The following article in Nature Communications received a little attention, but not much:

Committed sea-level rise under the Paris Agreement and the legacy of delayed mitigation action

Sea-level rise is a major consequence of climate change that will continue long after emissions of greenhouse gases have stopped. The 2015 Paris Agreement aims at reducing climate-related risks by reducing greenhouse gas emissions to net zero and limiting global-mean temperature increase. Here we quantify the effect of these constraints on global sea-level rise until 2300, including Antarctic ice-sheet instabilities. We estimate median sea-level rise between 0.7 and 1.2 m, if net-zero greenhouse gas emissions are sustained until 2300, varying with the pathway of emissions during this century. Temperature stabilization below 2 °C is insufficient to hold median sea-level rise until 2300 below 1.5 m. We find that each 5-year delay in near-term peaking of CO2 emissions increases median year 2300 sea-level rise estimates by ca. 0.2 m, and extreme sea-level rise estimates at the 95th percentile by up to 1 m. Our results underline the importance of near-term mitigation action for limiting long-term sea-level rise risks.

It’s actually bad news.

First, in reality the limits proposed in the Paris Agreement are not going to be reached.

But even if the most aggressive limits are met, as noted with keeping net GHG emissions at zero for a full two and a half centuries, the warming we have already bought will cause sea level to rise about 1.3 meters over a couple of centuries.

Sadly, even the tame attempts at limits laid out in the Paris Agreement are not being taken seriously by the US, or Russia, or really OPEC. If the owners of the major carbon deposits don’t want to stop fossil fuel production, then the resultant sea level rises will be much higher than if we had made an earnest attempt at mitigation.
