Once an uncommon term used only by scientists and climatologists, the notion of Global warming today is commonly heard but very misunderstood. One might ask, what exactly is global warming and should we care? According to "What is Global Warming?" in LiveScience, global warming is a gradual increase in the temperature of Earth's surface and atmosphere, that has become a world-wide environmental issue.1(Lallanilla,2013) Similarly, this topic is one of great controversy because of widely differing opinions on current global warming rates and the impact by humans.This suggested anthropogenic activity creates carbon dioxide, methane, and other gases that are released by the burning of tropical forests and fossil fuels, powering plants, heating homes, and traveling.2(Kessel,2000) On top of rising temperatures, global warming is feared for its effects on climate change, such as rising sea levels and the melting of glaciers, that will ultimately result in a non-sustainable environment and negative health consequences for mankind. Life on earth depends on climate, and changes in it directly effect the health and well-being of the population, biodiversity, and the delivery of services by ecosystems around the world.
Global warming is the increased warming effect of the atmospheric temperature resulting in a change of the Earth’s climate (USGS.gov, 2008). The increase warming of the temperature is the result from two greenhousegases such as carbon dioxide and methane that are being filtered and trapped into the Earth’s atmosphere. The layers of Earth’s atmosphere is to protect life from high-energy radiation and the frigid vacuum of space (nasa.gov, 2010), but if the atmosphere’s layers becomes thinner, its vital role of protection will diminish. Landfill wastes, industries and deforestation are why global warming exists, in turn will affect all life on Earth.

The concept of global warming has become one of the most widely debated and controversial topics of our time. Scientists learned long ago that the earth’s climate has powerfully shaped the history of humanity. However, it is only in the past few decades that research has revealed that humans have a significant influence on the climate as well. A growing body of scientific evidence indicates that since 1950, the world’s climate has been warming, primarily as a result of emissions from the burning of fossil fuels and the destruction of tropical forests. More importantly, an article titled "Global Warming" published in the New York Times shows that methane, a gas that is emitted from landfills, livestock and oil gas facilities, is a close second to the carbon dioxide impact on the atmosphere (“Global Warming”).
The rate at which the earth is warming is what is so alarming, since it can have such a profound negative impact on the ecosystem. Simon et al., (2007) note that prior to the industrial revolution the concentration of CO2 levels in the earth’s atmosphere was roughly 280 parts per million (ppm), however today’s levels are at 385 ppm and still climbing. The earth’s oceans are always in a constant exchange of carbon d... ... middle of paper ... ...ited American Geophysical Union. (2007). AGU Position Statement: Human Impacts on Climate.
We live at a period in time were natural disasters have become a current event in our world. The Earth’s climate is changing, the culprit, global warming. This is what popular media has guided us to believe. What causes global warming, “we do, with the emissions of carbon dioxide we produced”, claimed by the noble prize winning movie, The 11th Hour. Although in reality the Earth’s climate has gone through spikes in climate changes for centuries.

With the population growing everyday it will cause more challenges of climate and energy will only intensify. Global Warming or climate change effects changes in the entire environment. In the last one hundred years the average temperature has gone up by one point eight degrees Fahrenheit. This has caused changes in weather conditions like storm patterns, winds, the growth of plants, and the rise in temperature. It has also caused poles and glaciers to melt having the sea level rise and low-level island to become flooded.
Global warming is a common term used by scientists to describe a consistent rise in the Earth’s average temperature. It is easy to find articles about global warming in environment issue sections. Scientists inform us about the serious state of the Earth warming up, which can be considered one of the greatest nature challenges for the world in 21st century and also a huge threat to humanity. More than ever, this dramatic climate change is receiving special attention from the scientists and environmentalists, who are working out ways of handling the possible consequences. Global warming is a phenomenon when the Earth’s average temperature of the atmosphere and the oceans to rise.
