FIGURE 1——A comparison of regional estimated 1990s summer heat-related deaths versus mortality projected for each future decade, including both A2 and B2 scenarios for 2050s, and both acclimatized and nonacclimatized approaches: New York City metropolitan region.
Note. A2 scenario assumed rapid human population growth, relatively weak environmental concerns, and a lack of aggressive greenhouse gas regulations. B2 scenario assumed more-moderate population growth and increased concerns about environmental sustainability, with more aggressive greenhouse gas regulations, compared with A2.
