What does natural rate even mean? Without the influence of man? Here's the last 450,000 years, point to natural warming on this graph.

That you think this image is some sort of boom only proves you don't know how to read charts.

Divide 450,000 by 1576 (the pixel width of the graph portion as I just measured in paint) and you get 285.5. Every individual pixel on that graph stands for three centuries.

We've warmed a full degree in one century. That would be vertical with respect to the graph's scale, not simply steep. Plus it breaks the natural cycle illustrated by that chart since we're already at the crest of an interglacial and therefore would expect a slow cooling, not a double bump of even-more-rapid warming.

(The fact that it misspells "anomalies" and is sourced to climatedata.info rather than the actual EPICA paper is also a bit of a red flag, since skeptics tend to "accidentally" frick up baselines and such when "reproducing" these graphs. But I recognize the overall pattern so I'll work with the broad strokes for now.)
