"The graphs of CO2 increase that I've seen don't bear any resemblance to an exponential curve."

Depends on your selected time scale:

"Depends on your selected time scale"

True. And I was referring to the actual CO2 measurement data (Mauna Loa), not the combined curve of ice-core plus Mauna Loa, which does look exponential.

Depends on your selected time scale:

Not to mention the scale of your y-axis, which is carefully chosen in all of your examples to exaggerate any trends.

I dare you to show a graph with zero at the y-origin, but then that wouldn't show your hysterical trend, would it?

One thing that is interesting from the Lampedusa Island, Italy CO2 concentration data, is that it is very cyclical with a single year period. Obviously, the CO2 spikes in the summer, when it is warm, and drops dramatically in the winter, typically the min-to-max range is 10-15 ppm. obviously, warm temperatures cause the CO2 level to spike, while the colder winter temperatures cause the CO2 levels to dip. This further suggests that it is temperature that is driving CO2 concentrations instead of CO2 concentrations driving temperature. If it were CO2 concentrations driving temperatures, there should not be an oscillation of the CO2 concentrations in such a cyclical fashion.

One more for you.
