Global warming: Want to see Northwest impacts? Just look around

Excerpts:

Global warming is shrinking the winter snowpack. A smaller snowpack means reduction in the runoff that sustains our river flows, makes the desert bloom, allows salmon to reach and return from the ocean, and powers the world's greatest hydroelectric system.

The consequences don't end when our rivers reach salt water. "Climate change and ocean acidification are already having major impacts on Washington: Our $100 million shellfish industry is in crisis after four years of oyster reproductive failure from ocean acidification," said Sen. Maria Cantwell, D-Wash.
