Thanks to pollution, overpopulation and the climate crisis, Earth is facing a terrifying new crisis: an irreversible 'water bankruptcy'. Now, fights over water have ramped up across the world, including in the US west. Host Carter Sherman speaks with Guardian extreme weather correspondent Gabrielle Canon about the battle over the future of the Colorado River Basin, whose water sustains some 40 million people across seven states – but is now drying up. Gabrielle recently rafted down the basin's last 'wild' river, the Yampa. Damming or diverting the Yampa could bring the west some much-needed hydration. It may also devastate the vast natural ecosystem that relies on the river's free-flowing waters. Also: Carter and Kai Wright react to the death of South Carolina Senator Lindsey Graham

Shortages triggered by pipeline rupture drive up costs and deepen frustrations, as pressure grows on water utility

Jonathan Collazo owns two restaurants in a bustling section of San Juan, which has been plagued by water outages, severely disrupting the daily lives of residents and businesses alike.

The water scarcity is part of an escalating frustration felt by thousands of customers of Puerto Rico’s water utility over the past several months, prompting the governor to activate the national guard to distribute drinking water across the US territory. The shortages extend beyond San Juan, with sectors in municipalities including Loíza, Guaynabo, Bayamón and others experiencing interrupted service.

As US water wars rage, a tributary of the Colorado River faces unprecedented pressure. Visitors worry how long this aquatic ‘relict’ will last

On an early morning in mid-May, a group of near strangers shoved camping gear and clothes into waterproof bags, slathered on sunscreen, and ambled into the bright-yellow rafts that would carry them down one of the last free-flowing rivers in the American west.

Unhindered by large dams or diversions, the Yampa curves across 250 miles (400km) of alpine tundras, cottonwood forests and ancient red-rock canyons, rising from Colorado’s Rocky mountains to where it joins with the Green River in Utah, much in the way it has for millions of years.

Meta said it was working with officials to be a ‘good neighbor’ and drinking water supplies were not affected

Officials in Wyoming said a contractor for Mark Zuckerberg’s tech company, Meta, flushed bacteria-contaminated water into public sewers during construction of a controversial new AI datacenter.

The incident prompted water authorities in Cheyenne to implement strict safety regulations on how wastewater from such projects is disposed of, according to the Wyoming Tribune Eagle, which first reported the incident.
