Temperatures are breaking records around the world. In fact, Earth’s global surface temperatures in 2017 ranked as the second warmest since 1880, according to an analysis by NASA. When temperatures rise, ice melts and water from glaciers and ice caps flows to the seas. When ocean water warms, it expands in volume and, consequently, sea level rises. Warmer seas also mean more precipitation, and sea level rise is more likely to make future coastal storms, including hurricanes, more damaging.  It is no coincidence that hurricanes occurring in some regions including the North Atlantic have increased in intensity over the past two to three decades.
