Study Reveals 4 Billion People Experienced Extreme Heat Due to Climate Change
A new report indicates that half the world's population faced extreme heat, leading to health crises and agricultural damage, driven by climate change.
Overview
A recent study reveals that approximately 4 billion people, or half the global population, experienced an additional month of extreme heat from May 2024 to May 2025 due to human-caused climate change. This extreme heat resulted in significant health issues, crop losses, and strained energy and healthcare systems. The report highlights that heat waves are often underreported as silent killers, disproportionately affecting low-income and vulnerable communities. Experts emphasize the urgent need for improved heat response strategies and the phasing out of fossil fuels to mitigate future heat events.

The increase in extreme heat days has affected all 195 countries and territories analyzed, but particularly impacts vulnerable populations—including those in small island and developing states—who are considered on the frontlines of climate change. The countries with the highest number of dangerous heat days are overwhelmingly these groups.
Human-caused climate change has at least doubled the number of days with extreme heat across 195 countries and territories compared to a world without climate change. In the past year, climate change added an extra month of extreme heat for 4 billion people[1].
Extreme heat causes significant health crises, including increased mortality and disease, especially among vulnerable populations. Economically, it results in productivity losses, agricultural damage, and strained energy and healthcare systems. Projections indicate annual productivity losses could reach $2.4 trillion by 2030 due to extreme heat.
Experts recommend improved early-warning systems, heat action plans, and long-term strategies for heat events. They also emphasize the urgent need to phase out fossil fuels and transition to renewable energy to mitigate future heat events and protect vulnerable communities.
Extreme heat events have a disproportionate impact on low-income and vulnerable communities, who often lack access to cooling systems, green spaces, and healthcare. These groups are also more likely to work outdoors and live in areas with poor infrastructure, making them highly susceptible to heat-related health crises and displacement.
