Recommended: Effects of using fossil fuels on our environment

Global warming means the rise in the mean global temperature to a level which affects the life-forms on the earth surface. The factors responsible for this warming may be both natural and human induced. For the past centuries human reaction with an environment for industrialization was bad for the betterment of their livelihood pollution level increased which is caused largely by human activities. Therefore significant evidences of global warming due to green house gas, increased in global temperature, increase in sea level, and retreat of Himalayan glaciers are based on human induced. Wright and Broose says that enough access to food, water and energy for survival, people are compelled to utilize the resources to fulfill the standard of living, there is disturbance to the natural balance of environment by burning fossil fuels and releasing greater amount of carbon dioxide in to the atmosphere.(Wright&Broose,2011) In this regard deforestation which depletes environment and the efficiency by which carbon dioxide is stored and oxygen released by the green plants are decreased to a huge rate in turn causing increased concentration of carbon dioxide that leads to increased greenhouse effect. According to Miller and Spoolman; Cleaning of toxic carbon monoxide to non toxic carbon dioxide by ecosystem are no more happening because natural ecosystem are depleted and exposure of CO2 in the air will disturbs the balance of green house gas enabling the earth to warm. (Miller & Douglas.2007.). Human contributing in the emission of green house gases which includes carbon dioxide, methane and other toxic gases have been the warming elements as state in the report on IPCC to warm the atmosphere. (IPCC, 2007). Green house that maintains the earth at a comfortable temperature range, basically due to the proper carbon dioxide balance in to the atmosphere is not happening today. Ramanatham and Feng states that manufacturing industries to produce goods needs fossil fuels to run the engine and people using automobiles emits large amount of black carbon in the air, and there is no green ecosystem to absorb the CO2 which was emitted by human activities. This has created greater percentage of energy to warm planet by more than 2% (Ramanathan, & Feng, 2008). The use of natural environment without proper management for the future uses by humans can deplete the balanced ecosystem that will have negative impact on the performance of the system.

  • Global Warming Is Eroding Glacial Ice

    People are responsible for higher carbon dioxide atmosphere emissions, while the Earth is now into the Little Ice Age, or just behind it. These factors together cause many years discussions of the main sources of climate changes and the temperature increasing as a result of human been or natural changes and its consequences; even if its lead to the global warming, or to the Earth’s cooling. In their articles, “Global Warming Is Eroding Glacial Ice” by Andrew C. Revkin and “Global Warming Is Not a Threat to Polar Ice” by Philip Stott, both authors discuss these two theories (Revkin 340; Stott 344). Revkin is right that global warming is taking place. Significant increase of carbon dioxide in the atmosphere is due to human activities combined with natural factors such as volcanic emissions and solar radiation – all together they lead to climate changes and temperatures rising. At the same time, other factors such as deforestation contribute to environmental changes for some glaciers not less than air pollution. However, during global warming not all regions of the planet are affected in the same way, local warming and cooling are both possible during these changes.

    Since the start of the Industrial Revolution, we have been using fossil fuels to power our lives, and factories. Little did we know that our miracle energy producer was destroying our planet. The burning of fossil fuels produces a byproduct called carbon dioxide. This natural occurring gas does not harm the planet in any way when released in small quantities, but at the rate we have released it, there is nowhere for it to go so it becomes trapped in the atmosphere. When the gas becomes trapped in the atmosphere, it creates a “Green House” effect. This effect causes the surface temperature to rise, which has adverse effects on the planet. A number of bills to regulate carbon dioxide released into the atmosphere have been proposed and even accepted,

    Global warming and global climate change is the study of future increases of temperature across the globe. Studying climate change refers to how the over- all climate will change such as the dry places getting dryer and the wet places getting wetter. Global climate is dependent on “the greenhouse effect a natural process that helps regulate temperature” (Easterling and Karl). In the past few centuries humans have had a monumental effect on increasing of greenhouse gases in the atmosphere. Climate change is result of the increase amount of the greenhouse gasses in the atmosphere such as methane, carbon dioxide, water vapor, nitrous oxide, and ozone. “Global temperature has rose approximately 1.4 degrees Fahrenheit over

    The climate on the Earth is changing. Ice age is interleaved with the global warming. In the present age, the temperature of the Earth's climate system continue rapidly increase and it leads to global warming. Global warming is the process of gradual growth of average annual temperature of the atmosphere of the Earth and World ocean. The average temperature on the Earth was increased by 0.6C. There are various reasons of global warming, such as human activities, natural events, increasing of gases, such as carbon dioxide in atmosphere and solar activity (Global warming). Nearly 200 countries have signed Kyoto Protocol and they must reduce four greenhouse gases, in order to struggle with global warming. There are several perspectives about effects of global warming on environment. In this essay will be considered the impacts and consequences of global warming . In the process, it will be clarified that there are positive and negative impacts of global warming.

