  1. Stop pushing the CO2 bs. 4000ppm during the Cambrian, 7000ppm during the Ordovician/Salurian Ice Age or Snowball Earth. CO2 actually dropped to lowest level ever recorded in the geological record just after the PE and matched only by todays low level. CO2 has no effect on temperature, it FOLLOWS not LEADS temperature changes.
