(Thread) A scientist’s view of the urgent need for @GavinNewsom to sign SB#1, written by @sentoniatkins.

Like every scientist concerned with preventing #extinction of #SFBay’s fish species, I want #endangeredspecies management to use only the best available science. 1/
@GavinNewsom @SenToniAtkins I supported then-Secretary @sallyjewell's call to review #endangeredspeciesact safeguards for the Bay’s imperiled fish species. Those reviews were necessary bc endangered fish continued to decline; Jewell wrote that she expected the review to lead to increased protections. 2/
@GavinNewsom @SenToniAtkins @sallyjewell Then science-denialists in the Trump Administration manipulated the scientific process used to develop @NOAAFisheries scientific review and tried to bury the best available science. latimes.com/environment/st…
@GavinNewsom @SenToniAtkins @sallyjewell @NOAAFisheries Trump also proposed radical changes in the way the #EndangeredSpeciesAct works that would weaken protections for species & diminish the role of #science in protecting endangered species.
@GavinNewsom @SenToniAtkins @sallyjewell @NOAAFisheries This is exactly why we need #SB1 to ensure that the best available science is the only basis for determining if & how species need to be protected. We can no longer trust the feds to protect #SFBay, #salmon, #steelhead, #sturgeon, or #smelt from unsustainable water diversions.
@GavinNewsom @SenToniAtkins @sallyjewell @NOAAFisheries @USFWS must use the best available science. For example, the feds should immediately list Longfin Smelt as endangered – their review in 2009 found listing warranted scientifically, but action was "precluded" for bureaucratic reasons.
@GavinNewsom @SenToniAtkins @sallyjewell @NOAAFisheries @USFWS And, @CDFW must use the best available science when it writes #CESA permits & listing decisions under #SB1. For ex:
which finds that #ChinookSalmon eggs need colder water below Central Valley Dams than has been required (but rarely provided) in the past.
@GavinNewsom @SenToniAtkins @sallyjewell @NOAAFisheries @USFWS @cdfw @CDFW will also need to use new science that illustrates the effect of freshwater flow rates in our rivers and Delta on the success of Chinook #Salmon, such as:
@GavinNewsom @SenToniAtkins @sallyjewell @NOAAFisheries @USFWS @cdfw And @CDFW must review:
both of which confirm that entrainment of Delta Smelt into the State and Federal water export pumps can have serious negative effects on that species.
@GavinNewsom @SenToniAtkins @sallyjewell @NOAAFisheries @USFWS @cdfw No time for a full lit. review now. But, yes, protection of #endangeredspecies should employ the best available science. Unfortunately, the feds no longer believe in #science. So, if @GavinNewsom wants to defend CA from science-denialism, signing #SB1 is a necessary 1st step.
