KJ: Your points are well taken. I have worked with, and around, university scientists for many years in my "real" job.

That said, there is a huge preponderance of scientific opinion that global warming is a fact. This comes from so many counties and such a huge majority of researchers around the world that I do not think we can ignore them. I would be much more skeptical of the few who are out of step, especially if as some assert they are funded by oil companies.

The vast majority of U.S. climate scientists are funded by various federal grant programs, which does not assure a complete lack of bias, but would seem to make them less biased than those funded by an industry group.

Add to the broad scientific consensus the things we can see for ourselves like the rapidly receding glaciers and the melting of polar ice, and I can only conclude that we are in a rapid warming phase.

I believe that for now I need not try to answer the why question which is hugely divisive but should focus on the what ifs that may come to our salmon if the trend continues.
