The interference of advanced telecommunications with major weather and climate forecasting: This is *not* a trade-off!

The wireless industry quickly agreed to 5G standards and started building out infrastructure, requiring more spectrum real estate to support the growing demand. This led to a campaign by the Federal Communications Commission (FCC) to. . .sell bands of frequencies between 24–25 GHz to companies invested in 5G technology.

Terrestrial radio systems emitting 5G signals into this defined spectrum range, so close to the bands allocated for weather sensing (23.8– 24GHz), are a formidable threat to weather forecast and warning services. This is due to the much louder nature of 5G waves compared to those emitted by the atmosphere, and the relatively quiet movements of water vapor molecules that satellites observe. According to federal agencies and meteorologists worldwide, if the 5G signal remains contained between 24–25 GHz, it can coexist alongside existing meteorological operations. However, if it becomes louder, it will bleed over into the weather sensing space, drowning out any noise—invaluable for climate models—emitted by water particles. . . .

A 5G station transmitting at nearly the same frequency as water vapor can be mistaken for actual moisture, leading to confusion and the misinterpretation of weather patterns. This interference is particularly concerning in high-band 5G frequencies, where signals closely overlap with those used for water vapor detection. High-band 5G operates at much higher frequencies, typically in the millimeter-wave range (24GHz to 40GHz), allowing for faster data speeds but also presenting challenges in signal propagation. These high frequencies are absorbed more readily by atmospheric gases, including water vapor, resulting in significant signal attenuation. Consequently, the potential for interference with weather sensing is heightened in high-band G due to the proximity of its frequencies to those critical for water vapor detection.

Of course, economists will insist this represents a trade-off. It is no such thing. At least, not as long as society mandates high reliability both in advanced telecommunications and in advanced forecasting of weather and climate.
