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.

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. 

The Gulfstream makes northern Europe warmer by transporting heat. This is well known. New research shows that the sea surface temperature also affects storm tracks as far away as the Pacific.

A new study provides evidence of substantial variations in past sea ice cover in the Norwegian Sea, instrumental for several abrupt climate changes between 32,000 and 40,000 years ago. 

Climate change could bring about major disruption for the Indus River and for the millions of people who depend on it. Yet why is it still so challenging to forecast the future of the Indus’ water resources? Michel Mesquita, Lu Li and others investigate that in their new book chapter.

Even though weather forecasts have become very good over the last decades, you can sometimes be waiting for snow that never falls. A new study searches for the origins of an erroneous forecast.  

Winter storm tracks near Norway are not always well represented in global climate models. A new study shows that removing known biases from the start can improve  the results. 

Ice from the Eemian, 125,000 years ago, has been found in ice cores from Greenland. But what did the ice sheet look like then? Andreas Plach writes about challenges in modeling past ice sheets.
