Global Warming: Fact Or Fiction? Global warming has always been a controversial issue. There are few skeptics, but those who are believe that these changes are a natural part of the earth’s climate cycles and variations, and that we shouldn’t try to stop them. However, many scientists and advocates of climate change know that ocean disruptions, extreme weather events, record temperatures, retreating glaciers and consequently rising sea levels are all examples of global, incontrovertible evidence that climate change is not only happening, but is not entirely a natural occurrence. The term greenhouse gases is often referred to, but few know the meaning or significance in relation to global warming. The sun is our source of light and heat, and is what has made life on this earth possible. The sun radiates heat and light in the form of light waves, which essentially would turn the earth to rock had it not been for the layers of protection outside our planet (Gore). The atmospheric layer contains a delicate balance of many essential gases and molecules that reflect the sun’s radiation and keep our world optimal temperature for life (Suzuki,1). (See image 1). Carbon dioxide (CO2), nitrous oxide, hydrofluorocarbons, perfluorocarbons, slupher hexafluoride and methane are the six main Rancourt 2 naturally occurring gases in our atmosphere. Ozone, a molecule made up of three oxygen atoms (O3) lies in our stratospheric layer (Mungall and McLaren, 19) and absorbs lethal, ultraviolet radiation. Put simply, without this little molecule, there would be no human race. However, what scientists all over the world have come to realize, in short, is that we are mindlessly and irreversibly throwing away our only chance at survival. Mankind disperses over fifty thousand unnaturally occurring compounds into our atmosphere, and the result? Chaos. Since the start of the industrial era, methane –a previously mentioned atmospheric gas—has doubled in concentration (Lerner an Lerner, 259). CO2 –another atmospheric gas—has risen thirty-two percent (Suzuki, 1) In the last six hundred fifty thousand years, the CO2 level has never gone above three hundred ppm (Gore). It has now. The atmospheric layer (including ozone) is not absorbing enough heat, and as a result, the earth is absorbing that heat, creating a global warming. Since 1900, the average global temperature has risen 0.6 °C (Suzuki, 1). It may not seem like a lot, but the earth is warmer than it has been in the last one thousand years. (See image 2) Chlorofluorocarbons (CFC’s) are one of the many compounds we release. CFC’s are found in things like aerosol sprays and appliances. They are also responsible for the growing hole in the ozone over the Arctic (Mungall and McLaren, 19-23). Ironically enough, the part of our world that keeps out heat is diminishing over one of the coldest places on the planet. Perhaps if the same scenario had happened in an already temperate location, the Rancourt 3 results would have been more dramatic and people would start to understand that the world is changing, and in no small part to us. However, there are dramatic consequences of these CFC’s. New data from an Arctic climate research project shows that there is forty percent less sea ice near the pole than in 1976 (Mungall and McLaren, 17), only 37 years ago. (See image 3). A research project that started only forty years ago shows that Arctic ice-caps are thinning at a rate of almost one percent each year (Barr, 18), which means that in sixty-seventy years, there will be no more Arctic ice-caps. In 1969, Dr. Roy Koerner, a Canadian government glaciologist, crossed the Arctic ocean from Alaska, to the North Pole, to Norway by…
Global warming is one of the biggest social topics of our time. In addition, it is one of the most hotly contested. Nearly everyone believes in the greenhouse effect, which basically means that the sun's warmth is trapped in the Earth's atmosphere by the Earth's natural gasses such as: methane, ozone, carbon dioxide, nitrous oxide, water vapor, and chlorofluorocarbons. Without the greenhouse effect, we would not be able to live on Earth because it would be too cold. The concept of global warming…
Global Warming Facts
From rising sea level to increasing frequency of hurricanes - the evidence exists in plenty. Surprisingly though, we are trying our best to turn a blind eye towards the fact that Earth is getting warmer, and this warming is threatening our basic existence. The evidence mentioned below are perhaps the best possible examples to claim that global warming is happening and it's going to affect us sooner or later.
The increasing number of hurricanes is perhaps…
Global Warming: Fact or Fiction?
Global Warming, The Greenhouse Effect, is a very controversial topic in our society, and both sides are backed by political parties/politicians. The idea is based upon our emissions into the atmosphere, creating a hole in the o-zone, allowing more sun in and in turn heating up the earth. The greenhouse effect, in itself has some logic to it, but there is no factual evidence or proof that can relate it to an increased surface temperature on earth. Man-made…
Climate Change: Fact or Fiction?
Central Carolina Technical College
December 1 2013
Climate Change is a term often used in place of the term “Global Warming”. This is the first place the general population errs. Climate change refers to a change in the earth’s natural state; it includes global warming, but also includes, global cooling, the changes in precipitation, changes in the atmosphere, land masses and oceans and also changes in storm frequency…
Global Warming: True or False?
Global warming, most of us have a general idea of what it is but I’m going explain it in a little more detail. In a nutshell, it’s the steady rising of Earth’s temperature. What’s causing this is greenhouse gases plus the greenhouse effect. The greenhouse effect is what happens when certain gases like carbon dioxide, methane, nitrous oxide and water vapour trap heat. These gases let in light but keep heat from escaping, causing the Earth to warm. The amount of greenhouse…
Global warming: Fact or Fiction?
“The warnings about climate change have been extremely clear for a long time. We are facing a global climate crisis. It is deepening. We are entering a period of consequence.”
Global Warming is possibly the scariest thing to be happening to our earth, and people are oblivious to it. The evidence is there to prove it, carbon emission levels are higher than ever, due to pollution all over the world. The atmosphere is now thicker, due to…
Global warming - A threat to our very existence
Global warming has been described as the biggest environmental threat facing humanity. It is indeed a very complex phenomenon. In the simplest of terms it is an increase in the average temperature of the Earth. From ozone depletion to hurricanes, global warming has various hazardous effects on our lives.
Tornadoes rip through the heart of downtown Los Angeles, leaving thousands dead and destroying countless homes and apartment blocks. In New York…

Specific purpose: To convince my audience that global warming does exist and we can help put a stop to it.
I. What would you do if someone tells you that the foundation of your home is sinking? Would you try and fix it or would you let it sink slowly?
II. Today, I am going to help you recognize that global warming does exist, we are the main cause and we can do something to stop this.
III. It is important we all know this because before we know…
