Bad news on the glacial front. “When the snow leaves the mountains the world ends”-Native legend. Likely true for civiluzation on the peninsula. Our society here depends on it glacial runoff.
Puget Sound’s glaciers are melting rapidly due to climate change. The North Cascades mountains have lost about 56% of their glacial ice while estimates show that glaciers in the Olympics could be gone within the next 50 years. Scientists say salmon and other species could be hard hit as the region loses its “giant storage tank” of ice.

Good news and concerning news from some recent science.
Many salmon rivers around Puget Sound have experienced increasing fluctuations in flow over the past 60 years, just as climate change projections predict – and that’s unfortunate news for threatened Chinook salmon, according to a new analysis of salmon survival and river flow. More pronounced fluctuations in flow can scour away salmon eggs and exhaust young fish, especially when lower flows force adult fish to lay eggs in more exposed areas in the center of the channel. The new study published in the peer-reviewed journal Global Change Biology says such increased flow variability has the most negative effect on salmon populations of several climate factors considered.

Scientists have discovered an overall improvement in the amount of pesticides flowing in Washington State streams….State Agriculture officials said pesticide concentrations declined over the past decade in salmon bearing streams. They also said most were below levels of concern. But they did find 10 of the 74 pesticides they test for were increasing in concentrations.
