"Imagine turning into a liquid on a hot summer day", writes Willem Van der Bilt. To avoid that, some algae change their body fat. Fat in fossile algae reveal that Svalbard was seven degrees warmer 10,000 years ago.

Perhaps nowhere is the difference between cities and their surroundings greater than in the Arctic. Igor Ezau writes about a new study attempting to connect the environmental impact of Arctic cities with socio-economical decisions and policy governing city growth and decay.

Changing winds influence the heat exchange between the atmosphere and the ocean. A new study by Fumiaki Ogawa and Thomas Spengler shows how important it is to consider extratropical cyclones and cold air outbreaks when calculating air-sea fluxes.

In a number of European countries, there is a clear imbalance between long-term disaster risk reduction and short-term preparation, new study finds. More data allows for better planning, but is not enough. Jenny Sjåstad Hagen emphasizes the importance of data interoperability. 

With increasing CO2 emissions to the atmosphere, the content of anthropogenic carbon in the oceans also increase. In the Arctic, the strongest increase has occurred in the Nansen sub-basin, a new study shows. 

Around 10,000 years ago, the ice melted away from northern Sweden, ending the ice age in Scandinavia. Ancient shorelines place the last remnants of the ice in the lowlands, not in the mountains.

The cold and warm climatic phases of the past 2000 years were not, as previously assumed, global phenomena. The climate varied greatly from region to region. That’s according to a study by the University of Bern that has just been published in Nature. In contrast to earlier times, current, anthropogenic climate change is occurring across the whole world at the same time.

Climate simulation models include more and more processes – not only physical, but also biogeochemical cycles. Can single individuals keep an overview of the major factors governing climate change? Christoph Heinze has led a study that can help you.

Using statistics of the past to predict the future can fail if associations change. Erik Kolstad writes about his new study of Barents-Kara sea ice and European winter weather.
