NOAA has reported that a west coast marine heatwave is forming that rivals “The Blob” heatwave of 2013-2016. The last time this happened anadromous fish returns were significantly depressed. Combined with the drought we are likely to be entering this is not good news for steelhead and salmon returns. “Past marine heatwaves shook up marine ecosystems that drove shifts of species, die-offs, and other disruptions of ecosystems in the Northeast Pacific Ocean.” Global warming marches on.
