One of the spurious trends I've noticed is the practice of climate scientists to cherry-pick data. It's pretty obvious that Peterson choose a very peculiar selection of cities for his heat-island study.
I'll wait for an audit of Magnuson's choice of lakes and rivers before I'll buy it as real.
In the interests of your health, I advise you not to hold your breath. Realize that the 2000 study was supported by the 2005 Great Lakes study, both of which I've cited to you. And Magnuson's data is all online. Let McIntyre edit all he wants. It may interest to you to know that the general process of scientific peer-review actually discovered a small error that reduced the reported trends by about a day. I'll leave it to you as an exercise to find out what the error was.
