Sea Level Rise: the rise in long-term ocean/sea levels relative to local land levels along the coastline; impacted by the increase in melting land ice (glaciers, ice sheets), the expansion of ocean water as it warms (warmer water is less dense), and to some extent, sinking land (subsidence).
Sea Level rise is an issue in many coastal areas and major cities around the world, including New York City, which sits just 33' above sea level, with some vulnerable areas sitting even lower. The Hudson River Estuary, often referred to as an "arm of the sea" is also impacted by sea level rise, along with its many river towns & cities. As the level of the Atlantic Ocean rises, it impacts these coastal areas in many ways.
