Global warming increases the risk of more frequent—and heavier—rainfall, snowfall, and other precipitation. And as that risk increases, so too does the risk of flooding.
What will global warming do in 100 years?
If global warming is kept to 2℃, the availability of water is expected to decrease in some areas such as the Mediterranean by up to 50%. Globally, the additional warming could lead to a 20% increase in the number of people affected by chronic water scarcity. Sea level is expected to rise for centuries.
