I can verify that the data coming out of NASA is indeed selective. I worked for NASA for 12 years and can tell you that the chief scientist I worked under was most frustrated by the fact that the “research” in this area was driven almost entirely by grants which came only for those whose “research” was geared toward proving AGW. The raw data didn’t support it, but that’s where the money was, and still is.
