The clipping below is from a Daily Astorian article on an EPA report regarding global warming’s potential influence on Northwest salmon. Of most import for killer whale conservationists are the implications of what James Martin calls a “perfect storm” for salmon: low snow pack with low, warm flows in the summer.
Martin provides a nice quote regarding the economic impact of such a storm:
“In Oregon, Washington and Idaho, it’s a 35,000-job industry, and it’s worth $3 billion dollars per year,” he said. “So it’s a lot more than just a hobby. There’s a lot at stake.”
That’s about 30x the $100M estimate of ecotourism value associated with the southern residents.
The article also mentions a report co-authored by Martin and Patty Glick called A Great Wave Rising. Dan Drais of Save Our Wild Salmon recently handed me a copy and it looks like an admirable, balanced attempt to bring climate science into the on-going struggle to devise a legal federal plan for recovering endangered fish in the Columbia/Snake basin. I particularly like that it is rich in reputable citations with which I (and global warming skeptics) can understand the uncertainties in the trends and projections.
A quote from Glick suggests that “Heat” should be added to the 4 H’s that govern northwest salmon abundance: harvest, hatcheries, hydropower, and habitat. But just last night, David Montogomery claimed the 5th H should be “History” — the history of salmon-human interactions, particularly in Britain and in the Northeast U.S. So, for me “Heat” has become the 6th H and I’m even more convinced that salmon recovery (linked with killer whale recovery) is one of the most complex, grand environmental challenges of our time.
