What's wrong with that answer? It's perfectly correct. Coming out of the
last ice age, tilt and wobble increased the temperature slightly and this
produced more CO2 for the first 1/6 of the temperature change. After that,
the CO2 accelerated the temperature change for the remaining 5/6 of the
change. If all we had was tilt and wobble and no CO2 effects we would have
never come out of the ice age.
I do have a question for the deniers. Where is the massive
temperature increase 800 years ago that explains in the current 35% increase
in CO2? Wasn't the 13th Century the start of the Little Ice Age?
