Natural Phenomenon
The global warming subject has been a heated debate for the past few decades. Some scientists are saying this is a completely man made problem. There are two clear sides to this subject and both have evidence, but the evidence is stronger on that global warming is just Mother Nature at work. The government has poured hundreds of millions of tax payer dollars into research for manmade global warming. The theory is that humans are causing the “greenhouse effect” and putting too much carbon dioxide into the atmosphere. There is clear evidence to prove otherwise and that the carbon dioxide emissions have a much smaller affect than the scientists, government, and media make you believe. Manmade global warming is not occurring. Global warming is a natural occurring process that the earth goes through over the years.

The earth has been heating and cooling for hundreds of thousands of years and it’s a natural climate change. The Pleistocene Ice Age occurred 18,000 years ago and put most of the earth under a sheet of ice (Hieb). Ever since then the earth has gone through seven major warming and cooling trends. Of the six trends preceding the current period of warming, three produced temperatures warmer than the average 59˚F today and three have produced cooler temperatures. In 1650, the temperature of the earth plummeted to a low 57˚F, the coldest point since the ice age. This is why from 1650 to 1850 is known as the Little Ice Age. Our global warming of 1.5˚F since 1850 is simply a recovery of the Little Ice Age. Even the United Nation Intergovernmental Panel on Climate Change (IPCC) concludes that, “some of the global warming could be a recovery from the Little Ice Age rather than a direct result of human activity” (Brogan).

The two periods in history when the planet was significantly warmer than today were followed by bountiful harvests and economic prosperity. Between 6500 B.C. and 3500 B.C., the temperature rose to 62°F, which is three degrees warmer than today. This is the temperature that greenhouse theory scientists say will be the temperature by 2100 and which will supposedly wreak havoc on the environment. However, it was during this time that the Agricultural Revolution began, laying the foundation for civilization. Between 900 A.D. and 1100 A.D., when the temperature rose to 61°F, Europe experienced record harvests and economic prosperity (Brogan). These changes are caused by a constant fluctuation in the earth’s climate.

The earth’s warming can all be explained by the sun’s activity. The most recent global warming scare was from 1850 to 1940. This time of warming was obviously not created by human’s emissions of carbon dioxide (Wigmore). The earth absorbs solar radiation and heat from the sun. This process is something that we cannot control. There are many other things that are causing the earth to warm that are also out of our control.

Several processes and things on earth release carbon dioxide into the air and cause warming. Like said before the earth absorbs solar radiation and heat and rises the temperature on the surface of the earth. Processes that release carbon dioxide into the air include volcanic eruptions, decaying of plants and animals, and even us simply breathing. Humans and animals release carbon dioxide from breathing. Humans do put carbon dioxide into the air through running cars and factories, but the emissions are minimal compared to the other things that cause this. The release of carbon dioxide into the air cause something called the “greenhouse effect” which environmentalists say is ruining our atmosphere.

The greenhouse effect is one of the most important things that our earth entails. It keeps the earth warm and without it the earth would be about 10˚F. The basic idea of it is that the sun hits the earth and warms the earth. The warm earth then emits infrared radiation to cool itself. The radiation is absorbed by the greenhouse gases in the atmosphere. It’s...
