How NASA is Fudging Climate Data

Warren Meyer of CoyoteBlog and Climate Skeptic has the must-read of the day. It starts:

Let’s say you had two compasses to help you find north, but the compasses are reading incorrectly. After some investigation, you find that one of the compasses is located next to a strong magnet, which you have good reason to believe is strongly biasing that compass’s readings. In response, would you
1. Average the results of the two compasses and use this mean to guide you, or
2. Ignore the output of the poorly sited compass and rely solely on the other unbiased compass?

Most of us would quite rationally choose #2. However, Steve McIntyre shows us a situation involving two temperature stations in the USHCN network in which government researchers apparently have gone with solution #1.

As the man says, click over and read the whole thing.
