re: NOAA Whistleblower: How world leaders were duped over manipulated AGW data

This is not surprising. Similar manipulations of the historical land based measurements made a small splash a few years ago, will see if I can find an article. Essentially the NOAA released a revised data set that showed much more warming than the last revised data set they had released. The explanation was normalization of the historical data, which is them going in manually changing the values to account for things like changes in equipment at weather stations. This is fine and valid, but it's supposed to be done if there is a clear reason to change the data, like a clear jump or drop in the readings at the point of the equipment change, or notes from the weather observatory that the readings were off due to poor placement of the sensors, etc.. But analysis of the changes to the record showed that nearly all the adjustments to the temperature readings in the early century were revised down, and nearly all the recent adjustments were up. Which took a graph of the raw data from nearly a flat line to a steep rise. There was no rigorous process for making the adjustments, apparently it was done on the whim of whoever was working that day
