In October 2019, the research icebreaker ‘Polarstern’ was moored to an ice floe for its year-long journey through the Arctic Ocean. Come with us on a slightly shorter journey and learn how MOSAiC participants from the supporting cruise educate the future generation of polar scientists! What is the MOSAiC expedition? The MOSAiC (Multidisciplinary drifting Observatory for the Study of Arctic Climate ...[Read More]

We know that climate change is being felt worldwide, but it is especially prominent in the Arctic, where temperatures are warming twice as fast as anywhere else on the planet. This especially sensitive environment, whose icy, snow-covered land and sea is so important in the global climate system, is really starting to feel the heat. But where is this heat coming from? In this blog post, we will ex ...[Read More]

You have probably heard the name “Intergovernmental Panel on Climate Change (IPCC)” mentioned frequently over the last few years. The IPCC is the United Nations body for assessing science related to climate change and it publishes global assessment reports on this topic every 5 to 10 years. Due to the current urgency of the global climate crisis and the need for more information by decision makers ...[Read More]
Climate Change & Cryosphere – Summer 2019: The year that the Arctic was sunburned
June, July and August 2019 saw extensive heat waves across Europe, with air temperatures reaching above 40°C in many countries. In response, record breaking ice melt was observed in Greenland and wildfires in Siberia, Alaska, Arctic Canada and Greenland occurred. A particularly dry and warm summer was responsible for hemisphere-wide changes to the cryosphere. In this week’s post, we will review so ...[Read More]
Climate Change & Cryosphere – Why is the Arctic sea-ice cover retreating?

The Arctic Ocean surface is darkening as its sea-ice cover is shrinking. The exact processes driving the ongoing sea-ice loss are far from being totally understood. In this post, we will investigate the different causes of the recent retreat of the Arctic sea-ice cover, using the most updated literature… Arctic sea ice is disappearing Due to its geographical position centered around the Nort ...[Read More]
