Whats the really cool bit of data on that graph.
The global temperature.
And recorded history, let me show it to you.

Geology
Atmospheric carbon dioxide levels for the last 500 million years

The last 500 million years of the strontium-isotope record are shown to correlate significantly with the concurrent record of isotopic fractionation between inorganic and organic carbon after the effects of recycled sediment are removed from the strontium signal. The correlation is shown to result from the common dependence of both signals on weathering and magmatic processes. Because the long-term evolution of carbon dioxide levels depends similarly on weathering and magmatism, the relative fluctuations of CO2 levels are inferred from the shared fluctuations of the isotopic records. The resulting CO2 signal exhibits no systematic correspondence with the geologic record of climatic variations at tectonic time scales.

In terms of weighted for greenhouse strength the human contribution is .28% of the greenhouse effect.

It is about 0.28%, if water vapor is taken into account-- about 5.53%, if not.
Keep chasing that rainbow guys.
I'm more than willing to talk about the effects of potential climate change, but those are I know are boring and non-political. What to do if it gets warmer, colder, if areas get a drought etc.
