Figure 2. Predicted Ae. albopictus range expansion in the northeastern USA under two climate change scenarios.

(A) Moderate increase in CO2 emissions (B2 scenario). (B) Higher increases in CO₂ emissions (A2 scenario). Predicted present range based on 1950–2000 climate data. Three future time periods: 2020s (years 2010–2039), 2050s (years 2040–2069), and 2080s (years 2070–2099). Urban areas are indicated (2010 US Census Bureau).
