Snow surveys taking place across the American west this week are offering a grim prognosis, after a historically warm winter and searing March temperatures left the critical snowpack at record-low levels across the region.
Experts warned that even as the heat begins to subside, the stunning pace of melt-off over the past month has left key basins in uncharted territory for the dry seasons ahead. Though there’s still potential for more snow in the forecast, experts said it will probably be too little too late.
“This year is on a whole other level,” said Dr Russ Schumacher, a Colorado State University climatologist, speaking about the intense heat that began rapidly melting the already sparse snowpack in March. “Seeing this year so far below any of the other years we have data for is very concerning.”
Acting as a water savings account of sorts, snowpacks are essential to water supply. Measurements taken across the west during the week of 1 April are viewed as important indicators of the peak amounts of water that might melt into reservoirs, rivers and streams and across thirsty landscapes through the summer.
In the middle of the 7th century, a plague swept through the walled city of Jerash, in what is now modern-day Jordan.
On February 26, 2025, a NASA probe called Lunar Trailblazer lifted off from Kennedy Space Center in Florida. Its mission was to map the water on the moon. But a day after launch, mission managers lost contact with the spacecraft, and it was never heard from again.
A newly discovered species of large dinosaur lived in marshy areas, hunted for fish and had an impressive horn protruding from its skull. It is the first time in over 100 years that scientists have discovered a new species of Spinosaurus dinosaurs, which are large fish-eating predators that first emerged during the Jurassic period more than 140 million years ago.
