Projected climatic suitability for Ae. albopictus with climate change. Future climatic suitability for Ae. albopictus using OW, OWAT and SIG (respectively maps a, b, and c), projected using CanRCM4 model output as an illustration. The colour scale below each map shows the value for each indicator, and for SIG the cut off at 66.69% and 64.64% is indicated by arrows. The left hand column shows projections for 2011–2040 and the middle and right hand columns shows projections for 2041–2070 using, respectively, emissions scenarios provided by Representative Concentration Pathways RCP4.5 and RCP8.5. For the OW maps, climate of low suitability for Ae. albopictus is indicated by both yellow areas (where T_Jan is below 0°C and P_ann is below 500 mm) and white areas (where either T_Jan is below 0°C or P_ann is below 500 mm).
