what cities will be underwater due to global warming

Torrential rains fill up the lower areas of the city and poor drainage systems do little to mitigate severe flooding events, which can sometimes persist for up to two months.įigure 1: Earth.Org Sea Level Rise Projections by 2100 for two scenarios with the amount of rise in metres indicated (mild = 3m extreme = 5m). Yet the situation is expected to get worse.Īccording to the Organisation for Economic Co-operation and Development (OECD), 5 out of the 10.7 million people living in Bangkok could be exposed to flood risk by 2070 and the government’s continued inaction is slowly turning this scenario into reality. Following the deadly floods of 2011 – which cost the lives of hundreds of people – a fifth of the city was reportedly underwater. The low-lying city – which has an average elevation of 1.5 metres above sea level – is already paying the price for this climate change-induced phenomenon. Sea level rise projections put Thailand’s capital as the world’s most vulnerable city. We take a look at the top 10 cities in the world most at risk of sea level rise flooding impact, according to the 2050 Climate Change City Index. According to sea level rise projections, nearly one billion people will be exposed to much greater risks of flooding by mid-century.

The Intergovernmental Panel on Climate Change (IPCC) forecasts that by 2100, sea levels could be as much as 1.1 metres higher than they are today and no amount of emissions reduction can stop the near and mid-term impacts of this phenomenon.
