The delta smelt is on a trajectory toward extinction in the wild. Heading into 2017, the spawning adult population was at an all-time low, although this past wet winter has apparently seen a small resurgence. However, increasingly warm summer temperatures in the Delta may dampen any upswing. Given the long-term trajectory of the population and climate predictions for California, maintaining delta smelt in the Delta for the next 20–30 years is not likely to happen without significant improvements to the habitat.

You are now in California and the U.S. category.
After suffering more than a week under searing, desert-like heat, winter might be the furthest thing from the minds of Southern Californians. However, to borrow a phrase from TV’s “Game of Thrones,” winter is coming. The only question is whether the gods will allow a rerun of last winter which unexpectedly dumped record amounts of rain and snow throughout the state that filled reservoirs and kept skiers on the slopes through August.
You’ve heard of The Big One. Now meet The Other Big One – a massive statewide flooding catastrophe that could cripple California for months or years. Researchers think a megaflood is just as likely to hit the state as a 7.8 magnitude earthquake, and has the potential to cause three times as much damage. San Diego County alone would suffer $25 billion in losses under a doomsday “atmospheric river” scenario created in 2011 by dozens of researchers during which a series of heavy storms would slam the northern and central parts of the state.
