Vostok Ice Cores Show Zero Climate Sensitivity (Temperature is not affected by CO2)

Vostok is a Russian base in the centre of the Antarctic -- so ice cores from there should be least affected by external influences. Warmists make a lot of use of ice-cores in their fairy tales but ignore any history that does not suit them, of course

Vostok ice core data

Over the last sixty years, atmospheric CO2 has risen almost 50% higher than at any other time during the last 400,000 years. Temperatures at Vostok during that time have been flat to down.

The implication is that climate sensitivity is zero, and that past (lagging) changes in CO2 are are due to outgassing and absorption of CO2 by the oceans.

Why is this obvious fact being ignored by climate scientists?
