Global Warming Causes and Effects Essay 1 (100 words)
Global warming is a major concern nowadays because of the regular increasing temperature of the whole atmosphere. It is continuously becoming so powerful like a demon. There are many reasons for its ever increasing nature. The major cause of it is greenhouse gases like carbon dioxide, nitrous oxide, methane, chloro fluoro carbons, etc which are increasing in the environment mainly by the human activities. Some of are increasing number of automobiles, mushrooming industries, fossil fuels combustion, etc. Such activities emit more CO2 in the atmosphere which enhances global warmth of Earth. This increasing atmospheric temperature causes glaciers to melt, health disorders to occur and invites so many natural disasters.
Global Warming Causes and Effects Essay 2 (150 words)
As every one of us knows that couple of century, the climate on this planet was colder than now. And it is so surprising that even now it is not stable, it is increasing day by day. We are well aware and imagine its negative effects on our environment and body health. However, we are ignoring and continuing our bad habits which is flaming the global warming. Global warming is a constant process of increase in the annual temperature of whole planet. According to the statistics, it is recorded that in the last century the average increase in temperature is 0.7°C and sea level by 10 cm.
All the effects of the global warming (adverse effect on agriculture, floods, droughts, soil erosion, hurricanes, etc) are the huge indication of danger to our life. The main causes of the global warming are increasing human population, deforestation, increasing effects of green house gases, many careless human activities, etc.
Global Warming Causes and Effects Essay 3 (200 words)
There are many causes of the global warming which affects human lives and health in many aspects. The main cause of global warming is the human beings careless activities. Ever increasing human population are demanding more resources to live easy and healthy life such as land to live and crop cultivation, technological growth for comfort and deal with increasing temperature of atmosphere, etc. Fossil fuels burning for many reasons are highly responsible to increase global warming. People are realizing well the increase in environmental warmth however never mind their activities which are stimulating the global warming to increase. Continuously they are wasting natural resources and polluting the air, water and soil.
Increasing inventions of the technologies such as refrigerator, AC, car/automobiles, electric machines, oven, microwave, washing machine, etc because of the increasing need of human beings for technologies in order to make their life, easy and luxurious. All such resources ultimately contribute to the global warming. Burning fossil fuels in the automobiles emits various green house gases which get collected in the atmosphere and force it to heat. Increasing need of land by human being results deforestation which contributes to increase in CO2 and decrease in oxygen. It affects the human health, life style, calls diseases, calls natural disasters like hurricanes, heat waves, drought, climate change and so many.

Increase in environmental temperature and climate change has become very clear over the last 50 years because of increasing level of greenhouse gases concentration (like water vapour, CO2, methane, ozone, sulphur and nitrogen gases, etc ) in the atmosphere. Such as greenhouse gases contribute to increase in the greenhouse effect. The major cause of increasing greenhouse gas in the environment is burning of fossil fuels which emit carbon dioxide and heat the atmosphere. Such green house gases have capacity to absorb more heat from 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 the greenhouse gases (water vapour, CO2, methane, ozone, nitrous oxide, hydro fluorocarbons, sulphur hexafluoride, per fluorocarbons, chlorofluorocarbons, etc) are called as the green house effect.
Heating of the environment increases atmospheric temperature (by 3° to 5° C by the year 2100), increases sea level (by 25 meter by year 2100) and heat, melts glaciers, increases health disorders, changes climate, changes weather, increases annual power of hurricanes, calls natural disasters (floods, heat waves, 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 the global warming which continuously affects 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.
Global Warming Causes and Effects Essay 5 (300 words)
Scientists and economists of many countries are working regularly in the field of global warming from many decades in order to figure out causes, effects, preventions measures, and solutions of 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 ever increasing level of several greenhouse gases are highly responsible for warming of atmosphere. Combustion of fossil fuels by various means such as automobiles, cars, factories, electricity use, etc are responsible for emitting various green house gases like carbon dioxide, gases of sulphur and nitrogen, etc. Other contributors of the green house 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 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 is deforestation which increases CO2 level, decreases oxygen level, drought, disturbs ecological balance, changes climate and changes weather patterns.
Global Warming Causes and Effects Essay 6 (400 words)
Global warming is increasing day by day because of the continuous increase in the levels of greenhouse gasses. Such gases have 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 green house gases increases temperature on the earth and gives rise to many dangerous problems. Earlier, the earth was so cool and every natural cycles were 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 few last decades.
All the changes because of the ever increasing global warming are not a coincidence however it is caused by the human activities and technological advancement. A little fluctuation in the level atmospheric carbon dioxide may cause 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 need of 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 increase in the carbon dioxide through decreasing number of plants and exposing soil to the sunlight. Trees are best source to absorb CO2 from the atmosphere however what happen if we finish the main source of reducing CO2 level. Our mal practices just to live luxurious life on daily basis are hugely altering the environment as well as endangering the lives of people in return. A little rise in the level of green house gases may hugely affect the 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 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 winter season has decreased) and climate because of the increasing temperature and heat of the earth atmosphere.

