Sea level is the level occupied by the top of the world's oceans. It is a reference point that is often used to define elevation.
- Sea level has been rising at a rate of 1.8 mm per year for the past 8,000 years. The IPCC notes that “No significant acceleration in the rate of sea level rise during the 20th century has been detected.” [1]
Storm surge
- The storm surge of a hurricane is not a wave, but rather it is a building of the ocean due to the wind. A storm surge occurs due to the extremely low pressure, and the immense drag exerted by the wind on the water, causing it to pile up several meters above the rest of the surface. [2]
