The Next 30 Years
Sea level along the U.S. coastline is projected to rise, on average, 10 - 12 inches (0.25 - 0.30 meters) in the next 30 years (2020 - 2050), which will be as much as the rise measured over the last 100 years (1920 - 2020). Sea level rise will vary regionally along U.S. coasts because of changes in both land and ocean height.
Breaking it Down:
Rise in the next three decades is anticipated to be, on average: 10 - 14 inches (0.25 - 0.35 meters) for the East coast; 14 - 18 inches (0.35 - 0.45 meters) for the Gulf coast; 4 - 8 inches (0.1 - 0.2 meters) for the West coast; 8 - 10 inches (0.2 - 0.25 meters) for the Caribbean; 6 - 8 inches (0.15 - 0.2 meters) for the Hawaiian Islands; and 8 - 10 inches (0.2 - 0.25 meters) for northern Alaska.
Evaporation drives the water cycle
Most of the moisture in the atmosphere (about 90%) came from water evaporating from oceans, seas, lakes, and rivers. (And because over 70% of Earth’s surface is covered by oceans, they contribute a lot to the overall volume of water evaporating into the atmosphere.) The rest of the moisture in the atmosphere came from plant transpiration and (a very small amount) from sublimation.
On a global scale, the amount of water evaporating is about the same as the amount of water delivered to the Earth as precipitation.
Evaporation is more prevalent over the oceans than precipitation, while over the land, precipitation routinely exceeds evaporation. Most of the water that evaporates from the oceans falls back into the oceans as precipitation. Only about 10 percent of the water evaporated from the oceans is transported over land and falls as precipitation. Once evaporated, a water molecule spends about 10 days in the air. The process of evaporation is so great that without precipitation runoff, and groundwater discharge from aquifers, oceans would become nearly empty.
