Sea Levels & Climate Change
The world’s climate fluctuates as a result of changes in the sun’s activity affecting the polar ice caps, the dome-shaped sheets of ice found in Greenland and Antarctica.
These effects occur gradually over time, making sea levels change as ice caps melt or cool. This cycle of cold and warm periods has repeated itself several times over the past two million years. Since 10,000 years ago, sea levels have risen to make Jersey an Island once more.
