It would seem as though your own graphs here shoot themselves in the foot.
How could human-induced carbon dioxide shoot up so fast, while antarctic surface temperatures fall below what should be expected?
And how do you get 1000 ppm carbon dioxide from ice samples, if the supposed time period for the sample had no ice at all?
And why aren't you showing total cryosphere ice, instead of arctic sea ice?
And why are you assuming that carbon dioxide and temperatures are causally related? This has not been proven, and you know it.
Oh, and
Politifact is not exactly a reliable source, either.
