WASHINGTON — The number of people threatened by climate change-triggered flooding is about three times higher than previously thought, a new study says. But it’s not because of more water.
It’s because the land, especially in Asia and the developing world, is several feet lower than what space-based radar has calculated, according to a study in the journal Nature CommunicationsTuesday.
So instead of 80 million people living in low-lying areas that would flood annually by 2050 as the world warms, this new study finds the population at risk is closer to 300 million people.
And if emissions of heat-trapping gases continue unabated and Antarctic ice melts more in a worst-case scenario, around 500 million people could be at risk by the end of the century, according to the study by Climate Central , a New Jersey based non-profit of scientists and journalists.
