Caught this article in my newspaper today.

Wrote the author of the article this letter:

As far as I can see from the information given, this is somewhat overblown.

There is no obvious "trend" in the chart showing levels of mixing. Many years were as low or lower than the number for 2006. If the study had been done in 2000, what would the "trend" on that chart have looked like? Even the trend in temperature is erratic, and minimal at best. "Extensive computer modeling?" What about the actual record?

The clarity issue is real, and it isn't about global warming, it's about shoreline development and run-off problems that have been there for a long time. By blaming global warming for Tahoe's problems, it becomes a bit too easy for local analysts to say it's all about outside forces instead of the situations in their own back yard that really are causing trouble.
