All the model ensembles from Sixth Assessment Report of Intergovernmental Panel on Climate Change (IPCC).

Findings of the report

This report projects that, sea levels along the coastline will increase an additional 10-12 inches by 2050. Specific amounts will vary regionally, due to land height changes.
It updates the sea level rise projection in 2017 by federal government and provides additional information on wind, tide, and storm-driven extreme water levels that affects current and future coastal flood risk.
As per report, sea level rise will create a profound increase in frequency of coastal flooding, even in the absence of heavy rainfall or storms.

Significance of the report
