Right. So your first graph shows a bunch of lines, left unlabeled for our inconvenience, but some holding more or less steady above 20° and some gradually sliding from 20° to 10° over the last ten millennia, and some fluctuating near 0° all showing a sharp jump at the end.
So you’d guess an appropriate combination, even something simple like the mean, might end up showing a long decrease and sharp jump. Which is pretty much what Mann’s graph shows, but of course we should trust it doesn’t work out, with your usual graphs-not-stats analysis. Well, sorry, but your past arguments leave you very far behind Science as far as trust and doublespeak goes.
