Summary

Story summary

A study from Hong Kong Polytechnic University reports a 90mm rise in global sea levels from 1993 to 2022, mainly from melting ice and thermal expansion.
Enhanced satellite laser ranging (SLR) has increased accuracy in measuring ocean mass, confirming ice loss as a key factor.
The results highlight the urgent need to address climate change effects on coastal areas.

History

Historical Context

The 2007 IPCC Fourth Assessment Report warned of significant climate change impacts, predicting a sea-level rise of 18-59 cm by 2100 due to melting ice sheets and thermal expansion. Confirmed by studies from Hong Kong Polytechnic University and Tulane University, which noted a 90mm rise from 1993 to 2022, this data highlights the urgent need for localized forecasts to protect vulnerable coastal regions like south Louisiana.
