" . . . what would be the difference between a 1.5 and 2 degree world? And how realistic is such a target?
"By some estimates, curbing warming at 1.5 degrees could be sufficient to prevent the formation of an ice-free Arctic in summer, to save the Amazon rainforest, and to prevent the Siberian tundra from melting and releasing planet-warming methane from its frozen depths. It could also save many coastal regions and islands from permanent inundation by rising sea levels, particularly in the longer run."
