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."

What hams working QRP at higher frequencies love: #ducting!

"...we show that at the time of the missile launch the prevailing weather conditions allowed a ground-based radar to detect targets far beyond the normal radar horizon through anomalous propagation conditions. During such conditions, the atmospheric index of refraction decreases rapidly with height, making electromagnetic radiation bend downward to, partly or fully, compensate the curvature of the Earth."
