Global warming is part of a natural cycle of climate change. The Pleistocene describes the time period that spanned from 1.8 million to approximately 10 000 years ago. During the Pleistocene, significant advances of continental ice sheets in North America and Europe occurred. The Holocene Maximum was a time period that occurred approximately 11 000 years ago and it marked the end of the Ice-age. The temperatures then, were much higher than they are today. The time period between 900 and 1300 AD is known as the Medieval Warm Period ' where higher temperatures were documented in historical accounts. The Little Ice Age took place between the 16th to the mid 19th century. During this period the polar ice caps extended considerably further from the poles than they do currently. Accordingly it is acceptable to state that climate change and hence global warming is part of the Earth’s natural cycle.
It is alleged that global warming is ‘man-made’ due to it being caused by greenhouse gases (most notably Carbon Dioxide) that contribute to the ‘greenhouse effect’. The sun radiates shortwave radiation through the upper part of the atmosphere to the Earth. The Earth’s surface is warmed and the Earth radiates longwave infrared rays to space. Greenhouse gases absorb infrared radiation from the sun and radiate it back to Earth. The Earth’s surface is warmed by the reflected heat which consequently leads to global warming.
Man-made Carbon Dioxide emissions alone cannot be...

- In recent years, the controversial subject of global warming has been more predominantly brought to our attention. Is the threat of global warming real. Is it man-made or is this just a natural cycle of earth. Does it really affect earth’s inhabitants. Should action be taken against it. If so, what kind and to what extent. It cannot be only a coincidence that the alarmingly rapid climate change coincides perfectly with the increased amount of pollutants that humans release into the environment. The once stable climate has in recent years begun to skyrocket, thus altering the delicate structure of earthly life.... [tags: Global Warming Essay]

- Most scientists and environmentalists would say that humans are the main cause of global warming. In my opinion their theory of humans being the cause of climate change would be correct. Through out the history of the Earth the average global climate has risen and fallen, but because of humans the average global surface temperature has shot up by about 1.1 to 1.6 degrees Fahrenheit from the years 1906 to 2005. There indeed are many things that effect global warming such as; the sun and greenhouse gases, but the biggest thing that affects the Earth’s global climate change is humanity....

- Global Warming With it being the presidential election season the talk of global warming, also known as climate change has come up in conversation more. But should it be associated with whether you are republican or democrat. Global warming should not be rather you “believe” in because it is a stated fact. Many individuals do not know the correct definition and what global warming should mean to them. The definition by the Oxford Dictionary declares that 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, chlorofluorocarbons, and other pollutants (Oxford Dictiona...

- What is blue, green, and sustains an environment for living organisms to live. The answer is Earth; the planet of life where plants, animals, and humans breathe in the oxygen that comes from the atmosphere; knowing that we depend on oxygen to survive, preserving the atmosphere should be important enough to take care of it; sadly Earth is going through a global problem that is putting the atmosphere and the whole Earth in danger; that problem is called Global Warming. Global warming is used to describe increases in the average temperature of the Earth’s atmosphere and oceans; therefore this change is believed to be rapidly changing the Earth’s climate....

- Climate change is undoubtedly one of the most pressing threats we face today. A global issue, it is not confined to any single neighborhood of the globe; our entire planet is threatened by this menace. The overwhelming scientific consensus is that humans are causing the climate to warm by emitting immense amounts of greenhouse gases into the atmosphere. Global warming threatens to melt the ice caps, raise sea levels, and increase the potency and frequency of severe weather events. If immediate action is not taken the situation will only continue to deteriorate.... [tags: Carbon dioxide, Global warming, Emissions trading]

- It's no surprise to most people that the idea of global warming is a highly controversial and debated topic. But is there any real evidence that global warming is a growing problem or is global warming just a big scare tactic being used to get people to comply with strict government regulations. Global warming is widely believed to be the main cause of rising average global temperatures. In reality, global warming isn't really all what it has been exaggerated to be. Many of the predicted effects of global warming over time have actually been proven to be false all together.... [tags: Global Warming Essay]

- Scenario A: Continuing on Present Path Both climate change and global warming is one of the greatest environmental threats of our time, endangering our health, communities, the economy, and national security. These threats are responsible for rising seas, raging storms, increase of temperatures, aggressive fires, severe droughts, and floods from the effects of climate change and global warming. Climate change itself is the single biggest environmental and humanitarian crisis of our time. The Earth 's atmosphere is overloaded with heat-trapping carbon dioxide, which threatens large-scale disruptions in climate with devastating consequences.... [tags: Global warming, Air pollution]

- Are humans destroying the planet. Or is the planet going through a phase like it had thousands of years ago. Global Warming is a heated discussion to many scientists and politicians. Many facts may lead to believe that Global Warming is a threat. But, can it possibly be something that will benefit the planet in the long run. Global warming is becoming a problem to the Earth, but how do we justify this problem. Global Warming to some may be hard to explain and to go into detail with. "Global Warming is the theory that average temperatures around the world have begun to rise, and will continue to rise, due to an increase of certain gases, called greenhouse gases in the atmosphere."(Phillies E...

- The Global Warming and Environmental Changes, has a controversial issue that has been whether the facts support this as a real issue and that the worlds temperature is in fact warming or one of this being a myth and the planets overall temperatures are not raising any more or less than in any other time in history; therefore, for years this issue had been a scientific theory, nobody cared about except scientists. Since the 1970’s, the scientists discovered the fact that the temperature of the earth’s is increasing, and that the environment will encounter a real problem because of the humans’ activities on the earth....

- Investigating the Cause of Global Warming Many people disagree on the issue concerning global warming. Some believe that human activities, various forms of polluting, are the main cause of global warming. Others think that not only have humans not affected the planet by any significant amount, but that not much global warming has even occurred. Many scientists think that pollution is the cause of global warming and the greenhouse effect. There is a lot of evidence to support this theory. In the United States alone, almost 15,000 pounds of greenhouse gases are emitted per person each year.... [tags: Global Warming Climate Change]
