Climate Change

Climate Change is the alterations of Earth's climate, which can have negative results that harm the environment. Various numbers of data has been found by the research of this subject. Dr. Milan Kovitch, A Serbian astrophysicist, came to the conclusion that climate change is connected to the orbital patterns of the earth; his data showed that changes in the earth's orbital patterns around the sun impact the amounts of solar energy on the planet, which can effect changes in temperature. Furthermore, studies of the changes in the chemical and physical properties of certain rocks has shown the changes of the Earth's climate. For example, a measure to determine whether climate change actually takes place is to examine sediment from the ocean: the chemistry of the shells of sediments can determine the history of Earth's temperatures. There is also some other data that has been collected on the numbers of glaciers on Earth, which have drastically decreased, thus alluding to the fact that climate change is happening rapidly. Plus, the levels of greenhouse gases (mainly carbon dioxide) in the atmosphere has gone up and has resulted in an increased temperature, which could be due to the amount of fossil fuels being emitted into Earth's atmosphere. Scientists such as Dr. Dan Shrag have explained the phenomen of climate change; Dr. Shrag suggests that although climate change has many negative effects on the environment, one major impact often overlooked is the increase of snow melt on mountain tops, which can negatively effect agriculture and our food supply. He continues to add that there might be other "surprises" from climate change since it's impossible to know every possible outcome. Considering the data that has been collected, some ideas about the future could include a much warmer climate or even drastic changes in natural disaster frequencies and intensities.

The following graphs represent the amounts of carbon dioxide compared to the United States and South Africa.

According to the data in these graphs, the United States gives off the most CO2 per person and overall. This could be due to the fact that the US uses much more fossil fuels than South Africa does. The differences in air pollution between countries is due to how developed a country is compared to another; more developed countries tend to have more fossil fuel usage and pollution because of their advanced technology, higher populations, and even their major use of factories. These fossil fuels pollute the air, which causes organisms to have a harder time getting oxygen, and agricultural practices greatly suffer. Because electricity is a major emitter of fossil fuels, the average person can help minimize climate change or air pollution by limiting their uses of electricity.
