Global Warming is caused by the increase in the greenhouse effect, resulting in a raised average earth’s temperature. The main causes of global warming are the release of toxic and harmful greenhouse gases, like carbon dioxide and sulfur dioxide due to the burning of fossil fuel and industrial activities. Effects of global warming include incessant rain, unexpected climatic changes, rise in oceanic temperature, depletion in flora and fauna, melting of glaciers and floods, etc.
Essay on the Causes and Effects of Global Warming
Essay 1 (250 words)
An increase in environmental temperature and climate change has become very clear over the last 50 years because of the increasing level of greenhouse gas concentration (like water vapor, CO2, methane, ozone, sulfur and nitrogen gases, etc) in the atmosphere. Such as greenhouse gases contribute to an increase in the greenhouse effect.
The major cause of increasing greenhouse gas in the environment is the burning of fossil fuels which emit carbon dioxide and heat the atmosphere. Such greenhouse gases have the capacity to absorb more heat from the sun, heat from electricity used by human beings in many ways which in turn warm the whole atmosphere of this planet. The effects caused by greenhouse gases (water vapor, CO2, methane, ozone, nitrous oxide, hydrofluorocarbons, sulfur hexafluoride, per fluorocarbons, chlorofluorocarbons, etc) are called the greenhouse effect.
Heating of the environment increases atmospheric temperature (by 3° to 5° C by the year 2100), increases sea level (by 25 meters by the year 2100) and heat, melts glaciers, increases health disorders, changes climate, changes weather, increases annual power of hurricanes, calls natural disasters (floods, heatwaves, droughts, tornadoes), lowers down amount and quality of agricultural yields, enhances glacial retreat, reduces summer stream flows, extinctions of various important plants and animals species and so many.
There are some other dangerous effects of global warming which continuously affect the lives of human beings, plants, and animals. Global warming needs to be solved urgently by the active effort of each and every human being living on this planet.

Scientists and economists of many countries are working regularly in the field of global warming for many decades in order to figure out causes, effects, prevention measures, and solutions to it. In the last few decades, a huge level of change in the climate and weather has been seen clearly. It has disturbed the natural cycles and ecological balance in the atmosphere.
The most important cause of increasing global warming is the effect of greenhouse gases which are emitted by human activities. In order to work together and solve this issue by the global effort, there is a group of scientists formed by the United Nations (Intergovernmental Panel on Climate Change or IPCC). This group works together to research the various causes, dangerous effects, effective prevention measures, and effective solutions.
According to the research and report of various highly skilled scientists, it is noted that the ever-increasing level of several greenhouse gases is highly responsible for the warming of the atmosphere. Combustion of fossil fuels by various means such as automobiles, cars, factories, electricity use, etc are responsible for emitting various greenhouse gases like carbon dioxide, gases of sulfur and nitrogen, etc. Other contributors to the greenhouse effect are methane (released by means of landfills, agriculture, digestive systems of grazing animals), nitrous oxide from various toxic fertilizers, gases released by means of refrigeration and industrial processes, loss of forests, etc.
The release of various toxic greenhouse gases in the atmosphere is increasing the atmospheric temperature as they have heat-trapping abilities.
Methane gas molecules (20 times) and Nitrous oxide (300 times) have more ability to trap heat than CO2. In many countries, the use of chlorofluorocarbons has been banned because they also have the ability to degrade the ozone layer (a protective layer in the atmosphere) as well as high potential to trap heat thousands of times more than CO2. Other causes of global warming are deforestation which increases the CO2 level, decreases oxygen level, drought disturbs the ecological balance, changes climate and changes weather patterns.

Global warming is increasing day by day because of the continuous increase in the levels of greenhouse gasses. Such gases have a tendency to trap heat from many sources like sun, electricity, burning coal, burning fuels, etc and prevent them to escape back to the atmosphere. Thus, the collective effect of all the greenhouse gases increases the temperature on the earth and gives rise to many dangerous problems. Earlier, the earth was so cool and every natural cycle was going timely however nowadays lots of dramatic fluctuations in the weather, climate, temperature, health, etc takes place. A vast increase in the temperature, sea level, and weather patterns has been seen clearly in a few last decades.
All the changes because of the ever-increasing global warming are not a coincidence however it is caused by human activities and technological advancement. A little fluctuation in the level of atmospheric carbon dioxide may cause a high level significant effect on the global temperature. The continuous rise in the percentage of atmospheric carbon dioxide is alarming us by its dangerous effects however we are still ignoring. Increasing the need for fossil fuels (such as coal, oil, and gasoline) by the people of industrial civilization is giving the opportunity to rise in carbon dioxide emissions.
Deforestation is also causing an increase in carbon dioxide through a decreasing number of plants and exposing the soil to the sunlight. Trees are the best source to absorb CO2 from the atmosphere however what happens if we finish the main source of reducing CO2 level. Our mal practices just to live a luxurious life on a daily basis are hugely altering the environment as well as endangering the lives of people in return. A little rise in the level of greenhouse gases may hugely affect global warming.
The use of a chemical called chlorofluorocarbon (CFC) in the refrigerators, aerosol spray propellants are continuously damaging the ozone layer thus increasing the chance of heat to remain on the earth by preventing them to escape back out to the environmental surface. Destruction of the ozone layer increases the incidence of many health disorders and diseases such as skin cancer, respiratory disease, low immunity problems, etc. Global warming is damaging seasonal crops and marine food channel web, etc. It has affected the weather patterns (summer season has increased and the winter season has decreased) and climate because of the increasing temperature and heat of the earth’s atmosphere.
