Global Warming.
Introduction
Global warming is observed as a steady upsurge in the general temperature of the earth 's atmospheric setting, which is mainly attributed to the greenhouse consequences due to amplified intensities of various air contaminants such as the carbon dioxide and chlorofluorocarbons. Being one of the deadliest menace, currently confronting the word, experts have resolved that massive and uncontrolled production of these greenhouse gasses has contributed greatly to the heating effect on the atmosphere, which has shown to be unsafe and hazardous, not only to the human beings but also to all other living creatures. This paper seeks to explore research on what role does human

The most anticipated effects of a hotter climate are perceived to be the alteration of the local weather configurations and patterns. Additionally, this would have reflective consequences on the agricultural production in the current universe that is certainly unable to sufficiently provide for its dwellers. Social conflict as a result of irregular redistribution of resources would be inevitable. The constant and uncontrolled generation of greenhouse gasses will have bitter consequences far worse than producing a marginally milder climate (Spencer, Roy, 2012).
What role does human activity play in the current global warming trend?
Human beings, generally have a massive bearing on the environmental platform in several ways. The main effects include the diminishing of the water quality, amplification of the greenhouse gas emissions, exhaustion of natural resources and also influence to the general global climatic variations. Reflecting on the water and aquatic systems, humans have exhausted the nutrients such as the nitrogen and phosphorous which are very much critical to the vigor and existence of the aquatic living creature (Smith, Philip and Nicolas Howe). Consequently, human beings contribute in the introduction of large quantities of these constituents, mainly through fertilizers. Too much of anything is poisonous, and for this very factor, water quality is eventually depleted leading to overgrowth of particular microorganisms that exhaustion of oxygen
In the last 100 years, the amount of greenhouse gases in the atmosphere has increased, causing the Earth to warm by an average of 0.6 degrees celsius, largely a result of burning fossil fuels for energy, transportation, and land use changes increased for food production. The basic science is straightforward and climate researchers have shown that gases such as carbon dioxide, methane and others can trap heat in the Earth’s atmosphere, causing a phenomenon known as the greenhouse effect. Human activities such as industry, transport, energy generation and deforestation all produce these greenhouse gases. In the last 20 years, concern has grown that global warming is inevitable and now considered most probably caused by man-made increases in
There are always two sides to every story and every different point of view has a right to be heard. When it comes to the discussion of global warming—a gradual increase in the earth’s surface temperature—there are two very distinct and opposing points of view. The world seems to be split between global warming being caused by humans and it being a natural occurrence; the latter being the viewpoint that I strongly support due to the evidence I will present in detailin this paper. In contrast, I will also discuss, in Part II, the “anti-thesis” or the opposing viewpoint that humans are actually the
We ask ourselves how might human activities have affected global climate change? Well human activities contribute to climate by causing changes in earth's atmosphere in the amounts of greenhouse gases and cloudiness. Mostly it is burning fossil fuels. This releases carbon dioxide gas to the atmosphere. There are many ways that the humans can affect our environment. Deforestation, burning fossil fuels, and hydrocarbons are ways this can affect. In this paper i will explain how each one contributes to global warming. I will support my discussion with evidence and consequences of the effects of each activity. It will also have alternate energy and solutions included that are most sustainable in our area.
Global Warming has silently crept into our society today because of big business, lack of technology, and greed. And now with a new generation of citizens who understand what we have been doing to our earth have to stand up and do what is right. Global Warming refers to the increase in the earth’s average temperature induced by human activity. Most discussions on Global Warming today show similarities between an increase in global temperature and the increase in carbon dioxide, nitrous oxide, methane, and chlorofluorocarbons in the atmosphere. Human activity increases the amount of these gases in the atmosphere and, as a result of the greenhouse effect, increases
Global warming is one of the most controversial topics in the world today. Global warming describes a condition where the average temperature of the earth’s atmosphere and oceans increase. Global warming is predicted to have significant harmful effects on life on earth. The controversy arises from conflicting evidence in the scientific community as to whether humans are contributing to global warming, whether it is a result of natural forces that are beyond the control of humans, or in some cases, whether it is even occurring at all. This research will examine credible evidence of global warming and will explore its causes and
Climate change is a threat that has been in existences for years, but appears to be a greater threat to the world currently. According to the Fourth Assessment Report of the Intergovernmental Panel on Climate Change, there is more than 90 percent certainty that emissions of heat-trapping gases from human activities have caused “most of the observed increase in globally averaged temperatures since the mid-20th century” (IPCC, 2007).
