Here is more about how raw temperature data was "massaged" to support the AGW hypothesis. Michael Crichton pointed out some years ago that most of the raw data that could be found did not support the AGW hypothesis. The anecdotes about warming were sometimes hilarious. For example I read that pine beetles in the south of the US were more active because of global warming. But even the warmists data indicated that the south of the US had actually cooled in the latter half of the 20th century. So, my question was, how was the existence of global warming communicated to the pine beetles?
