    Tapdancer, i would reckon Glikson’s assertion that the 500-600 ppm CO2 equivalent range is a stability threshold for the Antarctic and Greenland ice sheets probably derives from his professional expertise.

    it could therefore be absolutely spot on. Time will tell. I doubt Glikson would just pull random numbers out of the air to help build his case. I don’t think science works that way.

    His academic background and ongoing publishing work on the impact of AGW and climate change suggests to me he’s credible, plausible and exactly the sort of expert i should turn to find out more about the issue.
