Ugh. I only hope that this gross misrepresentation is due to the
journalists rather than the actual contents of the IPCC report.
Incidentally I had a chat with several ice sheet modellers yesterday,
who explicitly supported the points I've made here recently - that is,
that a melt requires not only a temperature rise above some threshold
(significantly higher than today), but for the temperature to remain
above the threshold for hundreds of years subsequently. No doubt there
is some spectrum of opinion concerning the details (and everyone would
acknowledge there is uncertainty over the quantitative estimates) but I
am confident that this is by far the dominant view.
