Recommended: Causes of global warming

At first thought the essay topic global warming, seemed simple. After researching many sites, such as National Aeronautics and Space Administration (NASA), University studies, Intergovernmental Panel on Climate Change (IPCC) studies, Nongovernmental International Panel on Climate Change (NIPCC), and more, global warming is very complicated. It hinges on many factors, solar activity, deforestation, increase in carbon dioxide from forest floors, obliquity (change in axil tilt of Earth), volcano eruptions, water vapor, fossil fuel use, methane gases, cloud cover and other factors. There are many effects on the global temperature, two of the major ways used to study this topic are Global Climate Models (GCM) and observational studies conducted all over the world. The majority of scientific studies indicate that the main cause of global warming is, increased levels of carbon dioxide into the atmosphere. Some research shows that natural occurrences are the main source of global warming. This essay will argue that carbon dioxide released into the atmosphere, by man-made actions is the main reason for the global temperature changes, secondary, are natural occurrences.

Some believe that, carbon dioxide in the atmosphere causes a warming effect on the atmosphere. This carbon dioxide, as the majority of studies have shown, has contributed to the rise in global temperature. There has been a lot of research to explain this. One of the best ways to study global warming are computer models. Computer models use mathematical equations in

  • Global Warming Is Eroding Glacial Ice

    846 Words  | 2 Pages

    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.

    Firstly, global warming is said to be caused by the high levels of carbon dioxide released into the atmosphere by humans. Smoke produced by factories, vehicular exhaust, and the burning of fossil fuels such as coal in power plants are the primary sources of carbon dioxide. The theory is that carbon dioxide being released into the Earth's atmosphere is steadily building up because it cannot escape into space. The theory as to why the carbon dioxide in the atmosphere actually causes the Earth's average temperature to rise is outlined as follows:

    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 Pros and Cons of Global Warming

    1474 Words  | 3 Pages

    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.

    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.

  • Carbon Dioxide

    647 Words  | 2 Pages

    The amount of CO2 in a planet's atmosphere affects the temperature of the planet. As more and more CO2 builds up in the atmosphere, less heat can escape and the planet gets hotter. The CO2 traps radiation from the sun like a greenhouse. This is called global warming or the greenhouse effect. Global warming is becoming a serious problem and CO2 is the major cause. The earth is now warmer than it has been in 1000's of years. The amount of CO2 deposited in the earth's atmosphere from human activities is expected to double by the year 2050. It could possible increase by four in the future with developing countries, such as China, anxious to improve their standard of living.

  • Global Warming Is A Global Issue

    1043 Words  | 3 Pages

    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.
