Sea level in the IPCC 6th assessment report (AR6)

Real Climate

My top 3 impressions up-front: The sea level projections for the year 2100 have been adjusted upwards again. The IPCC gives more consideration to the large long-term sea-level rise beyond the year 2100. And here is the key sea-level graphic from the Summary for Policy Makers: Source: IPCC AR6, Figure SPM.8.

Sea level rise is a big deal Use, abuse and misuse of the CMIP6 ensemble The radiative forcing bar chart has gone full circle Droughts and floods are complicated Don’t mention the hiatus. Sea Level Rise: The previous IPCC reports, notably AR4 and AR5 (to a lesser extent) , have had a hard time dealing with SLR.

While temperatures provide a measure of the Earth’s climate, it is even better to use the global sea level , which provides a far more reliable measure. The global sea level acts like the mercury in a thermometer because warmer water expands.
