🟢 Strong Evidence
Global average temperatures are likely to reach record levels within the next five years, according to the latest assessment from the World Meteorological Organization (WMO). The prediction underscores mounting concerns about climate change impacts on public health worldwide.
Key takeaways
- WMO forecasts record-breaking global temperatures in the next five years
- Climate change poses escalating risks to global health systems
- Extreme weather events linked to rising temperatures threaten vulnerable populations

Climate Change Accelerates Health Threats
The World Health Organization has identified climate change as one of the greatest threats to global health in the 21st century. Rising temperatures contribute to heat-related illness, expand disease vector ranges, and compromise food security.
Extreme heat events pose particular risks to vulnerable populations, including elderly individuals, children, and those with chronic medical conditions. The Centers for Disease Control and Prevention reports that heat-related deaths have increased significantly in recent decades.
Health Systems Under Pressure
Climate-related health impacts are straining healthcare systems worldwide. Heat waves increase emergency department visits and hospitalizations, while extreme weather events can damage healthcare infrastructure and disrupt medical supply chains.
The global health community recognizes the urgent need for climate-resilient health systems. Healthcare facilities must adapt to handle increased patient loads during extreme weather events while maintaining essential services.
Vulnerable Populations Face Greatest Risk
Climate change disproportionately affects marginalized communities with limited access to healthcare and cooling resources. The displacement of populations due to climate events creates additional health challenges, including infectious disease outbreaks and mental health impacts.
Urban heat islands particularly affect low-income communities, where access to air conditioning and green spaces may be limited. Public health officials emphasize the importance of targeted interventions to protect these vulnerable groups.
Climate change is fundamentally a health issue, with rising temperatures posing direct and indirect threats to human wellbeing across all populations.

What this means
Frequently asked questions
How does extreme heat affect human health?
Extreme heat can cause heat exhaustion, heat stroke, and exacerbate existing medical conditions like cardiovascular and respiratory diseases. It also affects medication efficacy and increases hospital admissions.
Which populations are most vulnerable to rising temperatures?
Elderly adults, young children, pregnant women, outdoor workers, and individuals with chronic conditions face the highest risks from extreme heat exposure.
What can healthcare systems do to prepare for climate change?
Systems can develop heat emergency protocols, strengthen infrastructure resilience, and implement early warning systems for extreme weather events.
The WMO’s temperature predictions highlight the urgent need for coordinated global action on climate change and health adaptation. As temperatures continue to rise, healthcare systems must evolve to protect populations from escalating climate-related health risks while addressing the root causes of global warming.
