<< The physical hazards posed by climate change have manifest humanitarian impacts. For example, in scenario-based analysis for Race to Resilience, a campaign led by the UN High-Level Climate Champions, McKinsey found that in a 2.0°C world, roughly a billion more people would be exposed to climate hazards than in a 1.5°C world. In a scenario where 1.5°C of warming occurs by 2030, almost half the world’s population could be exposed to a climate hazard related to heat stress, drought, flood, or water stress. And compared with high-income nations, lower-income countries have larger shares of the population that are likely to be exposed to at least one climate hazard. >>
