The Cause And Effects Of Global Warming

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

Greenhouse gases and the earth’s temperature have fluctuated at a steady pace throughout scientific history, except in recent decades. Many believe that the advances of the industrial age contributed to the greenhouse effect (national geographic, 2010). This argument is rooted in the belief that global warming is man-made and caused by such things as air pollution and industrial waste (2010).

Climate change is influenced by the greenhouse effect which is the increase of Carbon dioxide, Methane, Ozone and Nitrogen Oxide. On one hand, the presence of these gases in the atmosphere make the earth habitable with respect to regulating the earth’s temperature. However, an increase in the concentration of these gases results in trapping energy in the atmosphere and this in turn increases earth’s temperature. “Global greenhouse gas emissions have grown since pre-industrial times, with an increase of 70% between

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.

Global warming is a broad term that describes the massive global increase in temperature in the last couple hundred years or so. Most scientists agree that there has been a massive spike in the emission of greenhouse gases in those last few hundred years. What they do not agree on is if humans are primarily the cause of the increase in temperature because of our bad habit of dumping greenhouse gases into the atmosphere. Some say that the increase in pollutants is causing the warming, while others say that the amount of gases humans have released into the atmosphere is not enough to affect the world on such a large scale. Unsurprisingly, scientists are deeply divided on one of the biggest problems of the last few decades. Steps have already

The Earth is warming up, so what does this mean for the billions of people that will be affected, if global warming continues? Global warming is the act of Greenhouse Gases; which is Carbon Dioxide, Methane, Nitrous Oxide and Oxygen in the form of water vapor. These greenhouse gases are how the Earth stays warm, heat comes from the sun and with the help of greenhouse gases; the heat from the sun becomes trapped; to keep the Earth warm. Since the industrial revolution, which increased the use of fossil fuel, the Earth’s temperature has been rising at an alarming rate (Gale Video, 2015). Global warming is affecting the lives of billions of people, with extreme weather, effects on food production, and rising health concerns.

Human life have been significantly affected by the industrialization of our planet, consequently resulting in an increased emission of greenhouse gases. These gases have contributed to the increasing temperature of the Earth which is known as Global warming. Of all the greenhouse gases, Carbon dioxide emission have the largest impact that contribute to Global warming. In addition, increasing carbon dioxide emission has become a growing trend in developed countries. The evidence of global warming are glaciers retreating, extreme weather patterns occurings, and animals that depend on cold climates for survival are at risk of being extinct. Even with the evidence of Global Warming, there are some people who does not believe in global warming or see it as an issue that should be addressed. One of the common arguments by non-believers of global warming is that the earth surface temperature was always increasing in the past.

"The amount of heat accumulating on Earth because of human emissions is roughly equivalent the heat released by 400,000 Hiroshima bombs exploding around the world every day," (FactRetriever). The heat is a direct effect from global warming which is becoming more and more relevant in today's societies. There are a number of effects due to the one major cause of global warming, which is greenhouse emission, and those are: increased temperature, melting ice sheets, rising sea levels, increased power of hurricanes due to acidic oceans and surface temperature, and finally, air pollution which increases death rates globally. The quantity of greenhouse emissions in the atmosphere is intensifying due to human activities that burn fossil fuels which in turn is increasing the temperature on earth, causing the oceans to become acidic, and increasing the effects of air pollution.

Have you ever heard about global warming? Global warming is a gradual increase in the temperature of the Earth’s surface both water and land . Years ago, when the Earth experienced an increase in temperature it was a result of natural causes but today it is being caused by the greenhouse gases in the atmosphere produced by human activities. The greenhouse effect occurs because of the presence of specific gases in the atmosphere at a high rate. These gases play a major role in maintaining the earth’s thermal energy. Due to absorbing a portion of the infrared radiation emitted from its surface and retaining it in the atmosphere; Subsequently,  heating the surface of the Earth and maintaining its temperature constant or up to the level that makes life possible. The rise in the greenhouse gases in the atmosphere led to the retention of a larger amount of thermal energy in the Earth, affecting all its operation and system. Global warming affects the planet seriously in several ways including climate change,  melting polar ice caps and widespread extinctions of species.

