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.

Do Paris Agreement Temperature Goals Address Sea Level Rise and Climate Justice?

Union of Concerned Scientists

Sea level rise presents numerous climate justice issues. New research that I led as part of my PhD dissertation, which was just published in Earth’s Future , digs deep into the topic of sea level rise and climate justice. Climate justice research can help inform these conversations.

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

Rising Seas, Rising Stakes: The Case for an International Court of Justice Advisory Opinion 

Union of Concerned Scientists

My research looks at issues of climate justice internationally, particularly as they relate to sea level rise and the Paris Agreement. Sea levels will continue to rise for hundreds of years from just the heat-trapping emissions that are happening today, and once they rise the levels will remain that way for thousands of years.
