World’s global climate has been changing for many decades now. Natural events and human activities are the major contributors of climate change. The impacts are manifest through the adverse effects posed on environmental temperature rise, extinction of wild animals, status change in water resources availability, agriculture, vegetation, air quality and sea level. These are critically influenced by climate change and variability. Many studies by the Intergovernmental Panel on Climate Change (IPCC) suggest a discernible human influence on global climate change. While recent studies showed that human activities play a leading role in increasing climate change impacts. The projected results of these changes include flooding, damage to crops, soil erosion, adverse effects on surface and groundwater quality, water scarcity, water contamination, disease outbreak, loss of properties, disruption of the settlement, and other socio-economic challenges. In this paper the causes of climate change, the impacts on humanity and the remedies are discussed
