Humans Activity And Climate Change Environmental Sciences Essay

Humans Activity And Climate Change Environmental Sciences Essay Climate change has been occurring on the planet for billions of years since its inception. At different times it has been caused by a catastrophic global event or by the dynamic inner workings of the earth. These climate changes have been proven by science over long periods of time. The big question these days is whether human activity such as the burning of fossil fuels is a major contributor to the climate change of the planet In 2007, the Intergovernmental Panel on Climate Change, stated that human activities contribute to climate change by causing changes in Earths atmosphere in the amounts of greenhouse gases, aerosols (small particles), and cloudiness. The largest known contributing human activity comes from the burning fossil fuels that release carbon dioxide gas to the atmosphere. Greenhouse gases and aerosols affect climate by altering incoming solar radiation and outgoing infrared (thermal) radiation that are part of Earths energy balance. Along with the change in temperatures come heat waves, new wind patterns, worsening drought in some regions, heavier precipitation in others, melting glaciers and Arctic ice and rising global average sea levels. A collaborated effort by hundreds of climate experts and government representatives from 113 countries, believe that climate change is caused by human activities. Most of the observed increase in globally averaged temperature since the mid-twentieth century is very likely due to the observed increase in anthropogenic (human-caused) greenhouse gas concentrations. Climate change is real, rapid and humans are playing a large part in transitioning to a warmer world. Human Activity and Climate Change When I turn the television on, and surf the news channels I get a quick snap shot of the latest events that have unfolded. At any given time Ill be informed of the latest earthquake, tsunami, flood, tornado or drought thats taken place while I was away. I dont remember these uncommon events being in the news as often as they have been. Not only that but they have been more violent as well. The increases in these events are sure indicators that a climate change is occurring on the planet as we speak. Climate change is defined as any long-term significant change in the weather patterns of an area. This has been occurring on the planet for billions of years since its inception. At different times it has been caused by a catastrophic global event or by the dynamic inner workings of the earth. These climate changes have been proven by science over long periods of time. The big question these days is whether human activity such as the burning of fossil fuels is a major contributor to the climate change of the planet. (Desonie, 2012) Humans have reached a level of knowledge and technology that allows us to detect a change in climate, identify the causes and consequences for that change. For example, I live in Twentynine Palms, CA which is located in the Mojave Desert. Climate changes here show a slow warming of the Mojave and Sonoran Desert regions. This warming is altering rainfall and weather patterns, altering plant cover and productivity, plus affecting ecosystem functions and species distribution. Desert ecosystems are predominantly sensitive to changes in atmospheric carbon dioxide. Future rises in atmospheric carbon dioxide will affect rates of plant photosynthesis and water loss, and are predicted to increase efficiency and productivity in certain desert plants. Increased plant productivity, particularly the productivity of invasive grasses, will increase the occurrence of wildfires in the desert. Increased severe and persistent droughts are also predicted for these desert ecosystems. (Webb, 2009) So, sim ply said climate change is already having and will continue to have major implications for plants, wildlife species, and ecosystem processes in this particular region. In 2007, the Intergovernmental Panel on Climate Change, stated that human activities contribute to climate change by causing changes in Earths atmosphere in the amounts of greenhouse gases, aerosols (small particles), and cloudiness. The largest known contributing human activity comes from the burning fossil fuels that release carbon dioxide gas to the atmosphere. Greenhouse gases and aerosols affect climate by altering incoming solar radiation and outgoing infrared (thermal) radiation that are part of Earths energy balance. (Solomon, 2007) Along with the change in temperatures come heat waves, new wind patterns, worsening drought in some regions, heavier precipitation in others, melting glaciers and Arctic ice and rising global average sea levels. (Hogan, 2007) A collaborated effort by hundreds of climate experts and government representatives from 113 countries, believe that climate change is caused by human activities. Most of the observed increase in globally averaged temperature since the mid-twentieth century is very likely due to the observed increase in anthropogenic (human-caused) greenhouse gas concentrations. (Solomon, 2007) Climate change is real, rapid and humans are playing a large part in transitioning to a warmer world. Studies have shown that humans have been burning fossil fuel at an alarming rate. By burning fossil fuels to produce energy to run vehicles or provide electricity, we emit carbon dioxide. Carbon dioxide has been scientifically proven to have harmful effects on the earths atmosphere. (Roach, 2007) The causes and effects of humans burning fossil fuels are easy to understand. By burning fossil fuels we emit carbon dioxide; carbon dioxide in turns depletes our ozone layer. The ozone helps block some of the suns heat and radiation. Without the ozone layer more sunlight, sun heat, and sun radiation reach the surface of the earth. This immediately means warmer temperatures. Warmer temperatures cause climate change. A very simple concept to understand yet the average individual seems to have a nonchalant attitude towards this fact. Granted natural climate change has been occurring for billions of years, but I believe that humans are greatly influencing the current climate change by our own activities. The industrial era for the human race began around 1750 and since this point in time we have been affecting the climate in many ways not known until recently. I also believe that humans are not concerned enough with the consequences that will result from our continued pollution of the earth, I am very surprised with the lack of urgency on our part. (Desonie, 2012) We produce four main greenhouse gases that possibly affect climate change, CO2 (carbon dioxide), CH4 (methane), N2O (nitrous oxide), and halocarbons. All of these types of gases contribute to the depletion of the atmosphere, but CO2, is the one mainly produced from the burning of fossil fuels. Levels of these gases have increased significantly since the industrial era, and are attributed to human activities. Changing the atmospheric abundance or properties of these gases and particles can lead to a warming or cooling of the climate system. (Solomon, 2007) Given the time and resources, there is no limit to what the human mind can do. Unfortunately, much of the knowledge and technology that has been used has had a negative impact on the environment. Yes, climate change is a natural occurring phenomenon as well but we have long been burning fossil fuels use before we understood the consequences. All pollution thats been levied upon the earth was cause by the human animal. So, my answer to the question of whether human activity, especially the burning of fossil fuels, is a major contributor to climate change is, yes, we are.

