Researchers identify major ecological turnover occurred already before the largest warming event of the past 90 million years

Climate change poses a major threat to the organisms such as plankton that form the base of the marine food web. A team of scientists from MARUM – Center for Marine Environmental Sciences at the University of Bremen have used the fossil record to show that only a relatively minor amount of climatic change is needed to affect plankton communities. They have published their findings in Communications Earth & Environment.
