Coastal Flooding Damage: $1 Trillion a Year by 2050


Coastal Flooding

Almost all cities facing the worst damage are in Asia and North America, the study showed. Three American cities — New York, New Orleans and Miami — are at particularly high risk of damage, according to the study, published today (Aug. 18) in the journal Nature Climate Change.

Under pressure: raising Venice above water (using… water?)


Two factors are exacerbating the flooding risk to the city: global sea level rise and subsidence. In short, sea is rising and the city is sinking. Like other cities built on river deltas, the sediment beneath the city is compacting over time. In a natural setting, this compaction would be offset by the deposition of fresh sediment at the surface, but the rivers feeding the lagoon were diverted in the 1500s. As a result, the land surface is sinking, and the salt marshes are suffering for it.

I won't spoil on how exactly water is being used solve Venice's water problem.
