WHO–WMO Accelerator Expands Global Efforts to Turn Climate Science into Life-Saving Health Action

Despite the availability of climate data, a key gap has been the translation of this information into health action — a gap the Accelerator seeks to close.

As climate change intensifies health risks worldwide, global agencies are accelerating efforts to transform climate science into actionable public health protection. The WHO–WMO Climate and Health Science and Services Accelerator is emerging as a key platform driving this transformation through stronger collaboration, innovation, and capacity building across sectors.

Spearheaded under the WHO–WMO Climate and Health Joint Programme, the Accelerator aims to ensure that climate services for health are not temporary interventions but become permanent, integrated components of national health systems. Its core focus is on enabling health authorities and meteorological services to work together more effectively — translating climate data into early warnings, preparedness strategies, and targeted responses that save lives.

Scaling Climate Services for Health

The initiative emphasizes the co-production and use of climate services, meaning that health and climate experts jointly design tools and systems that directly address real-world health risks — from heatwaves and air pollution to vector-borne diseases.

This approach ensures that climate intelligence is not just generated, but actively used to:

• Strengthen early warning systems

• Guide public health decision-making

• Improve emergency preparedness

• Protect vulnerable populations

Key Milestones Signal Global Momentum

In recent months, the Accelerator has achieved several significant milestones that highlight growing global momentum:

• South Asia Climate-Health Desk launched, providing region-specific climate and health intelligence to support decision-making

• Africa Climate-Health Desk established, hosted by the African Centre of Meteorological Applications for Development (ACMAD), to enhance continent-wide preparedness for heat and health risks

• Strengthened heat-health early warning systems, improving countries' ability to anticipate and respond to extreme heat events

• Creation of the South Asia Hub of the Global Heat Health Information Network (GHHIN), boosting regional coordination, knowledge sharing, and advocacy on heat-related health threats

These developments mark a shift from pilot initiatives to scalable, institutionalized systems that embed climate-health services into national and regional frameworks.

Addressing a Growing Global Health Threat

Climate change is increasingly recognized as a major public health challenge, contributing to:

• Rising heat-related illnesses and deaths

• Spread of infectious diseases

• Food and water insecurity

• Increased frequency of extreme weather events

Despite the availability of climate data, a key gap has been the translation of this information into health action — a gap the Accelerator seeks to close.

Building Long-Term, Resilient Systems

A central principle of the initiative is sustainability. Rather than short-term projects, the Accelerator promotes:

• Long-term institutional partnerships

• Capacity building for national agencies

• Integration of climate services into routine health planning

• Strengthened data sharing between sectors

This ensures that countries are better equipped not only to respond to immediate risks but also to build resilient health systems capable of adapting to future climate challenges.

From Data to Action

Experts stress that turning climate science into meaningful protection requires more than technology — it demands continuous collaboration, investment, and political commitment.

By linking meteorological data with public health systems, the Accelerator is helping countries move from reactive responses to proactive, preventive strategies, where early warnings translate into early action.

A Growing Global Network

The expansion of regional hubs and desks reflects a broader vision: creating a global network of climate-health services that are locally relevant but globally connected.

These efforts are expected to play a critical role in reducing climate-related health risks, particularly for vulnerable populations in low- and middle-income countries, where impacts are often most severe.

Looking Ahead

As climate threats intensify, initiatives like the WHO–WMO Accelerator are positioning climate services as a cornerstone of public health systems. The recent milestones demonstrate that progress is underway — but scaling these efforts globally will require sustained funding, stronger partnerships, and continued innovation.

Ultimately, the goal is clear: to ensure that climate knowledge translates into timely, effective action that protects lives and strengthens resilience worldwide.
