Global warming is a topic of discussion that many people can debate or try to avoid. It is often argued that the causes of global warming are either caused by humans, nature, or both. Some of these people don’t even have a clue about the impact they have on Earth and the ozone layer. Some people may not even know what causes global warming. If people don’t know how they are contributing to global warming, how are they going to contribute to stop it? Humans affect global warming by activities that range from driving to expanding their family. In this case, global warming’s effects are overwhelmingly connected to human activity. As the world evolves and new ideas are becoming a reality, humans have to make space to accommodate the changes. This causes people to constantly clear forests. The clearing of forests is one of the main causes of global warming. By removing forests, humans are taking away Earth’s ability to repair itself naturally. The more trees that are cut down, the more carbon dioxide there is to destruct Earth’s ozone layer. In turn, this cause …show more content…
Although, natural changes alone don’t explain the increase in the global climate. As David K.C. Jones would say, “…human influences are, for the most part, merely modifying the rates of change” (Jones 127). Some of the activities people do on a daily basis are creating a huge impact on the main causes of global warming. As the world is evolving, the possibilities of humans causing global warming are increasing. According to Dale Jamieson, “There is no way to assess accurately all the possible impacts [of global warming]” (Jamieson 144). Most likely there is always going to be something that causes global warming. With new data showing how different things humans do affect the global temperature, it is not just natural occurrences that cause global warming
The present climate change is mostly human induced; the increase in CO2 is mainly because of human activities. Activities like changes in land use pattern, deforestation, land clearing, agriculture, and other activities that have all led to a rise in the emission of carbon dioxide.
First, during the last few decades the Earth is experiencing greater rate of rising temperatures due to greenhouse gases that are being produced by human activities rather than because of environmental reasons, such as solar or volcanic activities. In 2006 the President of the National Academy of Sciences stated: “There is no doubt that the Earth is warming,” also he added that people are at least partly responsible for these changes in addition to regular factors (Cicerone, par.4). Natural factors have produced climate fluctuations on Earth for several million years. People have effected an atmosphere of the Earth just for nearly one hundred years, since Industrial Revolution has begun (Revkin 340). Of course, it is unfair to say that global warming is caused entirely by humans. For example, people can not have an impact on the position of Earth in relation to the sun, or on the galactic density, or such nature events as air emissions of volcanic gases. As a result of these environmental factors, Earth usually had higher rates of temperature fluctuations during the previous million years than it has in later centuries. On the other hand, people are responsible for the highest concentration of greenhouse gases during the last 650,000 years in the atmosphere due to industrial manufacturing, driven by the increase in consumer consumption (Lindsey, par.
Global warming is an issue we are all pretty familiar with. It is the climate change that we, humans, are responsible for. The warming of the earth’s atmosphere is caused by the fossil fuels we burn, clearing of forests, and the carbon dioxide and other harmful gases we release into the air (Cunningham, Cunningham, 2009). There are other harmful toxins we use such as pesticides that are supporting global warming. Some effects of global warming include: increase in weather catastrophes, melting glaciers, rising sea levels, and the impact on species could lead to extinction (Cunningham, Cunningham, 2009). “Many scientists regard anthropogenic global climate change to be the most i...
There are so many factors in today’s growing population and its action that contributes to the environment. With the rise in population there is also increase in the needs and demands resulting in more production of food and assets. Most of the actions of human lead to increased environment risks which in return will only effect the livings of this planet. Currently mostly all individuals have at least one form of vehicle for transportation. There is increased industrialization and requires a lot of energy which comes from fossil fuels as the need for oil increases to fuel large amounts of humans daily work and chores. The climate change is no mystery, it is known to be cause of various human actions trying to satisfy their needs while putting
Global warming has become on of the most controversial issues in the media today. While most of the Western world countries have generally accepted the premise that man's chemical emissions in the atmosphere can and are affected by the world’s climate patterns, in the United States, the issue has become so politicized with many republicans challenging the science behind the theory. Global warming is a greenhouse effect whereby gases are trapped on the earth’s surface causing it to heat up (Maslin 14). It is based on the worldwide temperature records that have been maintained by human beings through their activities since the 1880,s. In addition, global warming is not only caused by human activities only but also through climate changes in solar radiance. The problem is that, humans continue to contribute to the global warming phenomenon. All citizens should work in reducing human activities that cause global warming and also support the development of nuclear power. Scientists deem that, global warming is mainly caused by human activities which accelerate the natural process by creating greenhouse gases in the atmosphere. Human activities have become a great contribution to the greenhouse effect and this means that climate changes are inevitable. They further argue that, if these activities continue and are not reduced, it will lead to more trapping of energy radiated from the earth and this will likely lead to extreme weather and global warming. Global warming should be at reduced levels or else, it will be catastrophic.