Global warming is an increase in the average temperature of the earth’s temperature, especially a sustained change sufficient to cause climate change. The average facade temperature of the globe has increased more than degree since 1900 and the speed of warming has been almost three folds the century long average since 1970.
This increase in earth’s average temperature is called Global warming. More or less all specialists studying the climate record of the earth have the same opinion now that human actions, mainly the discharge of green house gases from smokestacks, vehicles, and burning forests, are perhaps the leading power driving the fashion.
The gases append to the planet’s normal greenhouse effect, permitting sunlight in, but stopping some of the ensuing heat from burning back to space.

Based on the study on past climate shifts, notes of current situations, and computer simulations, many climate scientists say that lacking of big curbs in greenhouse gas discharges, the 21st century might see temperatures rise of about 3 to 8 degrees, climate patterns piercingly shift, ice sheets contract and seas rise several feet.
With the probable exemption of one more world war, a huge asteroid, a fatal plague, or global warming may be the only worst dangers to our planet earth.
Global Warming Causes
The major cause of global warming is the release of green house gases like carbon dioxide, methane, nitrous oxide etc. into the atmosphere. The major source of carbon dioxide is the power plants. These power plants emit large amounts of carbon dioxide produced from burning of fossil fuels for the purpose of electricity generation.
About twenty percent of carbon dioxide emitted in the atmosphere comes from burning of gasoline in the engines of the vehicles. Buildings, both commercial and residential represent a larger source of global warming pollution than cars and trucks.
Building of these structures require a lot of fuel to be burnt which emits a large amount of carbon dioxide in the atmosphere. Methane is more than 20 times as effectual as C02 at entrapping heat in the atmosphere. Methane is obtained from resources such as rice paddies, bovine flatulence, bacteria in bogs and fossil fuel manufacture. The main sources of nitrous oxide include nylon and nitric acid production, cars with catalytic converters, and the use of fertilisers in agriculture and the burning of organic matter.
Another cause of global warming is deforestation that is caused by cutting and burning of forests for the purpose of residence and industrialisation.
Scientists all over the world are making predictions about the ill effects of Global warming and connecting some of the events that have taken place in the past few decades as an alarm of global warming. The effect of global warming is increasing the average temperature of the earth.
A rise in earth’s temperatures can in turn cause to other alterations in the ecology, including an increasing sea level and modifying the quantity and pattern of rainfall. These modifications may boost the occurrence and concentration of severe climate events, such as floods, famines, heat waves, tornados, and twisters.
Other consequences may comprise of higher or lower agricultural outputs, glacier melting, lesser summer stream flows, genus extinctions and rise in the ranges of disease vectors. As an effect of global warming, many species of birds and animals have already become extinct. As an effect of global warming various new diseases have emerged lately.
It is expected that many species will die off or become extinct due to the increase in the temperatures of the water, whereas various other species, which prefer warmer waters, will increase tremendously Perhaps the most disturbing changes are expected in the coral reefs that are expected to die off as an effect of global warming.
The global warming is expected to cause irreversible changes in the ecosystem and the behaviour of animals. Birds are a species that will be affected by a change in the climate. Global warming might result in birds finding a more permanent home in northern areas in the Northern Hemisphere.
The scientists tell us that the tundra is in danger of melting due to an amount of extra global warming pollution that is equivalent to the net amount that is previously in the earth’s/ atmosphere. Likewise, earlier one more team of scientists reported that in a single year Greenland witnessed 32 glacial earthquakes between 4.6 and 5.1 on the Richter scale.
This is a disturbing sign and points that a huge destabilisation that may now be in progress deep within the second biggest growth of ice on the planet. This ice would be enough to raise sea level 20 feet worldwide if it broke up and slipped into the sea.
Each day passing brings yet new proof that we are now in front of a global emergency, a climate emergency that needs instant action to shrilly decrease carbon dioxide emissions worldwide in order to turn down the earth’s rising temperatures and avoid any calamity.
It is not easy to attach any particular event to global warming, but studies prove the fact that human activities are increasing the earth’s temperature.
Even though most predictions focus on the epoch up to 2100, even if no further greenhouse gases were discharged after this date, global warming and sea level would be likely to go on to rise for more than a millennium, since carbon dioxide has a long average atmospheric life span.
Many efforts are being made by various nations to cut down the rate of global warming. One such effort is the Kyoto agreement that has been made between various nations to reduce the emissions of various green house gases. Also, many non profit organisations are working for the cause.
A1 Gore was one of the foremost U.S. politicians to heave an alarm about the hazards of global warming. He has produced a significantly acclaimed documentary movie called “An Inconvenient Truth” and has written a book that archives his advice that Earth is dashing toward an immensely warmer future.
A1 Gore, has given various speeches to raise an awareness of global warming. He has warned people about the ill effects of Global warming and its remedies.
The future of emissions damage depends on several factors, demographics, economics, technology, policies and institutional developments. Future predictions do not look good for this planet if nothing is done soon.
