We're changing _everything_.

"Future projection indicates a consistent increase in surface refractivity across West Africa throughout the 21st century, with stronger amplification under the high – emission scenario. The largest increases occur along the humid coastal belt, reaching approximately +15 to +20 N-units by the late century, while the Sahel exhibits comparatively smaller changes. Relative changes show that refractivity increases by about 6-7% in the Equatorial Monsoon zone and 4-5% in the Tropical Savannah zone under SSP5-8.5. Scenarios divergence becomes pronounced after mid-century, highlighting the growing influence of emission pathways.

These changes are driven by enhanced atmospheric moisture and temperature increases associated with global warming. Th result demonstrate the importance of ensemble-based approaches for reducing model uncertainty and provide critical insight for climate-sensitive applications, such as radio wave propagation and telecommunication planning across West Africa."
