Natural and recent atmospheric temperature variations

The average low atmosphere Earth temperature, experienced during the past 4000 years, natural variations of much larger amplitudes than the 20th century variations recorded as around 0.7 ° C .See the here under graph.

There is no reason that the natural causes of these over than 3°C past variations are not still active today and will not be active tomorrow!

• This means  that the Earth average temperature continues to fluctuate, as always.

• The South Pole average temperature recorded by the VOSTOK station is constant since 1958! ( here under )
  
• The Earth low atmosphere average temperature is declining since year 2001, so that CO2 concentration is encreasing as the green curve in the here under graph!
  

What is the relationship between CO2 change during the last 1000 years and the Earth changes in average temperature?
The answer is here below :

During these 1000 years there is no corelation between temperature variation on Earth (recorded in Greenland) and the atmospheric CO2 changes.

Why this should happen today? WHO can explain this (scientifically)?

CONCLUSION:

There is no new thermal disaster on Earth!

At least since the year 1000, the temperature has never been impacted by the atmospheric CO2 gaz variation.

And the current trend is not for temperature rising...
