The three-degree world: cities that will be drowned by global warming

The UN is warning that we are now on course for 3C of global warming. This will ultimately redraw the map of the world

When UN climate negotiators meet for summit talks this month, there will be a new figure on the table: 3C.

Until now, global efforts such as the Paris climate agreement have tried to limit global warming to 2C above pre-industrial levels. However, with latest projections pointing to an increase of 3.2C by 2100, these goals seem to be slipping out of reach.
