"The collapse of major Antarctic ice shelves at the end of the century followed by increased discharge of ice may lead to a 9-10 meter catastrophic sea-level rise by 2300 under the same strong warming scenario. Fulfilling the Paris Agreement will greatly reduce the potential of high-end sea-level rise to 2.2-2.5 m, but not stop sea-level rise to 2300. Hence, we need to be prepared to both mitigate climate change and adapt in coastal areas—but such adaptation is feasible for this magnitude of change over multiple centuries in many places."
