Global Warming Paper Cameron Conolly
For years many people have believed that we are causing the Earth to warm up faster. Global Warming is the heating of the climate. Others believe it is due to natural climate processes. Either way, we know that Global Warming is a serious issue for our Earth.
One of the reasons we think Global Warming is occurring is because of Orbital Variations. “Orbital Variations” is part of a theory developed by Milutin Milkankovic. An astonishing fact about Milankovic was that he worked on this theory while a prisoner of war in World War I. In this theory Milankovic suggests that variations in axial tilt, precession, and eccentricity of Earth’s orbit determine Earth’s climate. Axial tilt is the variation of the angle of Earth’s tilt. Obliquity is a term that describes axial tilt as well. The tilt, measured in degrees, can vary from 22 to 24.5 over a period of 41,000 years. Increased Obliquity can cause summers to be warmer and winters to be colder. Decreased Obliquity can cause summers to be colder and warmer winters. As you can see in graph 1, every 41 years the climate goes through a series of changes. This is why some people think the Earth is going to get very hot very soon.
Precession is a change in the orientation of the rotational axis of a rotating body. For example, the star Polaris is the North Star, but in 13,000 years the Precession of the rotation of Earth’s axis means that it will not be directly north. This will cause the Earth to warm up also.
Orbital Eccentricity is also a factor. Eccentricity is the measurement of how stretched out the orbit pattern is. If the Orbital Eccentricity varies, we could be warming up much faster.
Some people claim that humans are to blame for Global Warming. Deforestation is a popular topic that Global Warming activists are bringing to people’s attention. Plants and trees

Global Warming Global Warming has become quite an alarming issue in the past decade. Although most people don’t find it directly affecting their everyday lives. This is the reason not much is being done about it. Some people are in complete denial of this phenomenon, while others are positive it is happening. I personally, believe global warming is happening. My argument is to prove global warming exists. It exists because of society’s everyday habits to use natural resources at an increasing rate…

Global Warming Global warming has practically been the number one topic of discussion in today’s scientific research. What is global warming? Global warming is an increase in the average temperature in the earth’s atmosphere. For many years now, there have been discussions on whether global warming is caused by man-made carbon dioxide or natural greenhouse gases. Many scientists believe that man-made carbon dioxide is not the cause of global warming but there are some that…

Lonna Carlisle GOVT 2305 S26 Global Warming Research Paper There is one thing that all people have in common, and that is that we all must live on this Earth. There is not one single person, group or nationality that can escape that truth, at least not yet. Mother Earth, as we call this beautiful planet that is our home, is completely irreplaceable and no amount of money can buy us a new one. We as humans are utterly stuck here, so the Earth's health and climate should be paramount to everyone…

Nowadays, in many countries, there are many problems about environment. Global warming on the earth is becoming more serious. This essay will discuss the causes and effects of global warming. One of the main causes of global warming is carbon dioxide emissions. My point is about the way people pollute the environment. All human activities in real life such as using cars, burning fuel result in increasing carbon dioxide emissions. Because carbon dioxide emissions comes from the burning of gasoline…

Thesis: Global warming is a very complex issue in terms of science and economics. Some believe that Global warming is the beginning of the end of the world. While others believe that it is completely a hoax. I personally believe that Global warming is over-hyped. It is just another example of the media getting a hold of something and blowing it out of proportion. Despite your personal views of Global Warming one fact can’t be argued, which is that the government is spending a lot of money related…
