All these changes may become more frequent in the future decades and hugely challenge the society and environment. In the few past centuries, human activities have increased the release of large amounts of carbon dioxide including other greenhouse gases in the atmosphere. Most of the green house gases come from burning fossil fuels which work as blanket around the earth and trap all the energy and heat available in the atmosphere and thus warm the earth surface.
This effect is called as the greenhouse effect which triggers climate to change to the huge level and result in dangerous effects to the lives and ecosystems. Such a warmer climate affects the availability of natural water supplies, crop production, agriculture, natural environment, safety, security, etc. Such huge climate changes are unavoidable however cannot be stopped at once. Global warming has really affected and forced the climate to change over the last century throughout the world.
Some of the green house gases having more influence on the climate are CO2, water vapour, dinitrogen-oxide, and methane. According to the research, it has been recorded that almost 30 percent of the heat by incoming sunlight gets reflected back to the space through clouds and ice but because of global warming ice are melting. It means there are no left sources to send heat back to the space and all are getting collected in the earth atmosphere and affecting the climate. Every one of us is feeling very clearly from the short-term changes in the seasonal patterns of temperature, drought, rainfall without season, changing weather patterns, etc to the long-term changes affecting the entire earth.
Climate is a long-term weather trend affecting human lives positively or negatively. Climate change is the long term variations in the weather patterns.
Climate itself adjusts time to time however going at wrong path since many years because of regular loss of huge ice sheets. Earlier the earth atmosphere was covered with ice sheets which were able to make the earth atmosphere cool by preventing earth from heat and sending back extra heat out of the space from the earth. Climate has changed from cooler to warmer over the last two million years in the cyclical manner. Sun is the ultimate source of heat energy which fuelling the weather systems after reaching to the earth.
Earlier the harsh and extended bitter cold season was called as the little ice age which was due to the huge level variations in the solar activity. Such a huge variations in the climate may lead to the danger of the human lives. Earlier it was believed that shifts in the climate pattern from ice age to warmer periods was because of time however later it was imagined that it is due to regular melting of ice sheets of more than a kilometre in thickness.
Heat trapping nature of the green house gases contributes to the global warming. It has also been recorded in the northern hemisphere over the last century that there is decrease in snow cover by 10 percent, decrease in spring and summer sea-ice by percent, increases in rainfall and its intensity, huge level change in shifts of ice freezes and breaks up in the rivers and lakes.

Essay on Impact of Global Warming on Oceans. Please Help us to improve, Contact us. This essay on global warming needs to look at the causes of the problem. Greenhouse gasses such as carbon dioxide and methane can cause the atmosphere to build up, leading to solar radiation becoming trapped within the earth like within a greenhouse, hence the name.
The causes of global warming are both natural and anthropogenic but the anthropogenic influence is the most damaging. The phenomenon of global warming has been occurring naturally as a result of the natural rotation of the sun which changes the intensity of solar radiation hitting the earth, also natural processes such as volcanoes produce a large amount of Sulphur dioxide and other greenhouse gasses which can result in global warming too.
Once these greenhouse gasses become released, they can contribute to the buildup of the atmosphere and work to trap more solar radiation within the earth. Global warming is also largely a result of the release of methane from cracks in the earth, landfill sites and through natural gas leaks.
Methane has an effect on the atmosphere which is four times as bad for global warming as carbon dioxide. Cattle and other animals that produce methane can also contribute significantly to global warming, much of this has been a problem because of human animal farming which produces hundreds of cattle for the meat industry. The reason as to why global warming is such an issue today is because of the problem that humans are creating with anthropogenic contributions to greenhouse gasses.
Many of the practices that humans employ create enormous amounts of greenhouse gasses to be released and this has been well documented to be significantly harming the earth.
Modernity, modern technology and new lifestyles have resulted in human activities that produce a lot of greenhouse gasses such as deforestation, the combustion of fossil fuels, industrial action and farming animals. The growing rise of industry around the world and the rise of consumerism has resulted in the production of many goods, all using fossil fuels either directly or indirectly. Consider the example of something trivial a mobile phone — creating something like this will lead to a large amount of components that need to be made using fossil fuels.
