Climate change exacerbates global water insecurity because it contributes to more frequent and severe droughts, floods and extreme rainfall, accelerated glacier melt, rapid declines in groundwater and the deterioration of water quality.
The effects of climate change are expected to push more than 200 million people from their homes by 2050, according to the World Bank. The impacts are already being felt in the southern U.S. state of Louisiana, where four major weather disasters struck in a nine month period.
