The study was carried out to create awareness of the destruction we can cause to ourselves as human beings, if we continue to contribute, by our actions to the natural causes of climate change. The problem is the visible destructions all over the world due to climate change;especially when the focus is on the areas of heavy pollutions, the changes in rain pattern, making farmers vulnerable. Increase in temperatures also lead to global warming. The type of research used is descriptive and that deals with qualitative approaches. Data collection involved both primary and secondary sources. The natural causes of climate change include volcanic activity, solar output, Forest Fires, Permafrost, Sunspots, Water Vapor, Man’s Best Friend. Those caused by human are burning of fossil fuels and the conversion of land from forestry to irresponsible agricultural practices. Gases emission from landfills;overpopulation;irresponsible mining;misapplication of fertilizers and other agrochemicals;meat consumption. Evidence of climate change includes change in rainfall pattern, increase in temperatures, extreme drought, change in harmattan pattern. Low production of fruits by trees in the wild;eroded arable lands;annual drying of dams that never dried in decades and also the shortening of lifespan of living things. Effects of climate change include desertification of the world’s arable land, persistent droughts, locally and abroad, unprecedented damage to infrastructure due to acid rain, volcanic eruption, earth quake, coastal erosion, unpredictable farming seasons, extinction threat on the wildlife, marine life extinction, flooding of coastal cities and island nations. Human being is a facilitator of the naturally occurring climate change. Those who mine natural resource without recourse to the laws of the land they occupy, should be dealt with legally.
