries of new sea ice in winter, but Siberia's record summer heat may have halted production.

Studies show that the Arctic is heating up twice as fast as the rest of the planet.
A small boat in the Illulissat Icefjord is dwarfed by the icebergs that have calved from the floating tongue of Greenland’s largest glacier, Jacobshavn Isbrae.
Sea levels could rise by two metres by 2100, sparking a refugee crisis unlike anything the world has ever seen.

The ice sheet is melting and permafrost is thawing. What's happening in Greenland will speed up climate change across the world.
Water mass enters the ocean from glaciers such as this along the Greenland coast.
Greenland's ice is largely responsible for the accelerating pace of sea-level rise. A new analysis shows that, while Greenland accounted for just 5% of the rise in 1993, that figure rose to 25% by 2014.
The crew of scientists prepare to put the drill stem into the Greenland ice sheet to probe water flows about a half of a mile below.
A glaciologist develops a lightweight method for probing the depths of Greenland's ice sheet to answer a crucial question: How fast is it melting?