Environmental Depletion Essay

1. Individuals are affected by the environment in different ways. The environment is an essential element in man’s daily sustenance. The environment is the source of fresh air which humans breath in order to live, the source of fruits and vegetables that are necessary for the better functioning of the body, and the care taker of nature which provides man with a serene view of the world. The environment is also the source of trees and other raw materials that are used in the production of the basic needs of the modern world. The environment aids man in so many ways that living without it is totally indispensable for the survival of man. However, the many blessings and benefits which man derives from the environment have caused greed and abuse. The environment, as many theorize is very sick because of man’s lack of concern for it. Instead of striving to preserve and/ or cultivate all that the environment has to offer, man continues to abuse and show lack of care for the environment. Thus, the world now is experiencing too many nature related tragedies. The tragedies that are happening and the climate changes as well as global warming are all the result of man’s depletion of the earth’s natural resource. Everything which the environment has to offer has been continually abused by man and utilized commercially to satisfy their greed for profit. What man forgets is that whatever he does with the environment will be done to him two fold. Aside from the physical effects, changes in the environment can also have physiologic and psychological effects to man. If the temperature is hot and dry, man tends to be sweaty and thirsty while if the temperature is cold, the body of man tends to cling on to something that will provide him warmth. Psychologically, a hot temperature will most likely cause man to be easily irritated and annoyed. More often than not, the patience is man is shorter when it is hot as compared when the temperature is cold. In addition, if the environment to which man lives in is rowdy or in chaos or there is too much pollution, the tendency of man is also to feel and act in chaos whereas if the environment is serene, man, most often than not, will feel relaxed and relieved. A busy and crowded environment may lead to stress but a lax setting may temper the mind and feelings of man. Individuals, generally, act in accordance with what they see and feel from the environment. There are only a few people who do not feel affected with what is happening in their environment, these are the people who have high tolerance and have a high sense of discipline to detach themselves from the environment where they are. 2. In the past five years, there has been an increased awareness in the environment because man has been feeling the wrath of nature. The effects of the pollution of the water, the seas and rivers, the air and the noise pollution that are felt world wide are starting to cause serious trouble to man’s daily existence. There has been too much pollution around that man can hardly enjoy the benefits which nature used to offer. The climate changes, global warming, extinction of plants, animals and fishes, melting of glaciers and scarcity of natural resources such as water, trees and animals have caused man difficulties. In some parts of the world, such as Africa, water scarcity is very prevalent (Arriens, 2007). The people there hardly have any water to drink, cook and bath. In the years to come, it has been predicted by several scientists and researchers that water scarcity will be felt in a greater degree. If there is water scarcity, almost all resources will be affected. Lack of water will also deprive man to cultivate the soil and plant fruits, vegetables and rich thus there will be food shortage. Cost of products bought in the market will also rise. The lesser products there are available, the higher is the cost. The fear of man to experience all of these adverse effects is the reason why there has been an increased awareness of the environment, which I believe is just right. Man needs to protect and preserve the blessings of nature in order to live longer and enjoy life better.

An after school job can complicate your natural regimen by leaving you with less time to study and complete assignments. As everyone knows, in order to get a decent paying job later in life, finishing high school and some form of college is essential. A report conducted by the Institute of medicine and the National research council found that students who worked as many as fifteen hours per week dropped out of school at higher rates, had lower grades, and were not as likely to attend college. Based on that research, it is exceedingly important to know your limits as a human being, and give yourself the time you need.
