Arctic Vegetation (IMAGE) DOE/Lawrence Berkeley National Laboratory Caption Current and predicted changes in areas around the world where vegetation responds strongly to warming. Shaded areas represent areas where vegetation growth was limited by cold temperatures at the start of the observational record (1982-1986) but was not by the corresponding year. Representative Concentration Pathway (RCP) 4.5 is a carbon emissions target to limit temperature increases to two degrees Celsius, while RCP 8.5 represents a scenario where carbon emissions are not limited and temperature increases exceed two degrees Celsius.
