Sea level rise – The part of climate change we can’t yet understand
Reading the new IPCC report that came out today my head turned about halfway through when reading:
“Due to deep uncertainty linked to ice-sheet processes, global 50 mean sea level rise above the likely range – approaching 2 m by 2100 and in excess of 15 m by 2300 under the 51 very high GHG emissions scenario (SSP5-8.5) (low confidence) – cannot be excluded”
(B3.3 – IPCC AR6 Synthesis Report: Climate Change 2023)
The problem is that of all the climate dynamics sea level rise is the one we understand the least…
We could be heading for a 4degrees temperature rise according to the IPCC and that has happened on Earth before:
As Gaia Vince writes in the book: Nomad century(2022):
“The world has reached a 4 degrees C hotter temperature before – well before humans appeared – some 15 million years ago, during the Miocene era, when intense volcanic eruptions in western North America emitted vast quantities of carbon dioxide. “Sea levels rose some 40 meters higher than today. “
So there are reasons the IPCC added that B3.3 part, and a good reason to #ActNow as the tag says
