Research Claims IPCC Underestimated Sea Level Rise Potential by 2100

While the most recent reports by the Intergovernmental Panel on Climate Change said the sea level was unlikely to rise by more than 1.1m (3.6 feet) by 2100, climate researchers from the University of Copenhagen’s Niels Bohr Institute believe levels could rise as much as 1.35 metres by 2100 under a worst-case warming scenario. Using historical data on sea level rise to validate various models relied on by the IPCC to make its assessment, they found a discrepancy of about 25cm, which they've published in the most recent article of the journal, Ocean Science.


They claim the models used to base predictions of sea level rise are not sensitive enough, and they hope their testing method could be used to constrain models, make them more credible, and reduce uncertainty. The IPCC sea level scientists have been sent the paper for review.

This is alarming news for low-lying island states, and underscores the need for rapid action to address changing climate trends and curb global temperature rise.
