but there is almost certainly more scientific evidence of anthropogenic climate change

Such as - for instance - the IPCC hockey stick graph? The mishmash of heterogenous modelling methods that gave a graph of climate history that somehow missed out the mediaeval warm period and the little ice age? That scientific evidence?

You seem to have your talking points down at least.

Of course you realize that "hockey stick graph" is just the dumbed down American version of an exponential growth curve more intelligently noted as "x squared".

In the other points you mentioned, both were accompanied by increases in CO2 concentration far below what we are currently seeing and the temperature shift far slower than current trends.

If you would like to extrapolate back several more millions of years, you can find CO2 concentrations similar to what we have now and a much warmer planet.

Of course anything that goes back earlier than 2 million years is of little value because that is when North and South America joined and we had separation of the Atlantic and Pacific, drastically altering global weather patterns and therefore vegetation respiration.
