Climate variability

New study challenges long-held theories of climate variability in the North Atlantic

This figure shows the characteristic “horseshoe” model of Atlantic climate variability (upper left panel), as well as the temporal history of this model (lower left). Most of the previous studies attribute this to changes in ocean circulation. Our study compares climate models that include ocean circulation (top right) with climate models that do not have […]

Most people have a fairly clear position on human-induced climate change, even though the vast majority of people don’t know much about the scientific basis of the climate models used to study it. It’s understandable – they are indeed very complicated and not accessible to everyone. In a sense, it doesn’t matter if climate models […]
