DURING PAST ICE AGES CO2-LEVELS WERE LOW, AND DURING WARM PERIODS CO2- WAS HIGHER
https://skepticalscience.com/co2-higher-in-past-intermediate.htm Do high levels of CO2 in the past contradict the warming effect of CO2? What The Science Says: Climate and CO 2 levels have always varied together. During past ice ages CO 2 levels were low, and during warm periods CO 2 was higher. The rock “weathering thermostat” prevents a runaway climate on very long timescales. Climate Myth: CO2 was higher in the past "The killer proof that CO2 does not drive climate is to be found during the Ordovician- Silurian and the Jurassic-Cretaceous periods when CO2 levels were greater than 4000 ppmv (parts per million by volume) and about 2000 ppmv respectively. If the IPCC theory is correct there should have been runaway greenhouse induced global warming during these periods but instead there was glaciation." ( The Lavoisier Group ) Climate closely matches CO 2 throughout the geological record Figure 1: Temperature (top) and CO 2 (b...
