Extra 23 million people could face coastal flooding within 30 years, even with emission cuts, study says. Human-caused sea level 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 sea level rise, storm surges and high tides could expose an extra 23 million people to coastal flooding within the next 30 years, even with relatively ambitious cuts to greenhouse gas emissions, a new global study has found. In a worst-case scenario where emissions continue to rise and no efforts are made to adapt to the rising sea levels, coastal assets worth US$14.2tn – about 20% of global GDP – could be at risk by the end of the century. Rising sea levels caused by global heating that expands the oceans and melts land-based ice could mean that one-in-100-year floods occurring now would become one-in-10-year floods by the end of the century. As much as 4% of the world’s population could be affected by flooding. The study, published in the journal Scientific Reports, identified “hotspot” regions at risk of extensive flooding. South-eastern China, Australia’s north, Bangladesh, West Bengal and Gujarat in India were especially at risk. In the United States, North Carolina, Virginia and Maryland were considered to be most exposed, as were the UK, northern France and northern Germany.
