Based on the anticipated greenhouse gas concentration by the end of the 21st century a team of researchers in the US (Stevens Institute of Technology, Princeton University) conducted high resolution simulations for different scenarios to find the probability of different flood levels being reached, assuming emissions remain at a high level. They studied how sea level rise and hurricane climatology change would impact the area in the future due to storm surge and wave hazards. They found that the historical 100-year flood level would become a nine-year flood level by mid-century (2030-2050) and a one-year flood level by late 21st century (2080-2100). Additionally, sea-level rise would result in larger waves which could lead to more flood hazards such as erosion and damage to coastal infrastructure. The increase in these once-in-a-generation or even less frequent floods is so dramatic because the impact of sea-level rise will create greater flooding, even if the storms we were seeing today stayed the same…read more.
