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”).
Global Warming: “It’s gettin’ hot in here, so take off all your clothes…” The famous words of R&B star, Nelly, are truer than one might think. It really is getting hot in here. The world’s average temperature is rising every year and is expected to be 5 to 10 degrees higher by the end of the century, which is faster than they have increased in the last ten millennia, according to the National Resource Defense Council’s website. But why is this epidemic happening? As the Defense Council states, global warming is caused by carbon dioxide and other types of heat trapping pollution that are collecting like a blanket in the atmosphere, trapping heat from the earth as it tries to radiate back into space.
For decades societies have been concerned about climate change, and in recent years it has sparked a debate as to whether the earth is warming due to causes by humans or through a natural progression. There are scientists on both sides of the debate, but one thing that they can agree on is that the earth is in fact warming. Studies have indicated a rise in the carbon dioxide levels (CO2) in the earth’s atmosphere that can be attributed to the what is known as the greenhouse affect (Simon, Reece, Dickey, 2007). Natural occurring gases such as carbon dioxide, methane, and water vapor act as source for trapping heat into the atmosphere, however CFC’s or chlorofluorocarbons are man made synthetics (Simon et al., 2007). These synthetic gases accumulate to the already natural gases and increase the amount of heat that gets trapped in the atmosphere (Simon et al., 2007).

The melting of the polar icecaps has long been believed to be caused by global warming. Until recently, the cause of global warming itself has largely been up for debate. Now atmospheric scientists attribute global warming to increased greenhouse gases, such as carbon dioxide, in the earth's atmosphere (Greenstone 323). With the knowledge that carbon dioxide causes global warming countries can start taking actions to prevent future global warming.

Global warming extremists want us to believe that as global temperatures rise, so do chances of complete extinction of entire species. Natural disasters will become more common, whole continents could one day be under water, and death rates could be at an all time high. This may seem like a bad science fiction novel, but in some ways they might actually be right. At the very least global warming can and will effect humans living in nearly every region. From those living on the coast, to those living in the Artic plains no area of our planet is safe from global warming.
Global Warming and The Environment Global warming is a term used to describe a gradual increase in the average temperature of the Earth's atmosphere and its oceans (All About Global Warming, 2007, para.1). There is no doubt this is an important matter that will impact planet earth for many years to come. Global warming is a critical issue that impacts the entire world and the potential consequences caused by it will have a negative impact if human contribution is not reduced. Although many people disagree with the causes and outcomes, there is certainly enough information available to support the argument. At this time, global warming is said to be a crisis with carbon and emissions of Co2 being made out to be the culprit (Turpin, 2007, p.30).
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.
The greenhouse effect and humans and their creations and actions are the main reason for global warming causing: melting of ice caps and rise in sea levels, dramatic climate changes, endangerment of animal species, and human health contain and deaths.

Global warming is the increase in the average temperature all over the earth. Global Warming is a major problem in the world today and is argued among all of the world leaders. I am going to talk about how the global warming crisis is being caused. Also, what the people of the world can do to stop the acceleration of the global warming. There are people in the world that believe that there is another reason why this is happening; earth is experiencing a natural cycle of evolution.
