... the debate became even more intense, as the close associations of the ups and downs of atmospheric CO2 and temperature that were evident during glacial terminations and inceptions in that record, as well as in subsequent records of even greater length, led many climate alarmists to claim that those observations actually proved that anthropogenic CO2 emissions were responsible for 20th-century global warming.

This contention was challenged by Idso (1989), who wrote -- in reference to the very data that were used to support the claim -- that "changes in atmospheric CO2 content never precede changes in air temperature, when going from glacial to interglacial conditions; and when going from interglacial to glacial conditions, the change in CO2 concentration actually lags the...
