The issue is how the data is being interpreted.
Most people don't realize that the date released to the public is NOT raw data but interpreted data.
That is not a conspiracy or a manipulation because ALL data must be interpreted.
The issue seems to be, for some, HOW it is being interpreted since a minor change in the algorithm gets one OUT of a warning period and into a cooling one and a different change gets you into a warming one in which CO2 FOLLOWS the warning as opposed to preceding it.
