The purpose of this research is to apply differential equations to predict future global cooling conditions. This can be done because the structure of the sun's layers is not static but is a dynamic both layers, depth, and interplanetary space dynamics. Thus, the dynamics of the sun will cause changes in the Earth's climate and climate. Sunspot data was obtained from LAPAN Watukosek Pasuruan. Magnetohydrodynamics (MHD) simulations are performed by combining partial differential equations involving basic physical parameters depending on space and time. The flux-corrected-transport algorithm is improvised using the MHD stability algorithm and integrated with Lagrangian. The results of this study are sunspot data analysis giving rough estimates for early warning, and the results of the new combination are able to provide a more accurate physics domain. Magnetohydrodynamic simulation results show that there may be a shortage of sunspots in the long run so that the earth will experience global cooling by 2075. © 2020 Author(s).