The world is changing to the point where humans are not able to put things back how they were years ago. Global warming is the concern of many people. Some people show they care by changing their lifestyles and adapting to the world for the temperatures to remain comfortable, and others are continuing to do what they do to make global warming expand. Global warming is “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” (Bradford, 2014). Global warming has caused sea levels to rise, glaciers to melt, and different species to adapt to a new life.

This paper will define global warming and discuss how greenhouse gases affect the Earth. While greenhouse gases are necessary for life to exist on Earth, an overabundance or shortage of greenhouse gases can be detrimental. Human activities have caused an overabundance of these gases, and it is necessary for humans to become aware of how their activities affect the Earth. It is necessary for humans to begin modifying their behaviors that cause global warming and its negative effects, such as severe weather pattern changes, rises in temperatures, effects on agriculture, as well as animal and plant extinctions.

Global warming represents a very large threat to our planet. But first off, what is global warming? It is the significant increase in the Earth’s temperature over a short period time as a result of human activity. A congruous mix of organisms, people, and environments are being harmed. Ocean levels have risen, species are becoming extinct, and the natural world is not what it used to be. Regardless of whether this is a large risk is yet indeterminate, whatever the impacts of global warming may be, it is most likely that the outcomes will be enormous, causing illnesses and financial decay. Because of global warming, many are beginning to invest in energy-efficient supplies and do a variety of other acts. For example, carbon dioxide (C02) is an important factor on earth. It is causing a warming impact on the world's surface range. Since water vapor itself is an ozone depleting substance, this causes significant additional warming. Then, the warming causes more water vapor to be vanished. The C02 level is relied upon to develop in the long haul due to keeping consuming of petroleum derivatives. Different gases, for instance, C02, Sulfur, CFCs, and Methane are additionally in charge of a dangerous atmospheric deviation. Industrialization, urbanization, and deforestation likewise are expanding the generation of these gases.

Global warming over the past 50 years has been experiencing rising global temperatures from the human trend “greenhouse effect”. The role on human activity have produces greenhouse gasses such as carbon dioxide, methane and nitrous oxide causing much of earths temperatures rising over the past 50 years. The impacts of Global warming are fueling frequent droughts, heaver rainfall, hotter heat waves, and powerful hurricanes. Global warming occurs when greenhouse gasses, carbon dioxide, and other hazardous collect in earth’s atmosphere absorbing sunlight and solar radiation trapping heat and causing temperatures to rise. In the United states, the burning of fossil fuels to make electricity is the largest source of pollution, producing carbon dioxide. Fossil fuel burning such as coal and oil power plants are the country’s biggest polluters. The country’s second largest source of carbon pollution is transportation sector. Transportation sectors such as automobiles, planes and trains generates about 1.7 billion tons of carbon dioxide emissions a year. Due to the advancements of scientist, energy efficient technology, modernized power plants now burn less fossil fuels decreasing the emission of carbon dioxide. As a result, the effects of global warming are melting glaciers, effecting agriculture, disruption of habitats, and the spread of conditions favorable to pathogens.

We are facing the consequences of global warming mainly in result of our burning of fossil fuels and releasing heat-trapping gases into our air. Ninety-Seven percent of climate scientists have agreed that the climate trends that have occurred over the past century are likely due to human activities. We have created what is called “the greenhouse effect”; a warming that occurs when the atmosphere traps heat that is radiating from Earth toward space. Sunlight passes through our atmosphere and warms Earth’s surface, this heat is supposed to radiate out into space, but most of the outgoing heat is instead absorbed by certain greenhouse gas molecules that block the heat from escaping, instead emitting into all directions, warming instead the surface of Earth and the lower atmosphere.

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.
