Sea levels might rise much faster than thought, Greenland data suggest
- david_allison 4y agoPredicted at least as far back as 2007 > Despite these early warnings about likely future nonlinear rapid response, IPCC continues, at least implicitly, to assume a linear response to BAU [business-as-usual: 3°C] forcings. Yet BAU forcings exceed by far any forcings in recent palaeoclimate history. > Part of the explanation for the inconsistency between palaeoclimate data and IPCC projections lies in the fact that existing ice sheet models are missing realistic (if any) representation of the physics of ice streams and icequakes, processes that are needed to obtain realistic nonlinear behaviour.

- givemeethekeys 4y agoAll this "may"ing and "might"ing is creating noise in an already noisy news cycle. We've been using words like, "may" and "might" in reporting scientific trends for a while now. There ought to be a tracker that does backtesting of such reports and re-reports the findings as, "yup, definitely happening".
