1.41m by 2100 is the projection for “Grand Isle”, the closest location in the model to New Orleans. Sea level and sea level rise is not uniform worldwide, so local predictions are very important. This is also true for temperature and other climate change impacts, and is one of the biggest improvements in the latest IPCC report.

It looks like all model scenarios agree fairly well out to 2100 both in the global projections and in projections for Grand Isle. Thus, I’d wager good money that New Orleans will see 1-2m sea level rise by 2100 regardless of any climate mitigations we perform.

Grand Isle (which Ida did a number on) is well south of NOLA in Jefferson Parish, and not part of the metro area. It exists for fishing and tourism.
