This image was taken during the Arctic Ocean 2016(AO16) expedition that ventured to the central regions of the Arctic Ocean, including the North Pole. It shows a pressure ridge, or ice ridge, as viewed from onboard the deck of the icebreaker Oden. It was quite striking that the ice ridge resembled an image of a spine – sea ice being a defining characteristic of the broader Arctic environment and b ...[Read More]

The effects of climate change are being felt all over the world but towns and cities are feeling most hot-under-the collar, a new study finds.

Looking at today’s featured image, you’d be forgiven for thinking the Morenas Coloradas rock glacier wasn’t a glacier at all. But appearances can be misleading; as Jan Blöthe (a researcher at the ...[Read More]

The EGU’s General Assemblies have a long tradition of Great Debates – sessions of Union-wide interest which aim to discuss some of the greatest challenges faced by our discipline. Past topics have included exploitation of mineral resources at the sea bed, water security given an ever growing population and climate geoengineering, to name but a few. This year’s meeting saw the first Great Debate a ...[Read More]
