Massive Temperature Adjustments In Brazil – And Guess In What Direction?

Who needs natural cycles interfering with the nice linear graphs climate scientists seem to so prefer?

NOT A LOT OF PEOPLE KNOW THAT

A quick update to my post on Brazilian temperature trends.

Ian George spotted that the original trends, based on unadjusted GHCN V2 data, for Quixeramobim, up to 2011, looked like this:

The current GISS graph, based on GHCN V3 Adjusted data, is:

The adjustments that GHCN have made are massive, and have turned a cooling trend into a rapidly warming one.

Was there anything wrong with the original record? I don’t know, but anybody who claims that they can accurately measure what the temperatures really were is a fraud.