    The commonly debated “greenhouse effect” refers to “the global average temperature increase that has been observed over the last one hundred years or more” (Spencer). President Barack Obama addressed the issue in an effort to highlight its severity, "We have to all shoulder the responsibility for keeping the planet habitable, or we’re going to suffer the consequences – together” (Leader). The earth’s increasing atmospheric and oceanic temperatures result in climate changes due to cumulative amounts of carbon dioxide (CO2) in the atmosphere. As an outcome, researchers around the globe have established that the by-product of burning fossil fuels is the main culprit of the increasing temperatures. Global carbon emissions from fossil fuels have significantly increased since 1900, as shown above from a study carried out by the Carbon Dioxide Information Analysis Center.

    Many climate scientists, researchers, and environmentalists are expressing concerns about shifts in the overall climate of the earth. It is believed that a dramatically dangerous warming is taking place in the overall global climate, a problem that is referred to as "global warming”. Global warming is the observed century-scale rise in the average temperature of Earth’s climate system. This temperature rise is due to the damaging effects of deforestation and the burning of fossil fuels. It is our responsibility to preserve our planet and our way of living but in order to do that we need to act now. If we continue to destroy the planet with no regard as to how serious this matter is there could be several negative effects to us as human being and other living thing on Earth. This is why global warming is truly a global issue and needs to be tackled collectively. We must to act now in order to reduce the dangerous levels of carbon dioxide emissions and we must to work together.

    As Robert Frost once said, “ Some say the world will end in fire, some say in ice. From what I’ve tasted of desire I hold with those who favor fire.” This excerpt can relate to the idea of global warming. Global warming can be defined as an increase in the earth's average atmospheric temperature that causes corresponding changes in climate and that may result from the greenhouse effect. During the past 10,000 years the earth has been in an ever-growing cycle that has significantly changed the climate. These changes are becoming more prevalent in our world today in the past 150 years. Scientists have been analyzing the causes and effects of the greenhouse effect and many other issues that global warming has presented. As John Houghton states in his book, Global Warming the Complete Briefing, on page 2 “ The 1980s and 1990s were unusually warm. Globally speaking, the decades have been the warmest since accurate records began somewhat over a hundred years ago and these unusually warm years are continuing into the twenty-first century.” There are countless records that show that our world as a whole is getting warmer, and the facts cannot be disputed. Everyone in the world today is experiencing the effects of global warming. These effects might be small now, but if we don’t protect our planet now then the consequences will greatly be increased.

    Global Warming is a condition caused by greenhouse gases and human activities. The increased concentration of greenhouse gases due to activities such as deforestation and fossil fuel burning is causing the Earth’s atmosphere and oceans to warm up. As a result of this, global warming has some serious effects in the shape of extreme weather, species extinctions, and rising sea levels. These effects can contribute to the changes that are taking place all over the world, most of which are dangerous enough to pose a threat to the survival of life on Earth in the future.

  • Global Warming Essay

    1320 Words  | 3 Pages

    The common definition of 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 and other pollutants (Global warming, Wikipedia). Moreover, the effects of global warming will bring ecological and social changes. Because there is no exact way to predict the effects of global warming, it is almost impossible to say how strong global warming will affect life in the future. Scientists blame the greenhouse gas effect in combination with societies greenhouse gas emissions for the rising temperature. The greenhouse effect is a process by which thermal radiation from a planetary surface is absorbed by atmospheric greenhouse gases, and is re-radiated in all directions. Since part of this re-radiation is emitted back towards the earth’s surface and the lower atmosphere, it results in an elevation of the average surface temperature above what it would be in the absence of the gases (Intergovernmental Panel on Climate Change). Simply, global...
