Even under the most optimistic scenarios outlined in the Paris Agreement—keeping the overall warming of Earth to 1.5 degrees (Celsius) - sea levels will continue to rise by several meters over the next few thousand years. If humans continue to burn fossil fuels so that temperatures meet the 2-degree (Celsius) threshold outlined in the Paris Agreement, global mean sea level rise may exceed nine meters, or nearly 30 feet.

Results of the study have been published today in Nature Climate Change.
