Did it actually say it will DOUBLE the CO2 concentration? Definitely past the point of no return. I guess us millennials WILL actually see the worst climate change outcomes WELL within our lifetimes...

In climate science parlance it means it's a conservative guess and will likely happen faster than anticipated.

'Net increase in land area of 2.9%'

'Land area increase in eight of nine atolls. Island change has lacked uniformity with 74% increasing and 27% decreasing in size.'

'Results challenge perceptions of island loss, showing islands are dynamic features that will persist as sites for habitation over the next century, presenting alternate opportunities for adaptation that embrace the heterogeneity of island types and their dynamics.'

Also: "Sea-level rise and climatic change threaten the existence of atoll nations. Inundation and erosion are expected to render islands uninhabitable over the next century, forcing human migration"
