Venice underwater

The city’s famous Piazza San Marco was flooded by more than three feet of water, according to Italian news agency ANSA, and the water level could rise to as much as five feet. While flooding is a complex phenomenon with many causes, the effects of climate change on sea-level rise, and the intense rainfall that comes with the greater capacity of a warming atmosphere to hold more moisture, are increasingly recognized as factors that can boost natural variation in weather patterns.
