Ocean water contains a lot of carbon dioxide due to the ecosystem supported in the water (Haldar, 2011). Although it is not a primary cause, the high percentage of CO2 leads to global warming. The north and south poles of the earth are very cold. Due to the temperatures in these regions, frozen carbon has been accumulated over time. Any disturbances in this regions lead to melting of the permafrost and hence releasing the greenhouse gas into the atmosphere. Most of the frozen carbon is due to the carbon cycle and releasing of the gas causes atmospheric imbalance and hence global warming. Solar activities have changed, and the changes have influenced a change in the earth’s solar radiation levels.
Changes in solar radiation in turn lead to short term warming cycles (Haldar, 2011). Due to this, the sun has formed sunspots known as faculae that increase the radiations reaching the earth. The amount of water in the atmosphere has increased due to carbon dioxide-induced warming. The water vapor in the atmosphere in turn traps a lot of heat which causes global warming. Man-made causes of global warming Global warming is mainly caused by irresponsible human activities.
Some causes are not controllable while others are due to the ignorance of human beings. 80%of the causes of global warming fall under manmade causes. Man-made causes of global warming lead to an increase in greenhouse gases that in turn trap infra-red radiation that are emitted from the earth. Most parts of the world have industrialized and therefore burning of fuels to produce energy is the norm all over the world. Burning of fuels leads to the production of carbon dioxide that is the most significant cause of global warming (Haldar, 2011).
The carbon dioxide from burnt fuels increases the percentage of the total carbon dioxide present in the atmosphere. The high percentage of CO2 absorbs infrared energy that should have been released into space. The high energy requirements to meet the demands of industrial growth are another major cause of global warming. In the United States, 40% of all the carbon dioxide released into the atmosphere comes from electricity production (Maslin, 2007). Burning of coal is the major source of electricity, and it produces a lot of carbon dioxide that in turn causes global warming.
The number of automobiles has increased. The desire of people to drive their own cars has also increased and hence many people own and drive their cars. Burning of gasoline in cars leads to emission of carbon dioxide.
