    "Yes there is evidence that temperature rises have caused increased CO2 levels in ages past"

    Physics dont change regardless of what YOU want to believe.
    All but 3% of the current 415ppm of CO2 in the atmosphere is natural.
    CO2 is a greenhouse gas and adds to the natural warming that was occurring but it's effect is logarithmic and it's effect is now quite small.
