Global Warming:
Two Sides To Every Story

“Global warming is the increase in the average measured temperature of the Earth's near-surface air and oceans since the mid-20th century, and its projected continuation.” -Wikipedia (11)

There are always two sides to every story and every different point of view has a right to be heard. When it comes to the discussion of global warming there are two very distinct points of view. The world seems to be split between global warming being caused by humans and it being a natural occurrence. This paper will discuss the two views in depth, followed by my opinion about the global warming phenomena.

Global Warming:
A Natural Occurrence

What would happen if tomorrow we were told that the Earth is flat? It would probably be the most important piece of news in the media and would generate a lot of debate on weather it was true or not. So why is it that when scientists who have studied the global warming phenomenon for years say that humans are not the cause nobody listens? Global warming is not due to human contribution of Carbon Dioxide (CO2). This in fact is the greatest deception in the history of science. In fact, global warming is a natural occurrence that cannot be stopped; as humans all we can do is slow down this occurrence.

The first reason is because global warming comes and goes. The earth naturally heats up and cools down. Thirty years ago we thought the biggest threat was global cooling and now the biggest threat is global warming. Through out history there has been numerous cooling and warming periods and we are now going though on of those natural warming periods. We also experienced a warming period during the Medieval Warm Period around 1100 AD when Vikings settled into Greenland because it used to be green and the perfect place to grow crops (1); grapes suitable for winemaking were also reported growing in England (2); and the tree line in Scandinavia was 100–200 m higher than present (3). This warming period was followed by a cooling period called the Little Ice Age from 1400 to 1850 AD that brought severe winters and cold summers to Europe (1). Today we are enjoying global temperatures, which have warmed back to levels of the Medieval Warm Period; this means there is an ice age in our near future. The cycle of global warming and cooling has been happening long before humans have occupied the Earth and will continue to happen long after we are gone; it’s a nature cycle that cannot be broken.

The second reason why global warming is a natural occurrence is because the sun is what warms the earth. When the sun gets hotter, it stands to reason that we get hotter too and this goes vise versa. If the sun is cooler, we get cooler. The sun has several cycles and the main one we see is the 11-year cycle. “Every 11 years, the Sun moves through a period of fewer, smaller sunspots, prominences, and flares - called a solar minimum - and a period of more, larger sunspots, prominences and flares - called a solar maximum" (4). Right now we are currently at the minimum of this cycle, so the sun is in the process of increasing its heat output and we will experience a peak of heat in 2012 (5). When the sun gets hotter there are more rays heating the earth, so the earth gets hotter. If we are so positive that global warming is a man made problem, explain why Mars is also warming at the same pace as the earth is. “In 2005 data from NASA's Mars Global Surveyor and Odyssey missions revealed that the carbon dioxide "ice caps" near Mars's south pole had been diminishing for three summers in a row” (6). Like Earth, Mars has also experienced warming and cooling periods throughout its history. The changes in the sun's heat output can account for almost all the climate changes we see on Earth and Mars; manmade greenhouse warming has made only a small contribution to the warming happening on Earth.

The third reason why global warming is a natural occurrence is because...
