How snow loss is fueling the West’s megadrought

- Lake Mead is America’s largest reservoir, supplying water for 25 million people across the southwest. It’s also drying up - a kind of poster child for the ongoing drought in the West. But upstream, a much larger but lesser known source of stored water is also disappearing: mountain snow.
This is how climate change is throwing one of the United States’ most critical sources of water out of whack.
In the near future, the West could lose about a quarter of its historical snowpack. As for the end of the century, that’s where climate models start to diverge, largely depending on how fast we end up taking action on the climate crisis.

This channel is severely underrated.
Nice job explaining this important issue. It relates to the need to remove the four lower Snake River dams. Scientists think the watersheds in Idaho will have more snow than rain, protecting salmon redds (nests) and helping more fish to hatch and grow.
