The changing of past recorded data is obvious and blatant.
They are cheating and it is obvious why – their science does not stack up!
The current chill in the tropics will need a big reduction in number of temperature measuring sites in that area, to keep their charade “alive”.
In any case, what does it matter? The political attack on our industrialized countries will not cease, because it is already independent from any climate science, valid or not.
Actual global temperature, regardless of measurement accuracy and dishonest data processing, is substantially independent from CO2 levels.
Carbon controls will therefore not affect global temperatures in any significant way.
The UN driven agenda will be maintained no matter how much valid science is ‘thrown into the ring’, unfortunately.
