UN warns of impending global water crisis due to overconsumption and climate change.

The UN World Water Development Report warns of a looming global water crisis due to increased demand and the intensifying impacts of the climate crisis. By 2050, the number of people in cities facing water scarcity is projected to nearly double from 930 million people in 2016 to up to 2.4 billion. Without action, there will be a global crisis, says the report's lead author. Solutions include better international cooperation to avoid conflicts over water, flood and pollution control, data sharing, and efforts to reduce levels of planet-heating pollution.
