Great article Zzedzz! Professor Zbigniew Jaworowski dedicated most of his professional life measuring CO2 and analysing the data, his research was posted on HC before.
To claim lower preindustrial CO2 levels most of the records including 69% of the 19th century records has been rejected and only selected certain records that established the pre-industrial level as 280 ppm !!! How scientific : ))))
So much distortion of historical data, false assumptions, only to achieve the smooth hockey curves in order to create one Hypothesis based on false data and nothing more!
You can also see the temperature curve clearly preceding the CO2 curve.
Everyone concerned about the real scientific side, and not only ideology should be very interested :)
