Note
Quantitative scenarios are coming of age as a tool for evaluating the impact of future
socioeconomic development pathways on biodiversity and ecosystem services. We analyze global
terrestrial, freshwater, and marine biodiversity scenarios using a range of measures including
extinctions, changes in species abundance, habitat loss, and distribution shifts, as well as
comparing model projections to observations. Scenarios consistently indicate that biodiversity will
continue to decline over the 21st century. However, the range of projected changes is much
broader than most studies suggest, partly because there are major opportunities to intervene
through better policies, but also because of large uncertainties in projections.
