In 2018, around 16 million people were displaced by extreme climate events. People from poorer countries flee more often as a result of climate events. Scientists at the Max Planck Institutes for Evolutionary Biology in Plön and Meteorology in Hamburg have used a climate game to investigate how extreme climate events combined with poverty affect the migration of people to rich countries if the participants are also expected to finance measures against climate change. In this economic experiment, the representatives of the wealthy countries were rarely able to stop climate change and migration. In contrast, the representatives of the poorer countries are prepared to support a minimum level of climate protection by the rich.
