A record-breaking 710,000 estimated deaths globally were attributed to heat in 2023, according to a report released on Wednesday by the Lancet Countdown in association with the World Health Organization.

Rising Climate Risks and Health Threats

For the first time, more than seven in 10 fatalities were linked to human-caused climate change. The findings indicate that heat-related deaths, drought, and other climate-related risks are increasing faster than a decade ago. Specifically, the global area impacted by extreme drought grew more than 700 percent faster than it did between 2006 and 2015, affecting 51.8 percent of land on earth for at least one month in 2025. Furthermore, the conditions suitable for dengue transmission by Aedes albopictus mosquitoes increased by 24 percent from 1981-90 to 2016-25, while suitability for Aedes aegypti mosquitoes rose by seven percent. Meanwhile, the world’s 100 largest oil and gas companies plan to produce 150 percent more fossil fuels by 2040 than is compatible with keeping warming to 1.5 degrees Celsius above pre-industrial averages.

Progress in Clean Energy and Adaptation

Despite these worsening threats, the report highlights positive developments, pointing to a record 2.1 trillion dollar global investment in clean energy last year. Many nations lowering fossil fuel-related air pollution are protecting thousands of individuals from premature deaths annually. Additionally, around one in four countries now possess a national plan for adapting health services to climate change, rising from just 14 WHO Member States in 2015. Authors and researchers from around the world, led by University College London, maintain that these findings demand the formal recognition of climate change as a global health emergency ahead of the UN COP31 climate conference in Antalya, Türkiye.
