*Climate change is a health crisis in Africa.The World Bank's 2024 Cost of Inaction Report* warns that rising temperatures are driving infectious diseases, worsening air pollution, and disrupting food and water security. By 2050, climate-related health shocks could cost billions, pushing over 100 million Africans into extreme poverty. As *FAMSA Climate & Health TWG*, we urge urgent action—strengthening healthcare infrastructure, investing in early warning systems, accelerating clean energy transitions, and supporting nutrition-sensitive interventions. *Health is the human face of climate change—the cost of inaction is too great to ignore.* #climatehealthafrica #actonclimate #healthforall #famsaclimatehealth #costofinaction
