Climate Risks in a Fragmented World 

Feature image: Comparison of global risks ranked by severity over the short term (next two years) and long term (next ten years), highlighting a shift from geopolitical and societal risks in the near term to environmental and climate related risks over the longer horizon. Extreme weather events, biodiversity loss, and critical changes to Earth systems dominate long-term risk rankings, underscoring climate change as the most severe systemic threat facing the global community. Credit: World Economic Forum, Global Risks Perception Survey 2025–2026. 

The Global Risks Report 2026, published by the World Economic Forum (WEF), underscores that climate change has become a central driver of global risk rather than a standalone environmental challenge. The report highlights how rising temperatures extreme weather events and ecosystem degradation are increasingly interacting with geopolitical economic and technological pressures amplifying vulnerabilities across societies and weakening the capacity for coordinated global response. 

Key Climate Related Findings 

• Climate change acts as a risk multiplier, interacting with leading short-term risks such as geoeconomic confrontation 18 percent and armed conflict 14 percent, and amplifying long-term instability 

• Extreme weather is a leading risk across time horizons, cited by 8 percent of respondents in the near term and ranking as the top global risk over the next decade, with growing impacts on infrastructure food systems and health 

• Environmental degradation and biodiversity loss are accelerating with long term consequences for human health and economic resilience 

• Climate impacts are increasingly intersecting with conflict and displacement, particularly in fragile and climate vulnerable regions 

• Unequal exposure to climate risks is deepening global inequality, placing disproportionate burdens on low income and climate vulnerable countries 

• Delayed climate action increases the likelihood of cascading risks, including food insecurity, water stress and energy system disruption 

• Geoeconomic fragmentation threatens climate cooperation, weakening coordinated mitigation and adaptation efforts 

• Climate misinformation and disinformation undermine public trust and delay effective climate policy responses 

• Rapid technological change presents both opportunities and risks for climate action, depending on governance and access 

• Failure to integrate climate risk into economic and security planning increases systemic vulnerability 

Climate Change as a Systemic Risk 

The report underscores that climate risks cannot be addressed in isolation. Weak global cooperation, rising geopolitical competition, and fragmented governance structures are reducing the capacity to respond effectively to climate change. Without stronger integration of climate science into decision making, climate impacts are likely to compound existing economic social and security challenges. 

Global Climate Implications 

• Increased frequency and severity of climate related disasters 

• Rising pressure on food water and energy systems 

• Greater risks to human health particularly from heat stress and air quality 

• Escalating displacement and migration driven by climate impacts 

• Reduced capacity for coordinated global climate action 

Urgent Climate Response Needed 

• Accelerate climate mitigation to limit further warming and systemic risk 

• Scale up climate adaptation and resilience especially in vulnerable regions 

• Rebuild international cooperation to address climate change as a shared global threat
