Coastal erosion: Brazil battles rising sea levels due to climate change

Brazil, which is hosting the COP30 summit in the Amazon in November, is facing a worrying rise in sea levels due to global warming. Sea levels in the village of Atafona, in the north of Rio de Janeiro state, could rise some 21cm by 2050, according to UN forecasts. The village is experiencing one of the world’s most serious environmental disasters due to coastal erosion. Every year, the sea advances by an average of six metres. Across the country, over 2 million people could be affected in the long term by rising sea levels. In Santos, in the state of Sao Paulo, the mayor’s office is trying to anticipate matters in order to avoid an economic and human catastrophe. FRANCE 24’s Louise Raulais and Jan Onoszko report.
