A 2013 study finds that reducing global greenhouse gas emissions avoids the risk of storms with Hurricane Sandy-like strength occurring roughly every year by 2050 along coastal regions in Virginia, Maryland, Delaware, and New Jersey.
The study shows that if no global action is taken, sea level rise will cause the annual odds of a Hurricane Sandy-strength storm hitting Atlantic City to increase from roughly 1-in-25 today to about once a year by 2050, but if we do significantly cut emissions, the odds increase to a more manageable 1-in-10.
Hurricane Sandy's $60 billion cost is greater than the entire proposed annual budget for the U.S. Department of Homeland Security for 2017.
An EPA study estimates that a significant global reduction in greenhouse gas (GHG) emissions can avoid at least $235 billion in annual damages in the U.S. by 2050.
The biggest benefit comes from public health improvements ($200 billion annually) such as improved air and water quality, fewer heat-related deaths, and increased labor productivity.
By 2100, EPA estimates global GHG reduction could result in at least $1.2 trillion in annual avoided damages in the U.S., mostly from improved air quality.
