According to climate change scientists, the burning of fossil fuels (coal, oil, and the like) results in the releasing of carbon dioxide atoms into the atmosphere, which can cloud the atmosphere, obscuring sunlight, as well as deplete the ozone layer, resulting in an increase in global temperature. This change could potentially cause some cooler temperature-loving species to either migrate in search of cooler locations or possibly die out if they are unable to move (biosphere). It could also cause water levels in some areas to decrease due to evaporation, or increase due to the releasing of water into the oceans resulting from the melting of our polar ice caps (hydrosphere).
Hope that helped! =)
