Nearly 80 people have been rescued, and two people confirmed dead, after flood hit national park

A US border patrol technical search team is expected to deploy in the Grand Canyon, as authorities continue the search for at least one missing person after a fatal flash flood washed through the national park over the weekend.

Authorities are rushing to scour the area as more heavy rain and thunderstorms in weather forecasts threaten additional debris flows, flash floods or rock falls.

The deluge capped a summer of extreme climate events, from deadly heatwaves to wildfires. We must take action now

For millennia, the high peaks of the Himalayas were held together by an invisible, frozen cement – permafrost and glacial ice that bound ancient rock into seemingly unshakable fortresses. But as the planet continues to warm, this alpine glue is liquefying.

The glacial collapse and deluge in Nepal and Tibet was not a freak weather event; it was the structural failure of a mountain itself, nature’s latest commentary on the deadly consequences of human-caused planetary warming. And it was the exclamation point on a summer of extremes, illustrating with a sole unnatural disaster the apocalyptic future that lies in store if we fail to take dramatic climate action.
