URGENT UPDATE: Experts are sounding the alarm as the dual threats of climate change and conflict are set to escalate health crises globally. A new report in The BMJ highlights alarming statistics that reveal the devastating interplay between these two factors, warning that “synergistic effects” could lead to unprecedented health outcomes.
From 1995 to 2015, more than 10 million child deaths were linked to conflict. Furthermore, women of reproductive age in high-intensity conflict areas faced mortality rates three times higher than their counterparts in peaceful regions. This stark data underscores the urgent need for immediate action.
The report also reveals that over 60,000 heat-related deaths were recorded in 32 European countries during the scorching summers of 2022 and 2024, with women being disproportionately affected. These figures exemplify the dire health risks posed by rising temperatures, demonstrating an immediate need for comprehensive climate strategies.
Beyond immediate fatalities, the report stresses that climate and conflict hazards are damaging health infrastructures and disrupting essential supply chains. These disruptions lead to increased undernutrition and the spread of infectious diseases, endangering communities worldwide.
Experts emphasize that climate action—both mitigation and adaptation—is critical. However, ongoing conflicts divert resources away from these vital efforts. Following Russia’s invasion of Ukraine, for instance, Ukraine’s climate mitigation investments saw a significant drop as funds were redirected to war and reconstruction efforts.
Moreover, military activities themselves are a major, yet underreported, source of greenhouse gas emissions, accounting for an estimated 5.5% of the global total, with the United States being the largest contributor. The report calls for urgent recognition of this connection to foster sustainable development and peace in a rapidly changing climate.
To combat these escalating challenges, decision-makers at all levels must understand the critical relationship between climate, health, and conflict. The experts advocate for scaling up climate action, particularly in fragile and conflict-affected states. One promising tool mentioned is the Climate Conflict Vulnerability Index, which identifies areas where climate and conflict hazards intersect with social vulnerabilities, including health.
The report concludes with a powerful message: “Only by integrating climate action with conflict prevention and peacebuilding can we disrupt the vicious cycle of escalating climate impacts, deteriorating health, and rising instability.” Strengthening health systems must be a central focus of these efforts to ensure a healthier, more resilient future.
As the world grapples with these complex challenges, immediate action is imperative. The health of millions hangs in the balance, and stakeholders globally are urged to prioritize climate resilience and conflict prevention strategies now more than ever.
