Today, one of the major threats that our planet is facing is the climate change. The temperature of the earth is warming day by day. According to many scientific researches, conducted on climate change have resulted that sudden climatic changes are the cause of global warming in the environment. The term ‘Global Warming’ is defined as the gradual increase in the temperature of the earth’s atmosphere due to the greenhouse effects which results in the corresponding changes in the climate. According to IPCC’s research, Earth’s global temperature is increasing by 1.4 degrees F since 1880. As a result of global warming, there has been occurring imbalance in the environment. Through this research paper, I expect to find out how are the climatic changes due to global warming a threat to our planet? It covers all the effects, present and future consequences of global warming, impact of global warming on the climate, etc. There are various human and natural causes of global warming. All these causes contribute to the amount of greenhouse gases which are the major cause of warming of the earth atmosphere. Human activities like deforestation, burning of fossil fuels, emissions from manufacturing industries, emissions of greenhouse gases like CO2, CFCs, NO2 and halocarbons which is a group of gases containing fluorine, chlorine and bromine. Burning of fossil fuels like petroleum, coal, etc. release carbon which combines with oxygen in the air to form carbon dioxide which is a
The science behind global warming is complex. The major cause of global warming is greenhouse gas pollution the main contributors are tar sand, natural gas, and coal plants. In
Global warming is caused by several things. One of these is the release of carbon dioxide into the greenhouse gases in the atmosphere by using energy generated from burning fossil fuels.
Global-Warming is caused by the planet heating up, due to many greenhouse gases. A greenhouse gas is a type of gas that causes the planet to grow tepid, more than usual and at a quick pace. One specific greenhouse gas is carbon dioxide (CO2). Carbon dioxide is released, and bestowed,
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:
The purpose of this paper is to compare and contrast the arguments made by Berger and Goreham, to determine if an increase in the levels of CO2 in the atmosphere is the primary cause of modern global climate change and if the rise can be attributed to human activities. While in agreement that there is a change in the global climate right now, Berger and Goreham have varying ideas on whether the preponderant cause of this modern climate change is rising carbon dioxide levels, accredited to societies. After further evaluating Berger and Goreham’s arguments, information from scientific journals, will be used in determining which argument holds the most scientific evidence concerning anthropologically created CO2’s influence on global warming.
As decelerating the negative impacts of rising global temperature becomes increasingly important, a myriad of techniques to slow or reverse the effects of global warming are being researched and implemented. Among these are economic incentive programs designed to encourage large corporations to produce fewer green house gases (GHGs), investment in sustainable technology and behavioral education, and so on. Some of the up and coming approaches to achieving more sustainable global temperatures are known as geoengineering, which involves projects that attempt to prevent global temperature increase by "reflecting to space sunlight that would otherwise warm Earth or by removing carbon dioxide from the atmosphere" (Caldeira et al.). Both solar radiation management (SRM) and carbon dioxide removal (CDR) strategies offer attractive options for reducing global temperature rise. CDR proposals include the sequestration of atmospheric CO2 in trees via reforestation, the creation of wetland ecosystems, and modification of ocean upwelling, among others (Caldeira et al.). SRM strategies are a bit more creative, with options like whitening clouds and making plants more reflective to reflect solar radiation off earth 's surface and from the stratosphere. One of the more controversial emerging SRM strategies is the injection of aerosols, namely sulfate, into the stratosphere in order to "scatter the solar radiation back to space" and as a result "reduce global-mean temperatures" (Caldeira et
The main cause for global warming can be accounted to the “human expansion of the greenhouse effect” (“A Blanket around the Earth” par. 1). Humans expand the greenhouse effect through many activities and processes: using landfills, burning fossil fuels, industrialization, deforestation, agriculture, and even the use of livestock. While it seems like these activities would not have much to do with the expansion of the greenhouse effect, they emit gases that can stay in the atmosphere for an extended period. There are gases in the atmosphere that prohibit heat from escaping; the ones that do not react to alterations in temperature “are described as ‘forcing’ climate change” (par. 2). Carbon dioxide, methane, and chlorofluorocarbons are gases whose emissions have increased due to human activities.
