Do we have the right tools to reach the targets agreed upon in Paris? Do climate models deliver what we need to tackle climate change? These questions were on the agenda for Norwegian climate modelers last week. 

By taking up CO2, the oceans slow down the pace of climate change. But this invaluable service of the oceans comes at a cost. Are Olsen, Nadine Goris, Siv Kari Lauvset and Ingunn Skjelvan are revisiting the problem of ocean acidification in a new Foresight Brief published by the UN Environment. 

Lea Svendsen was at first surprised to see how the Pacific impacted winter temperatures in the Arctic. Now, her results have been published in Nature Climate Change, while the Pacific transitions into a warm phase again. 

The Arctic is about to shrink, shows a new study, as an important part of the Arctic Ocean shifts over to an Atlantic climate regime. The rapid climate shift occurs in the northern Barents Sea—the Arctic warming hotspot where the surface warming and loss of winter sea ice is largest in the entire Arctic. 

What climate research does governments need, and what can scientists offer? ICOS Norway and the Norwegian Environment Agency discussed the issues in a June seminar.

Will European winters be increasingly mild and wet in the coming years? Will climatic conditions be beneficial for Norwegian fisheries and hydroelectric power production? Such questions of large societal importance are at the heart of the emerging scientific field of climate prediction.

On TV weather maps we see low pressure centers as circles resembling tree-rings, with long tails of red warm fronts and blue cold fronts. But what came first – the low or the fronts?
