Rapid and significant sea-level rise expected if global warming exceeds 2 °C, with global variation

The latest issue of Science for Environment Policy, features a study partly conducted under IMPRESSION's sister project RISES-AM, predicting the world could experience the highest ever global sea-level rise in the history of human civilisation if global temperature rises exceed 2 °C.

Under current carbon-emission rates, this temperature rise will occur around the middle of this century, with damaging effects on coastal businesses and ecosystems, while also triggering major human migration from low-lying areas. Global sea-level rise will not be uniform, and will differ for different points of the globe.

Sea-level rise is one of the biggest hazards of climate change. It threatens coastal populations, economic activity in maritime cities and fragile ecosystems. Because sea-level rise is a delayed and complex response to past temperatures, sea levels will continue to climb for centuries into the future, even after concentrations of greenhouse gases in the atmosphere have been stabilised.
