Ghana has achieved a meteorological milestone I never thought possible for West Africa. The Ghana Meteorological Agency (GMet) just launched a Climate Atlas that can accurately project weather patterns for the next 50 to 100 years — something the country has never had before.
Dr. Eric Asuman, Director-General of GMet, revealed this breakthrough capability during a courtesy call on April 9 at the Nana Bosoma Royal Palace in Sunyani. He was addressing the Sunyanimanhene, Odeefour Ogyeamansan Boahen Korkor II, when he described the Atlas as an interactive national climate service platform.
Danish Partnership Powers Advanced Forecasting
What particularly notable about this project is the international collaboration behind it. The Atlas was developed in partnership with the Danish Meteorological Institute (DMI) and uses high-resolution projections at approximately a 4-kilometre scale.
GMet formally launched the platform in Accra on March 25, 2026, with support from the Danish Embassy in Ghana. The system combines Ghana's historical weather data with advanced regional and global climate models.
Alarming Poverty Predictions
The Atlas projects climate trends across three critical parameters: temperature, rainfall, and sea level rise. Dr. Ignatius Kweku Williams, Deputy Director-General in charge of Operations at GMet, delivered a stark warning at the launch.
Without urgent adaptation measures, up to one million Ghanaians could be pushed into poverty by 2050.
The projections show that the most intense warming will occur during the December to February period. Northern Ghana emerges as a particular hotspot with the highest temperature increases expected.
Government Calls for Widespread Adoption
Minister for Communication, Digital Technology and Innovations, Samuel Nartey George, positioned the Atlas as essential infrastructure for national planning. He called the tool a "scientific compass" at the launch event.
George urged all Ministries, Departments and Agencies, as well as Metropolitan, Municipal and District Assemblies to actively use the Atlas. His vision is for the platform to inform policy formulation, infrastructure design, and local development planning.
Rural Communities Need Access
During the Sunyani visit, the Sunyanimanhene welcomed the GMet delegation but raised an important concern. He urged the agency to extend its outreach to rural communities, noting that farmers in those areas depend heavily on local information centres for weather data.
Dr. Asuman emphasized that GMet's core mandate remains providing seasonal forecasts to support agriculture, aviation, and the general public. The Climate Atlas significantly strengthens that capacity by giving planners, engineers, and farmers the tools for evidence-based, long-term decision making.
This development positions Ghana ahead of many African nations in climate preparedness. As we face increasing technological solutions for climate challenges, the Atlas represents a critical step toward data-driven adaptation strategies that could save lives and livelihoods across West Africa.
