Global warming is defined as an increase in earth’s average atmosphere temperatures that cause corresponding changes in climate and that result from the greenhouse effect like carbon monoxide emission from burning of fossil fuels and methane gas.
In 2013, Intergovernmental Panel on Climate Change (IPCC) summarized that it’s likely the human influences such as burning of fossil fuels, farming and deforestation that has been cause of Global Warming. (Summary for Policymakers AR5 WG1 PDF P.4). However global warming is also caused by natural activities like natural rotation of the sun, carbon monoxide and volcanic eruptions.
Causes of Global Warming
Global warming happens due to the natural rotation of the sun that changes with intensity of sunlight. Another vital cause of global warming is volcanic eruption which releases carbon monoxide, once this greenhouse gas is released into the atmosphere the earth’s temperature increases trapping solar radiation into the earth.
Burning of fossil fuels such as coal to generate electricity leads to emission of greenhouse gases such as carbon monoxide into the atmosphere. Coal burning accounts for 93% of carbon monoxide emission thus a great contributor to global warming ( Michael,2005).This can be prevented by reducing the amount of electricity generated from coal.
Another cause of global warming is farming involving intensive cattle keeping that leads to emission of methane gas which traps the heat and prevent it from escaping into the atmosphere. This can be mitigated by use of different fertilizers and different stock feeds.
Deforestation. Plants regulate the climate since they absorb carbon monoxide from the air and release oxygen back to it therefore when vegetation is cleared, stored carbon is emitted back into the atmosphere as carbon monoxide causing global warming. This can be prevented by government initiating campaigns for tree planting through reforestation and afforestation.
Effects of global warming
If global warming continues several consequences are bound to happen including; polar ice caps melting leading to raise on sea levels since melting glaciers become oceans, species such as tropical frogs will lose their natural habitat due to climate change and occurrence of hurricanes that causes damage to houses and emergence of diseases that are very costly even to the government.
In conclusion global warming poses a serious threat to mankind, wildlife and ecosystem of the planet that needs both the intervention of government and individual to help curb it before it goes out of reach.
