MARUM study in Nature: New analysis method shows abrupt increase in seasonality during last global climate change

How is the weather changing as a result of global warming? Climate archives provide valuable insights into past climate changes, i.e. into the processes that transported our planet from one climate state to the next. However, for humans and ecosystems, the variability in time scales of weeks to years – the weather – is often crucial. Using a newly developed and tested analytical method at MARUM – Center for Marine Environmental Sciences at the University of Bremen, these two aspects have now been brought together to describe the effects of recent global warming on seasonal temperature variations. The journal Nature has now published the results.
