Global Warming
Global warming is a huge environmental and economic challenge that we are facing in the 21st century. Global warming is also commonly referred to as the greenhouse effect. Global warming can affect entire ecosystems and climates, which in turn affect the way in which people live. We in our lifetimes will not be around to see the major outcome of global warming; however, it is still a major concern. It has come to be known that the major increase in temperature over the last century is a result of the Industrial Revolution. During the Industrial Revolution, when new machines were being used, there were major increases in carbon dioxide levels in the atmosphere, which is one of the main causes of the greenhouse effect. This is the main reason that scientists believe the temperature increase is the effect of humans rather than a climate change. Over the course of the past century, the Earth s global temperature has risen by about one degree Fahrenheit. This may not seem like a large increase, but given the time period in which this increase occurred, the change is quite amazing. Some scientists argue that this one-degree increase is just the Earth s natural changing climate, but others believe that it is due to global warming. More and more scientists are becoming convinced of global warming and its dangers. Global warming is a phenomenon that occurs when fossil fuels are burned and greenhouse gasses are ejected into the atmosphere and burn ozone; the shield that reflects ultra violet rays from the sun. Global warming doesn t just affect the temperature; it also affects all aspects of climate and weather. The most common belief of global warming is that the temperature increase is in direct variation with the increase of carbon dioxide in the atmosphere. The affects of global warming will develop slowly over a long period of time. The Earth itself warms as well as its temperature. As the temperature increases, the sea level rises, and precipitation...
