Climate change is also exacerbating the problem of flooding in cities. As global temperatures rise, so do sea levels, increasing the risk of coastal flooding. Additionally, extreme weather events, such as hurricanes and heavy rainfall, are becoming more frequent and severe, leading to more frequent and severe flooding in cities around the world. In recent years, there have been several high-profile instances of flooding in cities around the world. In 2005, Hurricane Katrina caused catastrophic flooding in New Orleans, Louisiana, resulting in over 1,800 deaths and billions of dollars in damage. In 2011, heavy rainfall in Bangkok, Thailand, led to massive flooding that affected millions of people and caused billions of dollars in damage.
