The Nobel prize winning New Zealand scientist, Salinger, was sacked for a reason and that reason was a failure to provide the real data behind the obviously manipulated upwards data used to support climate warming arguments.
The real data shows no warming in NZ but in fact remarkably consistent temperatures for 150 years.
Of course when he got sacked they did not blatantly state this reason.
A question that should be asked is why is all of the manipulated data done so in one direction only?
