Global climate and the destiny of sub-Saharian region

In the framework of global climate, Africa and in particular its sub-Saharian region, also known as Sahel, showa high vulnerability to climatic changes, and their consequences in terms of impacts are very strong. Here I will describe the present climate and its changes in the recent decades, initially at global scale and then in more details for Africa and Sahel. The problem of attribution will also be dealt with, in order to understand which factors are the main causes of the recent global warming. Once discovered that the human influences are the fundamental drivers for the climatic changes of the last decades, the common and differentiated responsabilities are examined. The final result shows that the sub-Saharian region is influenced by a climate change induced by human activities in developed countries, thus triggering an exacerbation of global inequality.