Human activity has poured their gases into the atmosphere. The temperature of the earth’s atmosphere has been rising, and it continues to rise” (Cunningham 138). Since the creation of the gas engine and the use of nuclear energy to power the world's population, the climate has been taking a turn for the worse. But if the world’s population
Exploitive human actions damage the earth. Human’s daily habits cause rising temperatures from carbon dioxide emissions. The excessive use of coal, oil, and natural gas leads to more carbon dioxide emissions, which traps more heat causing the temperature to rise (Friedman 32). For example, in the last 100 years, scientists measured an increase in atmospheric carbon dioxide from 280ppm to 400ppm (124). Based on research conducted by NOAA, temperature and the concentration of atmospheric carbon dioxide have a strong correlation. Temperature rises as carbon dioxide rises. The growing population of the world leads to increased exponential resource consumption and growing levels of carbon
For a considerable length of time and decades, human processing plants and autos have released billions of huge amounts of fake nursery gasses into the air, and the atmosphere has started to hint at numerous an unnatural weather change. Then again, some individuals need you to trust that an Earth-wide temperature boost does not exist. There are numerous individuals who are out for individual pick up and are through and through liars. As indicated by a researcher at NASA "An unnatural weather change is the single biggest danger to our planet”. In the course of the last two hundred years we have seen noteworthy changes in the consequences for our surroundings, basically because of people
Global warming has been a controversial topic for years and some have even denied its existence; however, as more studies are being published every day in regards to our changing climate, it is hard to ignore this growing issue and how humans contribute to it. The term greenhouse gases refers to the group of gases that are primarily responsible for global warming and chief among these gases is carbon dioxide. Rising carbon dioxide levels can be attributed to a combination of burning fossil fuels such as coal, natural gas, and petroleum as well as deforestation in general ( Source A). To slow the effects of global warming, it is important for leaders in our society to consider their greenhouse gas emissions, especially carbon dioxide, and make
The earth is a beautiful and extraordinary planet, but are we treating it right? For the past 20 decades, temperatures have been rising along with hundreds of factors contributing to it. Climate change concerns the public as they wonder if its occurring, how much has occurred in the modern era, what has caused it, what the effects will be if we don’t do anything about it and much more. Many people and scientist agree that mankind is the number one cause of climate change. Humans have influenced this by greenhouse gases, methane nitrous oxide.
In recent years, the controversial subject of global warming has been more predominantly brought to our attention. Is the threat of global warming real? Is it man-made or is this just a natural cycle of earth? Does it really affect earth’s inhabitants? Should action be taken against it? If so, what kind and to what extent? It cannot be only a coincidence that the alarmingly rapid climate change coincides perfectly with the increased amount of pollutants that humans release into the environment. The once stable climate has in recent years begun to skyrocket, thus altering the delicate structure of earthly life. This proves to be hazardous to the future of the planet; some people worry that many of the resources the environment provides that
The concept of global warming has become one of the most widely debated and controversial topics of our time. Scientists learned long ago that the earth’s climate has powerfully shaped the history of humanity. However, it is only in the past few decades that research has revealed that humans have a significant influence on the climate as well. A growing body of scientific evidence indicates that since 1950, the world’s climate has been warming, primarily as a result of emissions from the burning of fossil fuels and the destruction of tropical forests. More importantly, an article titled "Global Warming" published in the New York Times shows that methane, a gas that is emitted from landfills, livestock and oil gas facilities,
The issue of global warming should be on the list of our top priorities. Studies show that the average of global temperatures have risen since the Industrial Revolution began. Since the Industrial Revolution, human emissions has quadrupled the frequency of certain heat extremes and many scientists have warned that a failure to bring greenhouse gases under control could eventually lead to a 62-fold increase in extreme heat blasts (Gillis Justin A17). Most of the increase is due to human activities, especially the burning of fossil fuels and deforestation. These activities contribute to a build-up in carbon dioxide and other gases in Earth’s atmosphere. The Earth’s atmosphere is made of gases like nitrogen, carbon dioxide and oxygen. These gases act as a blanket that covers and gives us warmth, but once these gases such as carbon dioxide absorbs heat, but does not release it back into space in which causes the increase in global temperature. This is called the greenhouse effect because it only traps heat but does not release it.
Global warming is the constant increase of temperature in the earth’s atmosphere that is caused by the increase of carbon dioxide, chlorofluorocarbons, greenhouse gases and many other pollutants. Chlorofluorocarbons are any type of compounds of carbon, hydrogen, chlorine, and fluorine which are harmful to the ozone layer. Global warming can affect many things, one example is the rising of temperature which can result in different types of disasters like storms, heat waves, floods, and droughts. Global warming also causes Higher death rates, Dirtier air, Higher wildlife extinction rates, the increase of Acidic Oceans, and Higher seas levels. In this essay, I will provide information that will show how harmful global warming can be to not only the earth but to humans and animals, and what we can do to prevent it from increasing.
