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.

The freshening of the western North Atlantic from ice melt started as early as in the 1940's, new study indicates.

Kristian Vasskog's group found marine sediments higher on the island Karmøy than they thought the sea had reached. Southern parts of the island must have escaped the ice age much earlier than areas nearby.

In the last interglacial, the sea level rose to ten meters higher than today. For the first time, researchers have now traced the extra water to Antarctica.

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. 

In the coldest years of the last ice age, the ice cap reached the British Isles and Poland. New research has revealed a green patch much closer to the North Pole. Part of a peninsula in Svalbard was free from ice.

Warm summers have made Siberia greener. A new study shows that higher temperatures do not always equate to greening. Rainfall may be a limiting factor for some forest types. 

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. 

The jet stream influences European weather at all times. A new study links its position both to local weather systems and to the Pacific.
