Much of what you say is true. We could theoretically still avoid catastrophic change and stay below 1.5 degrees but I’m increasingly doubtful of that after COP26 and pitiful net zero (instead of net negative) commitments

Solar Geoengineering is something that could be considered. It is underfunded these days but we should do a better job of studying & modeling it’s effects if we ever hope to deploy it. Heck I think these island nations should deploy geoengineering techniques today. Albeit that last statement is partially in jest because the technology isn’t there yet. (It could have downstream consequences in the rest of the world, but clearly the rest of the world has geoengineered the climate using fossil fuels. These nations deserve a chance to protect their homes even if the method is drastic.)

That would require a high degree of international trust and cooperation (as it could be turned into a super weapon with only a little imagination). For something like that to happen, there often needs to be a clear and unambiguous external threat that is ‘worse’
