Global heating and cooling has occurred on a cycle for millennia, however in the past thirty years the increased use of energy and fuels by humans has drastically changed this natural occurrence (Juerg, 2007). The largest cause of this warming is the release of carbon dioxide from the burning of fossil fuels. Carbon dioxide levels are twenty-five percent higher than they were in 1957 (UCS, 2013). This seemingly insignificant change has caused a myriad of negative effects. The endangerment of species, rising of sea levels, and increased natural disasters are just a few examples of change brought about by global warming (Juerg, 2007). Even though global climate change presents a massive problem there are many proposed solutions to fix or delay it. These theories range from creating a giant sun shield in space to the simple practice of “reduce, reuse, and recycle” (Gray, 2009). However the most effective solution is to find different sources of fuel to power our day to day lives. The earth is in need of renewable, effective, and long lasting fuels. Global warming can be slowed through the use of renewable energy as it is versatile, clean, a good investment, and can easily be put into place in several different climates and environments. One of the most compelling arguments for the use of renewable energy is how many forms exist of it. Nuclear power, solar power, wind power, tidal power, hydroelectric power, pumped storage, wave power, geothermal power, biomass, and biogas are the most widely known renewable energy sources (Darvill, 2013). This large selection of fuels supports the idea of renewable fuels one day powering the entire planet. All the sources of energy have different niches and benefits.

Energy is the basic necessity of daily life. Nowadays, dependence on fossil fuels for energy needs becoming lower in numerous countries due to the potential of renewable energy to supply sustainable energy to the huge populations in many developing countries who are short of clean and continues energy. Generally, renewable energy can be defined as energy that is derived from natural resources which are constantly replenished and theoretically inexhaustible. Fossil fuels on the other hand can be described as energy that cannot be renewed and will eventually diminish. Thus, in many developing countries renewable energy is the alternative energy to replace non-renewable energy or commonly known as fossil fuels. In addition, according to Sorensen (2004), there is a greater demand for renewable energy sources nowadays due to the uncertainty of fuel price rise in living expenses. Commonly, there are many types of renewable energy available in our world such as wind power, biomass energy, solar energy, hydroelectric power and geothermal energy. However, the main three example of renewable energy are hydroelectric power, solar and biomass energy (Refer to Figure 1 in Appendix 1).
Global warming has become a world wide issue and an issue that is causing great controversy. It is an increase in the earth's atmospheric and oceanic temperatures widely predicted to occur due to an increase in the greenhouse effect resulting especially from pollution (Dictionary). Global warming is a natural process, but because of increase in certain activities this process is taking a faster and more dangerous route creating global problems. Global warming was first theorized in 1894 by Jean Baptiste Joseph Fourier a French mathematician, who noticed the earth was gradually increasing in temperature. He came to the conclusion that the earth’s atmosphere was trapping solar radiation caused by the sun and reflecting this radiation back to earth (History of Global Warming). This theory by Fourier became known as the “greenhouse effect”. In simpler terms the greenhouse effect is where the temperature rises because the sun’s heat and light is trapped in the earth’s atmosphere. In the past one hundred fifty years the average global temperatures have taken a sharp turn upward. The 20th century’s ten warmest years all occurred in the last fifteen years. Also the 20th century was the warmest globally in the last 600 years (Global Warming and Carbon Dioxide, 3). Effects of this increase are the melting of glaciers, rising sea levels, more frequent heat waves and droughts, and heavy rainfall. The burning of fossil fuels such as coal and oil are a main source to why the greenhouse effect is being enhanced and likely contributing to global warming (Global Warming and Carbon Dioxide, 4). To hinder this increase in the global warming process we must reduce CO2 emission, we have to use different sources of energy, and we must recycle.
Background and Audience Relevance: There are always conversations about our planet. We see our earths glaciers melting, weather temperature rising, and pollution affecting our resources. But for some reasons we tend to look away. We should be more aware of this potential event and I’m here to inform everyone about what actually is global warming and the effects of it.
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.

In the search for alternatives to fossil fuels, scientists and policy makers have focused on three options: nuclear power, energy from biomass; and a combination of wind, water, and solar power. Nuclear power, however, is much more costly and runs the risk of having it fall into the wrong hands where it could be turned into a weapon of mass destruction. The third option entails wind turbines, photovoltaic power plants and rooftop systems, concentrated solar thermal power plants,...
As we approach the future we are faced with many global problems. Most of these problems arise because we have caused them ourselves. We need to face these problems and find a solution. Global warming, although most often overlooked in importance, is a crucial problem of the future directly related to human activities. Global warming is caused by gases humans release into the atmosphere called anthropogenic gases and by deforestation. Anthropogenic gases include carbon dioxide, methane, chlorofluorocarbons (CFCs), hydrofl...

Everyone should be knowledgeable about global warming and the dangers that it brings to our planet. This essay will examine Global warming is the gradual rise in temperature and oceans due to recent human activity. This is created by the production of too much carbon dioxide that is released into the earth’s atmosphere.