One main cause of global warming is the “greenhouse effect”. According to NASA, this can be described as warming that results when the atmosphere traps heat radiating from Earth toward space. Certain gases in the atmosphere, such as nitrous oxide and carbon dioxide, sit in the atmosphere, helping block heat from escaping. Human activities such as biomass burning and the use of commercial and organic fertilizers increase nitrous oxide in the atmosphere. Human activity such as deforestation and burning fossil fuels contribute to adding carbon dioxide into the atmosphere. This directly ties in to the next cause of climate change, rising carbon dioxide levels.
Global warming has many causes contributing to its rapid growth in the last few decades. “A NASA satellite has been mapping the changing amounts of carbon dioxide in Earth's atmosphere. In an image derived from data collected in October 2014, swirls of CO2 emitted by burning fossil fuels in the Northern Hemisphere are clearly visible” (National Geographic). This quote shows that the Northern Hemisphere is more polluted than the Southern Hemisphere, which shows a direct correlation of carbon emissions and other greenhouse gases in highly populated areas with many factories. Also, the other greenhouse gases such as water vapor, methane, and nitrous oxide are becoming more and more common in the atmosphere. Many greenhouse gases are overlooked and people usually just classify it as Carbon Dioxide, but really there are other gases such as methane which is 84 times more potent than Carbon Dioxide. It is just less common. With all these gases in the atmosphere, they start to heat up the Earth. “Global warming occurs when carbon dioxide and other greenhouse gases collect in the atmosphere and absorb sunlight and solar radiation
Climate change is one of the most important issues on the global political agenda. This is a priority topic not only for the United Nations and its Secretary-General Ban Ki-moon, but also for political, economic and religious leaders, including Pope Francis that also urges to take measures to curb global warming.
The greenhouse effect is the result of the interaction of the atmosphere of a world and the radiation emitted from the Sun and planet. This process essentially makes a world warmer that it would be. As we will learn in this chapter there are many factors that determine the strength of a world’s greenhouse effect including a world’s size, the world’s distance from the Sun and the strength of a world’s magnetic field. Before you can learn about the factors that influence the greenhouse effect first you must understand how the greenhouse effect works.
I watched in the TV in last years about a lot of phenomena happened by global warming like, increasing the temperature degrees, and melting the snow mountains around the word. However, global warming has played a major role in changing the weather all over the world. The climate change all over the world is a proof that the weather conditions are changing. Global warming has made some of the hottest land cold now and the countries that never had a summer in millenniums are now having sunlight regularly. These are the basic changes that signify that global warming is affecting the whole world. Global climate change is a procedure which is - according to the climate studies - a rapid change in the climate of some countries. The weather of some countries is changing and the climate has changed the pattern which is known as a global climate change. The issue of global warming is very complicated and exceptionally serious, having affected the whole planet over the last decades, it cannot be improved by one effective solution; however, the situation can still be ameliorated through different approaches combined together, such as green transportation, exploring nuclear power, managing forests and agriculture, and phasing out fossil fuel electricity. In this research paper, I will talk about the causes and effects of global warning, the risk of global warming, and finally a few solutions for this epidemic.
A predominant factor as to why global warming happens is more gas particles exposed in the air because of an increase in gases produced by industries. Gases such as CO2 and SO2 are constantly harming our environment by regularly adding more harmful gasses into our atmosphere. Due to forest fires, industries, factories, and new found technology such as the car, many harmful gas molecules are surrounding us. These harmful gas molecules collide with our healthy atmospheric particles which make the amount of gas particles increase dreadfully. Since more collisions between these different particles are occurring, the average kinetic energy is raised therefore the temperature increases as well. As more particles are added into the atmosphere, it becomes denser and gasses are getting trapped into our
Many climate scientists agree that the main cause of global warming today is too much carbon dioxide in our atmosphere, acting as a blanket and trapping heat in, warming the planet. We create global warming by burning fossil fuels (coal, oil, gas etc) and burning down our forests to make plantations. When carbon dioxide is released into our atmosphere, it hangs around for many centuries. The more carbon dioxide released into the air, the more the suns energy gets trapped in our atmosphere as heat and at this rate, by the end of the century, will have risen by six degrees.
The main cause of global warming is due to greenhouse gases as well as other air pollutants that collect in the atmosphere. Sunlight and solar radiation that should have bounced off the earth’s surface is absorbed by these pollutants. If the pollutants weren’t in the atmosphere, radiation would escape into space. Pollutants are known to last as long as centuries within the atmosphere, they trap heat and in turn cause the planet to overheat. This is the greenhouse effect; the greenhouse effect is the cause of global warming.
