Satellite laser ranging revealed ocean mass growth as the main driver of rising seas. Melting land ice now dominates sea-level change. The increase in global mean sea level (GMSL) is a key signal of climate change. Researchers at The Hong Kong Polytechnic University (PolyU) have applied advanced space-based geodetic methods to produce the first accurate […]



Summary

Satellite laser ranging analysis confirms that ocean mass growth, driven by melting land ice, is the primary contributor to rising global mean sea level (GMSL), a critical indicator of climate change. A new study by researchers at The Hong Kong Polytechnic University (PolyU) utilizes advanced space-based geodetic techniques to accurately measure these changes. Their findings highlight the significant impact of melting glaciers and ice sheets on ocean mass and its direct correlation to sea-level rise.
