Mean sea level projection (Intermediate greenhouse gas emissions scenario (SSP2-4.5)) for Hong Kong

Mean sea level projection (Intermediate greenhouse gas emissions scenario (SSP2-4.5)) for Hong Kong

Mean sea level
Intermediate greenhouse gas emissions scenario (SSP2-4.5)

Projected changes in annual mean sea level in Hong Kong relative to the average of 1995-2014 under the Intermediate greenhouse gas emissions scenario.

Projected change in annual mean sea level in Hong Kong relative to the average of 1995-2014. The solid curve and shading show respectively the median and the likely range of projection under the intermediate greenhouse gas emissions scenario (SSP2-4.5). The probability for the likely range to cover the outcome is at least 66%. (Data source: IPCC AR6)
