Keywords:Global Simulation of Atmosphere, Atmospheric Temperature

Global warming is a critical issue that impacts the entire world, but finding solutions remains challenging, with the achievement of the Paris Agreement's goals appearing increasingly difficult. The primary causes of global warming are human activities and the resulting changes in natural environments, which are difficult to resolve rapidly and substantially due to their scale. In this context, various strategies to address global warming have been proposed. However, demonstrating their effectiveness on a global scale has proven difficult, often limited to localized reductions in energy consumption or CO? emissions.
Global atmospheric simulations have historically been used to study atmospheric structures in an academic context. By incorporating realistic physical processes and chemical reactions, these simulations represent actual atmospheric structures, enabling the analysis of various phenomena and dynamics. Although such simulations have contributed significantly, those conducted under hypothetical conditions have been relatively rare.
In this study, we propose an unconventional simulation approach by introducing hypothetical conditions, such as large-scale desert greening, to examine global atmospheric temperature changes. This numerical experiment explores extreme and large-scale conditions that cannot be tested in reality, allowing us to investigate innovative ideas and quantitatively evaluate their potential effects on reducing global warming. Specifically, we analyze the impact of deploying reflective sheets with unique albedo characteristics across desert regions and assess the resulting changes in atmospheric temperatures.
This study aims to shift the use of numerical simulations from traditional methodologies to a novel application as a virtual experimental environment. Through these investigations, we seek to provide a new perspective on addressing global warming and evaluating the feasibility of unconventional approaches.
