Talk to a climatologist, and they'll tell you all sorts of things you don't want to hear.

> In the face of all these uncertainties, some have taken a different predictive approach. Instead of trying to model the physics behind every process contributing to sea level rise (from thermal expansion to melting ice), they argue, why not instead simply look at how sea levels have corresponded to temperature over hundreds of years and extrapolate? These so-called 'semi-empirical' models tend to top out twice as high as the 'process-based' models, making 2 meters of sea level rise feasible for 2100 — enough to flood the homes of 187 million people. But the IPCC says it doesn’t have much confidence in these results. "They’re interesting," says Chambers, "but I don’t think they should be given as much weight as the process-based models."
> A few scientists disagree, including Stefan Rahmstorf of the Potsdam Institute for Climate Research, who works on semi-empirical models. "We have two different approaches, and they give different results," says Rahmstorf. "I don’t know which one is closer to the truth. But I object to the IPCC selecting one type and dismissing the other." Other reports, notes Rahmstorf, including a 2012 assessment by the U.S. National Oceanic and Atmospheric Administration, give more pessimistic sea level predictions, going up to 2 meters by 2100.
