The model has hysteresis for some parameter settings, so its climate is not always unique.

We do not question the reality of mechanisms that cause ice sheet hysteresis, but we suspect they are exaggerated in models.

Thus, as an extreme alternative that can be compared with ice sheet models and real - world data, we assume that hysteresis effects are negligible in our approximation for sea level as a function of temperature.

Ice sheet response time is poorly defined, but we show that the slow response and hysteresis in prevailing ice sheet models are exaggerated.

And in either scenario, I want to know what the models can say about the hysteresis in the system: how much ice lost at higher carbon - dioxide levels does not come back at lower ones.

Altogether, the empirical data support a high sensitivity of the sea level to global temperature change, and they provide strong evidence against the seeming lethargy and large hysteresis effects that occur in at least some ice sheet models.

More elaborate and accurate approaches, including use of models, will surely be devised, but comparison of our result with other approaches is instructive regarding basic issues such as the vulnerability of today's ice sheets to near - term global warming and the magnitude of hysteresis effects in ice sheet growth and decay.

Timothy Merlis, I believe gave a presentation in AGU last fall that had some measurements of hysteresis from a climate model.

What is the best evidence from GCMs or other kinds of models that there is hysteresis or multiple equilibria at this point?

You probably know this but it's worth pointing out that some more complex models (e.g., CCSM3, e.g., Liu et al 2009) do not exhibit AMOC hysteresis behavior (although see Hawkins et al., GRL).

«Altogether, the empirical data support a high sensitivity of sea level to global temperature change, and they provide strong evidence against the seeming lethargy and large hysteresis effects that occur in at least some ice sheet models.»

And, current ice sheet models exhibit implausible hysteresis (they're too lethargic), i.e. SLR is likely to happen much sooner than expected.
