1. Thermal Expansion: As the Earth's temperature increases due to global warming, ocean water expands, leading to a rise in sea levels.
2. Melting Glaciers and Ice Sheets: As the global temperature rises, the ice mass from glaciers and ice sheets in Greenland, Antarctica, and other regions melt, leading to increased water entering the oceans.
3. Reduced Water Storage on Land: Deforestation and unsustainable water usage deplete surface and groundwater storage, preventing water from reaching the oceans and contributing to higher sea levels.
4. Changes in Oceanic Processes: Shifts in ocean currents and wind patterns can impact sea level. For example, changes in the Atlantic Meridional Overturning Circulation (AMOC) can alter sea levels along coastal regions.
