Coastal flooding could hit nearly 20% of global GDP as climate change accelerates sea level rise
Coastal flooding made worse by climate change could damage assets worth up to $14.2 trillion by 2100 as rising seas inundate coastal homes and infrastructure, according to new research published in Scientific Reports.
A general view shows people walking across the flooded St. Mark's Square, by St. Mark's Basilica on November 15, 2019 in Venice, two days after the city suffered its highest tide in 50 years.Coastal flooding made worse by climate change could damage assets worth up to $14.2 trillion by 2100 as rising seas inundate coastal homes and infrastructure, according to new research published on Thursday in Scientific Reports.
"Globally we need to understand that changes of this nature will occur by 2100 and we need to plan how we are going to respond," he said. Razarbag Road in Dhaka is submerged by flood water following incessant monsoon rain which has inundated the capital's roads and crossroads throughout the down-town area. The monsoon has forced the evacuation of more than 1 million people.Island nations and countries with higher population density in low-lying coastal areas will be disproportionately affected.
Climate change is driving sea levels to rise at a rate of about one-eighth of an inch per year. Higher sea levels push storm surges further inland, which creates more destructive flooding along the coastlines. "Coastal areas are very susceptible to rising sea levels and climate change," said Ebru Kirezci of the University of Melbourne and an author of the research. "In order to prevent adverse effects of climate change and sea level rise, developing and tailoring adaptation strategies are necessary depending on the coastal hazard levels and the necessities of coastal communities."
