Environmental Factors : The Causes And Effects Of Global Warming

Most climate scientists agree with the idea that the main cause of the current global warming trend is human expansion of the "greenhouse effect", warming that results when the atmosphere traps heat radiating from Earth toward space. Over the last century, the burning of fossil fuels like coal and oil has increased the concentration of atmospheric carbon dioxide (CO2). This happens because the coal or oil burning process combines carbon with oxygen in the air to make CO2. To a lesser extent, the clearing of land for agriculture, industry, and other human activities has increased concentrations of greenhouse

Humans are pouring carbon dioxide into the atmosphere at a much faster rate than the rate at which plants and oceans can absorb it. Global warming is the increase in the overall temperature of the Earth 's atmosphere; global warming is a delicate topic because it is happening right now no one can stop it from happening. It is already transforming life on Earth, shifting the seasons, raising the temperature and rising the sea level. Other effects of global warming include stronger storms, extinction of species, rapid disappearance of Artic ice, and the increase of the ozone hole. It became an issue in 1988 when a scientist from NASA found that "Global warming has reached a level such that we can ascribe with a high degree of confidence a cause and effect relationship between the greenhouse effect and observed warming" (Hansen). James E. Hansen testimony was a big thing that everyone start to worry about it and everyone was talking about global warming because the media contribute to it. Global warming is a big thing happening right now but we don’t listen to others and we continue with our life’s without looking around us and without helping to stop the cause of it because as a humans we make errors during life but we learn from the errors and the bad choices. Although some people believe mankind is not responsible for global warming, it is a serious problem worldwide and measures are need to help slow the problem.

Researches reveal that natural events as well as human related activities contribute to changes in average global temperatures. AtKisson affirms that global warming is basically a result of increased emission of greenhouse gases into the atmosphere. This atmospheric carbon dioxide (co2) comes from anthropogenic (caused by humans) sources. The concentration of greenhouse gas carbon dioxide, nitrous gases, and methane in the atmosphere has increased evidently due to human activities since 1800. NASA’s article adds:

Have you ever asked yourself what does the global warming mean? What is it caused by? According to Dictionary.com global warming means, “An increase in the earth's average atmospheric temperature that causes corresponding changes in climate and that may result from the greenhouse effect.” Svante Arrhenius, the Swedish chemist who coined the term of global warming in 1896 and launched the theory, says that the burning of fossil fuels will increase the amount of carbon dioxide in the atmosphere and that will lead to increase global temperatures. Also, he concluded that in the case of doubled carbon dioxide concentrations in the atmosphere, we would see a higher rate of 4 to 5 degrees Celsius in the glob’s temperature. That what we could see today because of the atmosphere currently contains 380 ppm of carbon dioxide gas, which is the primary cause of global warming, compared with the 275 ppm that existed in the atmosphere before the Industrial Revolution. The most important gas that plays role in the temperature rising is methane; it consists of the interactions of microbial in rice paddies and ruminant livestock and burning of biomass, which are trees, plants, and animal waste, also as the result of water from the swamp muddy. In addition to methane gas, there is the nitrous oxide which consists of microbial interactions occur in water and soil. Moreover, there is a group of CFC gases which cause erosion of the ozone layer, and finally ozone gas which is

The earth’s climate is predicted to change because human activities are altering the chemical composition of the atmosphere through the buildup of greenhouse gases –– primarily carbon dioxide, methane, and nitrous oxide. The heat-trapping property of these gases is undisputed. Although uncertainty exists about exactly how earth’’s climate responds to these gases, global temperatures are rising. Go to the Emissions section for much more on greenhouse gases.

Over the last 650,000 years the Earth’s climate has been through about seven ice ages(“Climate change: How do we know”). The

During the past century, human activities have released large amounts of carbon dioxide and other greenhouse gases into the atmosphere. Most of the gases come from burning fossil fuels to produce energy. Greenhouse gases, such as carbon dioxide, is absorb and emits heat into the earth’s atmosphere, keeping the Earth warm enough to support life. However, human activities, such as burning fossil fuels, are adding large amounts of greenhouse gases to the atmosphere. Greenhouse gases are like a blanket around the Earth, trapping energy in the atmosphere and causing it to warm. This is called the greenhouse effect and it is natural and necessary to support life on earth. However, while greenhouse gases buildup, the climate changes and result in dangerous effects to human health and ecosystems. People have adapted to the stable climate we have enjoyed since the last ice age which ended several thousand years ago. A warmer climate can bring changes that can affect our water supplies, agriculture, power and transportation systems, the natural environment, and even our own health and safety. There are some climate changes that are unavoidable and nothing can be done about it. For example, carbon

Global warming is defined as a gradual increase in the overall temperature of the earth 's atmosphere generally attributed to the greenhouse effect caused by increased levels of carbon dioxide, chlorofluorocarbons, and other pollutants. These pollutants first made their debut during the industrial revolution and have been polluting the Earth ever since. In other words, we have been sending pollutants into the air for just about 250 years. The reason that these pollutants make the Earth hotter is because of something called the greenhouse effect. Normally the radiation from the Sun would bounce off the Earth and head back into space, however, CO2 pollutants and other greenhouse gasses trap this heat and make the Earth hotter. These gasses can last in the air from decades to centuries, trapping heat in the Earth’s atmosphere over the years. According to climatologists the temperature of the Earth has risen between .4 and .8 degrees Celsius. Scientists from the Intergovernmental Panel on Climate say that by 2100 global temperatures could rise by as much as 5.8

