New York’s coastal populations and infrastructures are in danger due to the cause of climate change effects on sea levels rising up. It leads to storms and floods of greater intensity and frequency. This phenomenon results from numerous events, including changes in ocean currents, massive ice sheet and glacier loss, and thermal expansion, a process in which the ocean’s volume increases due to its warmer temperatures. 

Coastal zones of major regions of New York and the metropolitan area, as well as their vital structures, including international airports and local transit and communication systems, have become highly vulnerable and subject to immense damage.
