Scientists uncovered that on average, most coastal areas worldwide will experience 100-year floods every nine to fifteen years until the end of the century.
Hamed Moftakhari, a civil engineer and professor at the University of Alabama and supervisor of the study, stated:
Usually, floods can be triggered by water being pushed inwards toward the land from the sea due to storms or tides and waves in coastal areas. The recent study aimed to identify a long-term triggering element leading to flooding over a long period and the role of rising sea levels. The scenarios involve a situation when carbon dioxide emissions continue to rise until the end of the century. Secondly, when emissions peak by 2040 and then decline upon climate action.
"In stationarity, we assume that the patterns we have observed in the past are going to remain unchanged in the future, but there are a lot of factors under climate change that are modulating these patterns," added Moftakhari. "We can't assume stationarity in coastal flooding anymore."
