I also saw a look at N American summer temperatures from the 50s to now. Huge increases, like 5 degrees, and more in AK. But if you were born midway in that period, summer isn't much warmer. I suspect that all of us, when we look at impacts, look to estimate returns, and all that only look over our years of actual experience. I would be really surprised if the WDFW folks looking at fish/climate/water/whatever are using the data that goes back in some cases more than 100 years or just looks recently.
