Even if the ambitious 1.5C global warming target is met, scientists warn of potentially devastating sea-level rise of several meters over centuries. This is due to continued melting of Greenland and Antarctic ice sheets, whose response to temperature changes takes centuries. Current observations and models show accelerating ice melt, with potentially catastrophic consequences for coastal communities. While reaching 1.5C is crucial, it won't stop sea-level rise, highlighting the urgency of reducing emissions.
