We already are well familiar with the shape of the hockey stick, so familiar in fact it has become an icon.
It has already been concluded by Marcott et al that their results should now show no modern uptick i.e. no Hockey Stick blade. As Richard Drake notes at Climate Audit the new look graph is like a scythe. An appropriate metaphor for those who are now reaping what they sowed for so many years.
Then of course there is the specter of what happens to humanity when the world cools.
