Why will sea level rise not be the same everywhere?

Sea level is rising because of global warming, but this rise is not the same everywhere on Earth. Three factors influence the sea level changes locally:

  • Temperatures – Hot water is more voluminous than cold water, hence sea level may rise more in the Tropics.
  • Winds – The dominant winds in a region affect the shape of the seas.
  • Oceanic currents – Global warming can cause changes in oceanic currents, which would have a direct impact on local sea level rise.

The coastlines’ shape and the tectonic settings can also affect the response of a given location to sea level change.
