The melting of glaciers and ice sheets is another major contributor to rising oceans. Scientists call this process “thermal expansion,” and it’s responsible for about 40% of global sea level rise in the last 25 years. Heat trapped by greenhouse gases in the atmosphere is absorbed by the oceans, causing seawater to expand. The rate over the last quarter century (1.0 ft/century) was about twice as fast. Research conducted at Rutgers University indicates that global sea level rise in the 20th century (about 0.5 ft/century) was the fastest in at least 3,000 years. Even more concerning, the rate of sea level rise is accelerating. Sea level at the Jersey Shore has risen about 18 inches since the early 1900s, more than twice the global mean of about 8 inches. Sea level rise poses a threat to people and property in coastal areas around the world and is especially acute in New Jersey.