Even if we want goods that have been grown on trees in our homes, they will need to be transported somewhere by transport that uses fossil fuels. Mining causes methane and natural gas to escape from where it is trapped below the earth. Shockingly, many energy companies around the world that drill for new fossil fuels such as oil can actually end up burning all the natural gas off in the process rather than storing it because it is not economically viable to do so.
This creates huge problems as there is a limited supply of natural gas and fossil fuels around the world. Deforestation is one of the biggest causes of global warming. Not only are trees cut down to make goods that need to be transported using fossil fuels, the removal of trees leads to a net loss of photosynthesis which is carried out by plants to make food. In this process, carbon dioxide can be absorbed and turned into oxygen, making food for the plants and cleaning the atmosphere as a result.
Polar ice caps can melt, there will be widespread flooding all over the world, there will be an increase in the frequency and intensity of harmful natural disasters and the consequences to the economy will be detrimental to societal progress. The melting of polar ice caps poses one of the biggest problems for human society. In the same way, glaciers will also melt and create problems on land.
According to scientific research, if all the snow and ice were to melt today, this would result in a raised sea level of over feet worldwide and would be instantly detrimental to many low lying areas such as the Netherlands and other low lying islands around the world.
It is the tragic case that most of the countries and areas that will be affected directly are often the ones that contribute the least to global warming. As global warming occurs, biodiversity all over the world will suffer. Food sources will be compromised, e. Natural disasters such as hurricanes will be of greater occurrence and this will cause an increase in the economic effects.
Hurricane damage alone will result in billions of dollars worldwide needing to be spent to rebuild societies and provide relief. It will be difficult for people and societies to keep up and offer enough support if global warming is too big of a problem.
All natural disasters from tornadoes to droughts will all increase in intensity — one can only imagine what a hurricane twice as strong would do!
As a society, there are certainly many solutions to prevent global warming and reduce its harmful effects, yet it will be difficult to coordinate these efforts together. It could be a lot easier to live for many more years if we were to stop burning so many fossil fuels, yet the problem is the incentive for people to change their ways and adopt new practices, especially in the light of global capitalism and consumerism.
Any global warming essay ought to shed some light on the solutions we can achieve. There are small choices that we can change about ourselves, for instance diving hybrid cars that reduce gasoline consumption. If a person needs to drive to work and pump their car many times a day, why do this when you can take public transport instead.
Both of these solutions are actually cost effective for consumers but the problem is that people like to have the goods they want e.
Recycling could also be adopted in the same way, producing less carbon dioxide as a result.
Global Warming and Climate Change Essay 4 ( words) Climatic changes have become more prominent now because of the global warming which is a global concern. Both are hot issues of the current time and it is the time to analyse causes and prevention methods to prevent the global warming.
Abrupt climate changes can occur when variable that change gradually push the Earth's system across some limit of instability. One of the known examples of this rapid change is the Younger Drays, which was a sudden interruption gradual global warming that began 12, years ago after the end of the last glaciations.
Keywords: climate change, global warming, greenhouse gases. Climate change in the world can be caused by various activities. When climate change occurs; temperatures can increase a dramatically. When temperature rises, . Global Warming Essay - Global Warming Two issues that worry many scientists are global warming and the greenhouse effect. The greenhouse effect is a natural process that keeps the earth at temperatures that are livable. What does the greenhouse effect have to do with global warming.
When it comes to an argumentative essay on global warming, there are two most likely possibilities. You may have to produce evidence that the climate change does not pose any threat worth talking about and that all the fuss about it is pointless. Or, you will have to prove that the global warming is happening and presents a problem that we need to . Global Warming is Causing Climate Change Essay - Global warming is the increase in the earth’s atmospheric temperature. Naturally occurring gases such as carbon dioxide, methane, nitrous oxide, ozone and water vapor trap heat from the sun, preventing it from leaving the atmosphere.
