In practically all countries, the combination of industrialization and accelerated urbanization has adversely affected numerous environmental values, including our essential ecosystems, the variability of regional climates, and the range of global biodiversity. The difficulties which arise from the rapid changes we experience are the origin of the many problems we encounter in our daily lives. The problems are fundamentally tied to the swift pace of digitalization and the inability of infrastructure to accommodate the immense amount of data needing processing and analysis. Inadequate or erroneous information from the IoT detection layer results in weather forecast reports losing their accuracy and trustworthiness, which, in turn, disrupts activities based on them. The intricate art of weather forecasting requires the meticulous observation and processing of massive datasets. The difficulties in achieving accurate and dependable forecasts are exacerbated by the intersecting forces of rapid urbanization, abrupt climate shifts, and widespread digitization. The interplay of intensifying data density, rapid urbanization, and digitalization makes it difficult to produce precise and trustworthy forecasts.
