The IPCC (InterGOVERNMENTAL Panel on Climate Change) cops a lot of stick for allegedly being radical, part of the great climate-science-greenie-leftie-jewish-commo conspiracy, etc. But in fact it is too slow and conservative, witness the world is tracking on the high side of its projections.
One IPCC habit that annoys me is running projections only to the year 2100. We know warming and its consequences won’t stop there, so the choice is pure bureaucratic nonsense.
Here is a rare example of a more useful graph, showing warming continuing for more than a century beyond 2100. God knows what sort of world our great- … – grandchildren would be contending with.
The 2100 cutoff makes even less sense for sea level rise. Current estimates are, from memory, 30-100 cm, but the rise will continue for many centuries and would level off at 7 m, 15 m, who knows?
In our monumentally selfish and myopic civilisation, our distant descendants count for nothing.
The graph is from an article by Stephan Lewandowsky here. He challenges the US denialist Matt Ridley, who interpreted this graph to mean that there would be “minimal warming that is beneficial for us”.
This claim was run by those well known clarions of free speech The Wall Street Jounal, The Australian, and Forbes.
The graph is originally from a paper by Professor Michael Schlesinger of the University of Illinois.
