A future of more extreme floods, brought to you by climate change


Extreme floods along the coastline may become much more common if sea levels continue to climb unchecked, new research says. Scientists estimate that as soon as 2030, a 4-inch sea level rise could double the frequency of severe flooding in many parts of the world, and increase it by as much as 25 times in the tropics. For the communities and ecosystems in the floodwaters’ path, the toll could be catastrophic.

Right now, the global sea level is slowly but surely creeping upwards a fraction of an inch each year (0.118 to 0.157 inches per year to be exact). That doesn’t seem like much, but we’re already feeling the consequences of rising waters and eroding coastlines. Tides high enough to flood homes and infrastructure have become more…
