If the ocean circulation, known as AMOC, shuts down, it would be a climate disaster, particularly for Europe and North America. New research shows why that might not happen as soon as some fear.

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.

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.
Rainier winters make life more difficult for Arctic wildlife and the humans who rely on them.

The new discovery echoes a mission in 1931, when a five-day zeppelin flight sent robots to the stratosphere and redrew the maps of the high Arctic.
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.

Polar bears are increasingly seeking sustenance in human trash because of melting sea ice and a loss of hunting opportunities. The result is a rise in human-bear conflict – and dead bears.

Sea ice is thinning at an alarming rate. Snow is shifting to rain. And humans worldwide are increasingly feeling the impact of what happens in the seemingly distant Arctic.
Nearly 60 years after a radiation-leaking reactor was removed from a US Army base on the Greenland ice sheet, the military is exploring portable nuclear reactors again.
