Meltwater pulses (MWPs) known as abrupt sea-level rise will inevitably affect cities especially those on coastal plains of low elevation. A recent study presented evidence of abrupt sea level change between 11,300-11,000 years ago in the Arctic Ocean, solving the puzzle of second largest meltwater pulse (labelled as ”MWP-1B” next to the largest and already well understood MWP-1A).
