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. 

During the last interglacial, there were large variations in the circulation in the South Atlantic, both at the surface and at depth. The overturning circulation in the Atlantic was still maintained.
