To narrow our predictions of global sea level rise, we need to know more about these sudden ‘non-linear’ changes to ice sheets.

Scientists now have a better understanding of the risks ahead and a new early warning signal to watch for.

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.

Some of the world’s biggest glaciers flow into fjords in Greenland and we need to know what they’ll bump into on the seabed.

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.

Seafloor landforms reveal that ice sheets can collapse at 600 metres per day.

The annual report is also a reminder that what happens in the Arctic affects the rest of the world.
Tipping points in the climate become more likely beyond 1.5°C of warming.

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.

Between zero and 2,000 icebergs reach Newfoundland each spring, but the warming climate could see an end to Iceberg Alley.

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.

Glaciers aren’t sterile wastelands – they’re chock-full of microscopic life.

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.

Our new research shows the island’s largest glaciers are losing ice faster than previously thought.

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.

Sea levels could rise by two metres by 2100, sparking a refugee crisis unlike anything the world has ever seen.