Global warming refers to the rise in the average temperature of the Earth’s surface, oceans and atmosphere due to the increasing concentrations of greenhouse gases. These gases exist naturally, trapping heat and keeping the Earth warm enough for survival, but it’s the larger quantities of these same gases, produced by humans, trapping more heat in the atmosphere, having a negative impact on the planet. Many greenhouse-gas-emitting activities are a fundamental part of modern life, for example, Carbon dioxide, by far the largest

Man-made climate change, or global warming, is caused by the release of certain types of gas into the atmosphere. The dominant man-made greenhouse gas is carbon dioxide (CO2), which is emitted whenever we burn fossil fuels in homes, factories or power stations. But other greenhouse gases are also important. Methane (CH4), for example, which is emitted mainly by agriculture and landfill sites, is 25 times more potent per kilogram than CO2. Even more potent but

Climate change is an issue that affects all, from the smallest bacteria to the largest mammal. Climate change is causing glaciers to melt, move, and in some cases kill people, animals to go extinct or be labeled as endangered because they can not adapt to their changing environment, and numerous other horrendous examples. Climate change can even cause more intense tropical storms, more recent and intense droughts and/or heat waves, and it can also cause sea levels to rise. These are just a few examples of the effects of climate change, but there are even more devastating effects such as polar bears having to search for new food sources, and new land, because the antarctic sea ice they rely on for hunting and living is melting at a more rapid pace. The polar bear is just one of many species affected by climate change, other species include the golden toad, coral, and the green sea turtle. However, since climate change is such a complex issue, only a few solutions have been presented that fix every issue climate change is causing. Former President Barack Obama even stated that “There’s one issue that will define the contours of this century more dramatically than any other, and that is the urgent threat of a changing climate” (15 Quotes on climate change by world leaders, 2017). A primary contributor to these worsening effects are humans extracting and burning fossil fuels, such as coal or petroleum, causing the release of carbon dioxide, a “greenhouse gas,” and many other gases into Earth’s atmosphere. Unfortunately, most people do not know the true magnitude of the issues that climate change creates on a global scale.

Greenhouse Gases (GHGS) absorb part of the infrared solar radiation reflected by the Earth and as a result, it remains hot enough to make life on earth possible. However, the human being has altered the natural greenhouse effect, making it one of the most serious threats to sustainable development. In recent years, several human activities have caused the excessive emission of greenhouse gas, mainly carbon dioxide (CO2), which is responsible for nearly 50-60% of the global warming scheduled for the next few years (Maslin). In this way, we have exceeded the capacity of absorption of the Earth, which raises the heat retained in the Earth 's surface and gradually increases the global temperature of the planet (Maslin).

Global warming refers to the rise in global average temperature caused by greenhouse gases such as carbon dioxide, methane, nitrous oxide, ozone, hydrochlorofluocarbons, hydrofluocarbons, chlofluocarbons and sulphurhexafluoride. Much like covering oneself with a blanket and feeling warm, greenhouse gases absorb infrared radiation from the sun which ensure favorable temperatures for living organisms and life processes. However, when such gases exceed acceptable concentrations in the atmosphere they absorb more heat and thus cause a rise in atmospheric temperature. In recent past, there has been growing criticism of whether global warming is real and more so that it has been caused by human activities.

Global warming is the trend of continuing increases in the average temperature of the earth’s atmosphere. It has a parallel effect of climate change in our planet earth which will be disastrous to the health of the people and ecosystem if not reduced to a minimum level. One of the primary causes of global warming is the burning of coal which is the most carbon rich of all fossil fuels used to produce energy. As we burn fossil fuels like coal, oil, and natural gas for energy, carbon dioxide sips through the air and is lodged into the atmosphere thus creating a “greenhouse effect”. A “greenhouse effect” is created when more emissions of carbon dioxide cause the mass of greenhouse gases protecting the earth from the scorching heat of the sun to become thicker and as they envelop the earth, result in a warmer temperature. Even when the heat effects of volcanoes and other misleading weather phenomena that would make the temperature of the earth seem higher than it actually is are taken out of consideration, studies show that the surface temperature of the earth has been increasing at a rate of 0.17 degrees Celsius per decade [Haines et al., 1998]. These figures are not consistent with a natural trend, and, when one considers the tens of thousands of years in which humans have populated the earth, and that humans have really only started burning fossil fuels heavily since the

Greenhouse gases are compounds in the atmosphere that can trap and hold extra heat, which increases the temperature in the atmosphere. Greenhouse gases is the cause of the greenhouse effect that leads up to global warming. The greenhouse effect is the trapping of the sun’s warmth in the lower atmosphere that is due to the visible radiation from the sun. The solar radiation reaches the Earth’s atmosphere, then the rest of the sun's energy is absorbed by the oceans and lands which result in the heating of the Earth. After that the heat from the Earth goes towards space, some of the heat is trapped in the atmosphere by greenhouses gases which make the Earth warm enough to tolerate living life. The burning of fossil fuels and land clearing start to increase the number of greenhouse gases which travels into the atmosphere. The result of trapping extra heat cause the Earth’s temperature to rise. Scientist's has proven that the constant increase of heat in the atmosphere is caused by humans. The reason humans are proven guilty for the increase of global warming is because of the amount of carbon that is put into the atmosphere. Carbon is released from burning coal, oil, and gas or cutting down and burning forests. Carbon (CO2) is known as the main source of heat-trapping gas which is mainly responsible for the increase of warming over the years. The removal of trees is another cause of global
