Benefits of mitigation if there is no adaptation; showing the Priority Places where the largest impacts on biodiversity are projected. Comparison at 2 and 4.5 °C global warming expressed in terms of (a) Priority Places for which 75% of their area can operate as a refugium for up to five taxa. The maximum number is 5 (i.e. plants, birds, mammals, reptiles, amphibians). Priority Places are arranged in order of decreasing climate change impacts. Impacts are greatest where no refugia remain (blank Priority Places at the top of the chart) and lowest where they remain even at 4.5 °C (purple bars at the bottom of the chart). Many more refugia remain at 2 °C than at 4.5 °C (middle and bottom of chart). The areas with the longest green bars are the ones which benefit the most from constraining warming to 2 °C: they have few or no refugia at 4.5 °C and three to five at 2 °C. (b) The average (across taxa) area of a Priority Place that can operate as a refugium. Many more areas acting as refugia remain at 2 °C than at 4.5 °C (middle and bottom of the chart). The areas with the greatest difference between purple and green bars are the ones which benefit more from constraining warming to 2 °C: they have few or no refugia at 4.5 °C and many at 2 °C
