People walk past a cyclone shelter in the coastal village of Gabura, in Satkhira district, Bangladesh on Oct. 6, 2021. The effects of global warming, particularly increased cyclones, coastal and tidal flooding that bring saltwater further inland, are devastating Bangladesh and destroying the livelihoods of millions, said Mohammad Shamsuddoha, chief executive of the Center for Participatory Research Development, a non-profit. He said that projections show that around 30 million people may be displaced from the country’s coastal regions. “It’s a grave concern for a country like Bangladesh,” he said.
