Island of Saint-Louis

In 2022, the IPCC Sixth Assessment Report included the Island of Saint-Louis in the list of African cultural sites which would be threatened by flooding and coastal erosion by the end of the century, but only if climate change followed RCP 8.5, which is the scenario of high and continually increasing greenhouse gas emissions associated with the warming of over 4 °C.,^[3] and is no longer considered very likely.^[4][5] The other, more plausible scenarios result in lower warming levels and consequently lower sea level rise: yet, sea levels would continue to increase for about 10,000 years under all of them.^[6] Even if the warming is limited to 1.5 °C, global sea level rise is still expected to exceed 2–3 m (7–10 ft) after 2000 years (and higher warming levels will see larger increases by then), consequently exceeding 2100 levels of sea level rise under RCP 8.5 (~0.75 m (2 ft) with a range of 0.5–1 m (2–3 ft)) at some earlier point.^[7]
