**Abstract**

Hundreds of millions of urban dwellers in low- and middle-income nations are at risk as 4-5 of the global weather-driven disasters experienced are consequent of a changing climate. Studies have shown that residents in least developed countries have ten times more chances of being affected by these climate disasters than those in wealthy countries. Further, critical views have it, that it would take over 100years for lower income countries to attain the resiliency of developed countries. Unfortunately, global South is surrounded by a myriad of socio-economic and environmental factors limiting their fight against climate crisis. It is this germane reality that provoked the cause of this review. Hence, this paper reviewed the developing world's contribution to global warming and the resulting consequences of climate change with focus on Nigeria. This purposive approach adopted an analysis of secondary data related to climate information. The findings from the paper affirmed that impacts of climate change in developing countries include loss in agriculture/forestry resources, water shortage, food insecurity, biodiversity loss, health risks among others. Finally, it identified the major factors that exacerbate climate crisis, the human actions that trigger global warming and adaptive and mitigation approaches to minimize climate change related disasters.
