Global mean sea levels have increased by around 25 centimeters since 1880 - Our World in Data

Since 1880, global mean sea levels have risen by approximately 25 centimeters, a significant indicator of climate change and its impact on our oceans. This rise reflects a combination of factors, including thermal expansion due to warming waters and melting ice sheets. Understanding these changes is crucial for developing effective mitigation strategies and enhancing our resilience to future sea level rise.
