Values indicate projected length of suitable habitat under current conditions (row 1), under projections for the 2080s A1B composite scenario (row 2), and under the 2080s A1B composite scenario with selected climate metrics held constant at current levels (rows 3–6). Units are km × 1,000. Values in parentheses indicate change relative to the 2080s A1B composite scenario (row 2).
