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.

Why is future sea level rise still so uncertain?

Real Climate

Three new papers in the last couple of weeks have each made separate claims about whether sea level rise from the loss of ice in West Antarctica is more or less than you might have thought last month and with more or less certainty. 2020) or Sadai et al.

Rising land under Antarctica could slow sea level rise

New Scientist

Antarctica’s melting ice sheet is relieving pressure on the land beneath, allowing it to push upwards in a way that could slow sea level rise in coming centuries – but only if greenhouse gas emissions are low

Deciphering the ‘SPM AR6 WG1’ code

Real Climate

The cause of our changing climate is the increase in atmospheric greenhouse gas concentrations that we have released into the air. Carbon dioxide (CO 2 ) is the most important greenhouse gas that we have added to the atmosphere, however, some of it has been absorbed by land and oceans. mm increase every year.
