Future scenarios for climate change and some of its repercussions on the world and Morocco, through international and national reports

Abstract

Climate change is one of the most significant existential challenges facing humanity in the 21st century. This is due to rising global temperatures, declining rainfall, and the rise of extreme weather events, necessitating a study of future scenarios. Due to the effects that will affect all systems. The research seeks to highlight the context of these scenarios, their expectations, and possible climate trajectories, and aims to identify some of their future implications for various systems. The problem will address future scenarios of climate change at the global and national levels and their effects. It will follow a methodology based on a dual approach (quantitative and qualitative), and on data from the reports of the Intergovernmental Panel on Climate Change, which based their results on global climate modeling data. We will also use the Geographic Information System (SIG) to highlight the field distributions of scenarios. The research showed that the climate of the world and Morocco will witness a significant trend towards further warming. Rainfall and wet days will decline, while the number of heat waves and the frequency of dry years will increase, with spatial variations. Morocco is perhaps one of the most prominent regions in the world most affected by these changes in its natural resources, economy, ecosystems, and human health.
