The ice will survive if temperatures are soon brought back down – new study.
The 10km wide Petermann Fjord in northern Greenland. The author’s icebreaker ship is a small dot in the middle. The cliffs on either side are a kilometre high. In the distance is the ‘ice tongue’ of the glacier flowing into the fjord.

The soil was extracted during the Cold War from beneath one of the U.S military’s most unusual bases, then forgotten for decades.

Glaciologists are discovering new ways surface meltwater alters the internal structure of ice sheets, and raising an alarm that sea level rise could be much more abrupt than current models forecast.

To fully understand the extent of climate-related dangers the Arctic – and our planet – is facing, we must focus on organisms too small to be seen with the naked eye.

A recent paper suggested damaging climate tipping points could be closer than first thought.
A turbulent melt-river pours a million tons of water a day into a moulin, where it flows down through the ice to ultimately reach the ocean.

Climate change is making ocean levels rise in two ways. It’s a problem that will endure even after the world stabilizes and slashes greenhouse gas pollution.
If the world is to adapt to sea level rise with minimal cost, we must address the uncertainty surrounding Antarctica’s melting ice sheet. This requires significant investment in scientific capacity.
When Antarctica’s land-based ice melts, the land bounces up slightly as the weight of the ice lifts. This affects sea levels across the world, but not enough to offset sea-level rise.
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.
