Unlock The Science Ep.29 Climate Threats to Urban Cities
Climate projections by various organizations have agreed that a hotter earth will contribute to a more volatile and more extreme climate pattern, in which natural disasters such as flood and drought, heatwave, wildfires, or powerful tropical storms will commonly occur. Thailand is one of the countries that has greatly suffered from climate disasters during the past two decades. Bangkok is extremely vulnerable to coastal flooding and storm surge, due to its location on low-lying river delta. Therefore, in the worst-case scenario, in which global warming is left unchecked, 96 percent of Bangkok could be under sea level by 2030. According to an estimation, if the world temperature increases up to two degrees Celsius in about 80 years from now, or by the year 2100, the world is going to suffer costs of damages from climate change of up to 69 trillion U.S. dollars, or slightly over three times of the current GDP of the United States. Discussing the issue of climate threats to urban cities are Renato Redentor Constantino, executive director of Institute for Climate and Sustainable Cities, which is based in Manila, the Philippines, and Asst. Prof. Dr. Suthirat Kittipongvises of Environmental Research Institute, Chulalongkorn University.
