Moreover, the tremendous amounts of meltwater produced could influence ocean currents, sparking massive changes in the climate, especially in the North Atlantic [...] accurately simulates the past, it can also project the future, paving the way for forecasts on e.g. future sea-level rise or global warming. In this way, these models provide the scientific basis for formulating [...] floodwalls and levees are costly. That’s why it’s important to be able to estimate today how much the sea level will rise, or how much the intensity of hurricanes will increase, tomorrow. Climate modeling
