Unless emissions of these gases are controlled we could face sudden and rapid climate changes including an increase in temperature and changes in weather patterns. These changes, in turn, would bring about sea level rise, flooding of low lying areas and destruction of manmade and natural systems. Agriculture could be disrupted and shift geographically. Other effects will include destruction of habitat and of species that cannot adapt quickly enough, stress on water resources and economic disruption. Fossil fuels such as coal, oil and natural gas are consumed by cars, industry, power plants and for commercial and residential uses.
Carbon dioxide is released in deforestation by burning or cutting.
After deforestation, carbon that is stored in the soil continues to be released for many years. CFCs are man-made chemicals used as refrigerants, solvents and blowing agents. Methane, or natural gas, escapes into the atmosphere during its transport, in the production of all fossil fuels and from landfills. It also is produced by cows and sheep and in rice cultivation. It comes from fertilizers and burning of wood and fossil fuels.
