global sea level record

Global sea level records track how the average height of Earth's oceans changes over time. These records are based on precise measurements from satellites, tide gauges, and other instruments. Factors influencing sea level include the melting of ice sheets and glaciers, the thermal expansion of seawater as it warms, and land movements. Monitoring these changes helps scientists understand climate change impacts and informs coastal management. While sea levels have generally risen over the past century, regional variations occur due to factors like ocean currents and land elevation changes. Overall, sea level records provide critical insights into our planet's evolving climate system.
