Global Warming

“Global warming is an increase in the earth's temperature due to fossil fuels, industries, agricultural processes caused by human activities, natural occurrences, and other gases.” The process of global warming is somewhat complex but often referred to as short-wave solar radiation sinking into the Earth's atmosphere and warming the earth’s surface; while long wave infrared radiation emitted by earth's surface is absorbed, and then re-emitted by traces of gas.

Climate changes that occur in our earth's atmosphere are primarily caused by a build-up of greenhouse gases. Greenhouse gases occur naturally in the environment; however human activity produces the largest amounts of greenhouse gases. There are many problems that can occur when high concentrations of greenhouse gases are present in our earth’s atmosphere. The number one problem is that greenhouse gases cause the earth to trap in more heat. When higher levels of heat are trapped inside the earth’s atmosphere it causes the overall average of the temperature to increase slowly over the years as more heat continues to be trapped. There are many misconceptions individuals have about global warming, for instance many individuals believe that pollution causes global warming, but in fact global warming is the result of burning fossil fuels, coal, and oil that release carbon dioxide. Another misconception is nuclear power causes climate change. Nuclear power actually reduces emissions of carbon dioxide when used in place of coal. Some individuals also believe that global warming only causes the earth’s temperature to increase. That statement is not entirely true; the name is misleading because in certain places the temperature will decrease and it will get colder. The majority of scientists around the world believe that global warming is a process underway and that it is human-induced.

The greenhouse gases that are responsible for global warming include; carbon dioxide, methane, and nitrous oxide. These gases occur naturally as part of the earth’s cycle. The Earth uses those gases to warm its surface. Carbon dioxide is released into the atmosphere when solid waste, fossil fuels, wood, and wood products are burned. Each greenhouse gas absorbs heat differently. If natural gases did not occur, then temperatures would be 91 degrees cooler than the current temperatures. These gases trap heat and cause the greenhouse effect, and rising global temperatures. Human activities are a large contributor to the levels of these ...