On average millions of hectares of forests are destroyed each year resulting in severe consequences that will affect not only our lifestyle, but also all the animals with which we share our planet. Many species of animals and plants will become extinct and if we continue with the destruction of our forests, earth will be unable to sustain life.
Climate change is natural and natural climate change is occurring constantly. However, natural climate change has been overtaken by human induced climate change which is causing the majority of climate change we are seeing today.
Everyone needs to respire in order to live, which includes plants and animals. Trees and plants help to regulate the carbon cycle. When the trees take in the carbon dioxide from the environment, they give back to oxygen. When trees are cut down, there is a break in the carbon cycle, and there is no exchange in both oxygen and carbon dioxide which causes a spike in carbon dioxide levels. When these occur carbon dioxide moves in the atmosphere and stores there as a greenhouse gas. “However, deforestation still remains the second leading cause of greenhouse gas emissions, just behind industrial emissions” (Culas). Greenhouse gases disturb the normal regulation of the weather. When greenhouse captures and stores heat problems occur. When the carbon dioxide levels in the greenhouse gases are increased, then the atmospheric conditions becomes unstable, which causes global warming. Global warming is the increase in the temperature of the earth, which is mostly caused by the greenhouse effects. Global warming present itself by affecting the environment by causing drought, floods, change in ecosystem, less fresh water available and other environmental issues. Trees play a big role not only in keeping the soil rich, regulating the water table, providing a stable anchor for soil to lessen soil erosion and providing nutrient rich soil for agriculture but it also helps in the absorption of carbon emission in the atmosphere.
Humans have caused global warming by doing many things but the main three are burning of fossil fuels and green house gas emission, deforestation, and excessive use of chemical fertilizers. Global warming is like a bad dream going worse.
Human beings have increased the Human beings have increased the CO2 concentration in the atmosphere by about thirty percent, concentration in the atmosphere by about thirty percent, CO2 spread in atmosphere from human breath, industries , smoke of automobiles and fossil fuel etc… when we burn fossil fuel the co2 gases escaped in to air and outer layer of earth. Outer layer of is the layer that reflect the ultraviolet rays of sun. So the co2 and burning gases causes the increase of global warming
As we approach the future we are faced with many global problems. Most of these problems arise because we have caused them ourselves. We need to face these problems and find a solution. Global warming, although most often overlooked in importance, is a crucial problem of the future directly related to human activities. Global warming is caused by gases humans release into the atmosphere called anthropogenic gases and by deforestation. Anthropogenic gases include carbon dioxide, methane, chlorofluorocarbons (CFCs), hydrofl...
The worldwide increase in temperature and the resulting climate change, known as Global Warming, could be a threat to the environment and have serious negative effects on all living things, including humans. Scientists agree that the temperatures on Earth are rising, but an agreement on what is causing it has not been reached yet, and how the government should address the problem is still being discussed. The debate is between who consider the climate change in the last century a completely natural event, something that already happened through history, with the Earth having periods of increasing and decreasing of temperatures, and think that can’t be stopped or changed by people, and who consider humans and industries the reason why Earth
These changes are becoming more prevalent in our world today, in the past 150 years. Scientists have been analyzing the causes and effects of the greenhouse effect and many other issues that global warming has presented. As John Houghton states in his book, Global Warming the Complete Briefing, on page 2, “The 1980s and 1990s were unusually warm. Globally speaking, the decades have been the warmest since accurate records began somewhat over a hundred years ago and these unusually warm years are continuing into the twenty-first century.” There are countless records that show that our world as a whole is getting warmer, and the facts cannot be disputed.
One of the most substantial problems in the world today is global warming. This gradual warming of the earth is in occurrence at an extremely slow rate but it is happening. Many scientists believe that as human’s work and release greenhouse gases into the earth’s atmosphere, it can become dangerous for the long lasting life of humans and our environment. “Unless we take immediate action, the impacts of global warming will continue to intensify, grow ever more costly and damaging, and increasingly affect the entire planet - including you, your community, and your family” (“Global Warming Impacts”). Everyone should be knowledgeable about global warming and the dangers that it brings to our planet. This essay will examine
Although some believe that Global Warming has been created due to manmade pollutants, I believe that Global Warming is a natural process that has been accelerated due to the excess emissions of pollutants from nature and manmade devices into the atmosphere. The world has been said to be on a cycle of global warming and cooling, this process can neither be stopped nor prevented, but it can be accelerated with the addition of non-natural emissions from automobiles and factories; because this is a natural process, even if constraints were to be put on the amount of pollutants released into the air global warming could not be prevented—it could only be slowed. When the inevitable happens and global warming occurs, there are many effects that our environment, and world, will receive—these effects can cause many different natural disasters that will affect the lives of humans, animals, and plants.
