Climate change and related challenges are affecting all over the world, particularly, African's 2030 path of sustainable development, especially in the desert regions, which include the most vulnerable and vulnerable systems. Climate changes are a natural phenomenon that occurs every several millennia, but increased last years as a result of human activity. It transcends the geographical boundaries of countries and poses a global threat. The steady increase in global surface air temperatures has been confirmed (0.3 and 0.6 oc) over the past 100 years. Any disruption of the Earth's ecosystem in general, increasing average atmospheric temperature, melting of the poles, inundation of island States and deltas, disruption of rainfall patterns, negative impacts on agricultural land productivity, water needs, public health and transmission of epidemic diseases. This review light on scientific concept of climate changes, climate change risks, climate worming and human footprint. Moreover, this review aims to discuss the historical development of international agreements, treaties and protocols that discussed addressing climate change and its current and future effects. Moreover, this review aims to discuss the historical development of international agreements, treaties and protocols that discussed addressing climate change and its current and future effects. Briefly, it summarizes what will happen to the blue planet if the reasons of climate changes continue?
