About This Data

This dashboard visualizes global mean sea level rise from 1880 to using three authoritative datasets:

• EPA/CSIRO (1880-2013): Combined Environmental Protection Agency and CSIRO data
• CSIRO Reconstructed (1880-2019): Historical tide gauge records
• Satellite Altimetry (1993-2020): High-precision satellite measurements

All measurements show change relative to the 1900 baseline.

Key Findings

• Sea levels have risen approximately inches since 1880
• The rate of rise has accelerated from ~0.6 in/decade (1900-1990) to ~1.2 in/decade (1993-)
• Highest annual increase: with + inches in a single year
• Years with largest increases: (top 5 years since 1900)
• Multiple independent datasets show consistent trends
• Satellite measurements (1993+) show the highest precision and confirm acceleration

Note: This shows global mean sea level. Local changes vary due to land subsidence, ocean currents, and regional climate patterns.
