Extreme climate events endanger groundwater quality and stability, when rain water evades natural purification processes in the soil. This was demonstrated in long-term groundwater analyses using new analytical methods.
More frequent strong storms are destroying ever larger areas of the Amazon rainforest. Storm damage was mapped between 1985 and 2020. The total area of affected forests roughly quadrupled in the period studied.
