Extra 23 million people could face coastal flooding within 30 years, even with emission cuts, study says

Human-caused rise, storm surges and high tides will put trillions of dollars of assets at risk around the world by the end of the century

The combined impacts of human-caused rise, storm surges and high tides could expose an extra 23 million people to coastal within the next 30 years, even with relatively ambitious cuts to , a new global study has found.
