Quantifying the Impact of Climate Change on Human Health

The report projects that by 2050, climate change will cause 14.5 million additional deaths and $12.5 trillion in economic losses worldwide. It identifies floods as the highest acute risk for mortality and heat waves as the primary driver of economic loss. The analysis emphasizes that 79% of the health impact is driven by morbidity (long-term disabilities) rather than mortality. To address this, the report advocates for a 'resistance and recovery' framework for healthcare systems, supported by government incentives and private-sector innovation.

• By 2050, climate change is projected to cause 14.5 million additional deaths and $12.5 trillion in economic losses globally, with an additional $1.1 trillion in costs specifically for healthcare systems.
• Floods are identified as the greatest acute risk for climate-induced mortality, accounting for 8.5 million of the projected deaths by 2050.
• Heat waves are expected to cause the most significant economic damage, with an estimated $7.1 trillion loss by 2050 primarily due to productivity declines.
• The overall health impact of climate change is predominantly driven by morbidity (79%) rather than mortality (21%), highlighting a trend of long-term disabilities and health conditions.
• Climate change is expected to expand the geographical range of vector-borne diseases such as malaria, dengue, and Zika into moderate climate zones, including the United States and Europe, putting an additional 500 million people at risk by 2050.
• Developing regions will be disproportionately affected; Africa and the Middle East are projected to suffer a cumulative impact of 1.27 billion DALYs and $2.7 trillion in economic costs.
• Droughts are projected to cause 3.2 million deaths by 2050, with stunted development in children being the most significant health outcome, costing the health system $1.8 trillion.
• The report proposes a two-pillar framework for climate-resilient health systems: 'resistance' (preventing or delaying impacts) and 'recovery' (stabilizing populations and treating long-term consequences).
• To encourage private sector investment in climate-health solutions, the report suggests four types of incentives: direct economic incentives, financial enablement, regulation, and awareness building.
