Global warming occurs when the concentration of certain gases known as greenhouse gases, increases in the air, This was caused by human action, industrial activity, especially CO2 and chlorofluorocarbons. Which is mainly carbon dioxide, which is generally produced by the use of coal, petroleum, gas and deforestation and forest burning. Nitric acid is produced by vehicle and industrial emissions, while methane emissions caused by industrial and agricultural activities. Chlorofluorocarbons CFCs damage the ozone layer as well as greenhouse gases causing global warming, but now removed the Montreal Protocol. Carbon dioxide, chlorofluorocarbons, methane, nitrous oxide are polluting gases are accumulating in the atmosphere and trapping more heat from the sun. While the oceans and vegetation capture more CO2, its ability to be a “roof” is now redundant due to emissions. This means that every year, the cumulative total amount of greenhouse gases in the atmosphere increases thus accelerating global warming.

Throughout these hundred years the world’s energy consumption increased spectacularly. Approximately 70% of energy used by developed countries; and 78% of energy comes from fossil fuels. This creates an imbalance that leaves some regions impoverished and others reaping the benefits. Meanwhile, the amount of funding for renewable energy that can not be depleted (solar, wind, biomass, hydro, especially mini and micro hydro), which can reduce fossil fuel use, both in developed and developing countries remains extremely low, in comparison with the financial assistance and investments allocated to fossil fuels and nuclear energy. » Read more: What causes global warming?
