Storm Dave, which swept across northern Europe over the Easter weekend, is an example of what new research from the University of Gothenburg has revealed. Spring storms forming over the North Atlantic have become more common than they were 80 years ago, and this is due to climate change.

In the Northern Hemisphere, storm seasons follow a seasonal cycle. Storms are weakest and least frequent in summer and most intense in winter. As a result of global warming, storm patterns and their course have changed, and several studies have indicated that winter storms appear to be occurring more frequently and with even greater intensity.
