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.

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.

A new study tests various ice sheet modeling setups and shows that changing the surface mass balance has the strongest influence on the ice volume of the Greenland ice sheet on a millennial time scale.

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.

Midlatitude cyclones are often associated with moist processes related to clouds, ocean, and rain. A new study addresses how evaporation of rain contributes to the development of such cyclones.

Could DNA in ocean sediments tell of ancient ice? The first article with such data has just been published, going back 100,000 years. This is Stijn De Schepper's own account.
