They report in the journal Climatic Change that, if humans continue to burn fossil fuels at an accelerating rate, and as average global temperatures creep up by the predicted 4 °C above historic levels, then on the hottest days, between 10 % and 30 % of fully - loaded planes may have to remove fuel, cargo or passengers before they can take off: either that, or flights will have to be delayed to the cooler hours.

So, they didn't actually simulate sea level changes, but instead estimated how much sea level rise they would expect from man - made global warming, and then used computer model predictions of temperature changes, to predict that sea levels will have risen by 0.8 - 2 metres by 2100.
