Climate change (CC) is leading to unprecedented changes to the whole Earth ecosystem, including the oceanic and atmospheric domains. In the last decade, some studies have analyzed the impact of CC on underwater acoustic communication systems. Conversely, very little work on the effects of CC on the performance of microwave-based technologies, such as radar and wireless telecommunication systems, has been carried out, mainly devoted to rainfall impact. Consequently, the potential effects of CC on such technologies remain rather unexplored. Indeed, it is expected that CC will lead to significant changes in the atmospheric structure and parameters, including the intensity and rate of anomalous conditions, such as atmospheric ducts. This work aims at trying to fill this gap and address the potential impact of expected changes in atmospheric ducts on electromagnetic (EM) propagation at microwaves. To …
