Why are the world’s cities sinking?

A study has found that more than two dozen US coastal cities are
sinking by more than 2mm a year. It’s a similar picture across the
world. Nearly half of China’s major cities, as well as places such
as Tehran and Jakarta, are facing similar problems. These issues
are compounded by sea level rises caused by global heating.
Madeleine Finlay speaks to Prof Manoochehr Shirzaei of Virginia
Tech University and Prof Robert Nicholls of the University of East
Anglia to find out what’s making our cities sink and whether
anything can be done to rescue them from the sea. Help support our
