When Additions Don't Help?

It was scary enough, when the Intergovernmental Panel on Climate Change (IPCC), used modelling to predict that the current rate of global heating would produce a 1.1 m increase in sea level by 2100. Most of the world's human populations are clustered around the current coasts. Island nations and low-lying parts of the globe would also be threatened. Food production would be devastated. A study from the University of Copenhagen's Niels Bohr Institute suggests the IPCC model needs tweaking to take into account past changes in sealevels (https://www.theguardian.com/environment/2021/feb/02/sea-level-rise-could-be-worse-than-feared-warn-researchers). The Niels Bohr Institute's model predicts, in a worst case scenario, sea level rises that are faster and greater than those predicted by the IPCC. They estimate a rise of 1.35 m by 2100. If their new model is correct (and the authors appear confident), we need even faster action to mitigate climate change.
