Chinook salmon swim in warming rivers

Warming temperatures threaten an entire run of Chinook salmon, which California officials blame on drought, climate change and a Trump-era water policy. SACRAMENTO, Calif. (CN) — Facing another summer of catastrophic fish kills, California lawmakers and fisheries managers on Tuesday blamed a Trump-era water policy and climate change for the sizzling water temperatures threatening to erase an entire run of Chinook salmon. “We’re witnessing the collapse of this iconic species right in front of our eyes,” said state Senator Mike McGuire, a Democrat from Santa Rosa.

By: SN&R Staff August 5, 2021 By Dan Bacher In an extreme drought year where nearly all juvenile Sacramento River winter run Chinook salmon are expected to die before spawning due to alleged water mismanagement by the state and federal governments, the return of a record run of adult spring run Chinook salmon on Butte Creek this […]

By The Times Editorial BoardJuly 26, 2021 The news reports about the California salmon wipeout got a good chunk of the story right: Record-breaking heat waves made Northern California rivers too warm to sustain migrating chinook salmon, and virtually all of the salmon in the Sacramento River this summer have died, or will die, before reproducing. Any eggs that were […]

June 28, 2021 Written by Communications Intern Sage Bachman As California enters another severe drought, residents are once again being asked to use water more judiciously so as to make it last longer. While it is indeed crucial for all of us to reduce our water usage, is also critical to investigate how California’s limited sources […]

The highly engineered rivers that sustain California cities and farms upset streamside woodlands’ relationship with groundwater, a new study finds, jeopardizing their future in a changing climate.

California’s perennially drought-parched Central Valley bears little resemblance to the vibrant landscape of the pre-Gold Rush days, when wild rivers sustained lush woodlands and floodplains teeming with life.

Trees at the center of these biodiversity hotspots evolved in an arid landscape sculpted by finely tuned exchanges […]

The two leading science groups studying ecosystems and climate urged protection of carbon-rich habitats and warned against solutions to warming that lower species diversity. By Georgina GustinJune 11, 2021 Slowing global warming and stemming the loss of biodiversity have been viewed as independent challenges for years. But a new landmark report concludes that climate […]

In order to roll back catastrophic carbon emissions, humans must “start developing the technologies for large-scale removal of greenhouse gases from the atmosphere,” … Humanity may have passed the “point of no return” in the climate crisis—even if everyone on the planet stopped emitting all greenhouse gases at this very moment, according to a study published Thursday.

Antarctic research station

Scientists at an Antarctic research station recently recorded a one-day air temperature of just under 70 degrees, a balmy afternoon in a region of the world unaccustomed to them. In fact, as far as researchers can tell, it has never been that warm in Antarctica before. The record was set against an increasingly scary global backdrop of rising temperatures and seas; more powerful storms, droughts and floods; a reduced Arctic ice cap, and accelerated melting and movement of glaciers around the globe — including Antarctica.
