The links between climate, poverty and health are clear. The climate crisis is a health-risk multiplier. Extreme weather events are devastating health globally. By 2030, climate's negative health effects could drive 40M people into extreme poverty. With climate pressures putting a burden on already stressed health systems, the cost of inaction on lives and the planet is huge. The World Bank's climate and health initiative helps design country-tailored solutions and scale up investments to build climate-resilient health systems. Together we can build a healthier, more sustainable future for generations to come.
