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
Scientists have been trying to calculate the results of global warming by doubling and even tripling the Earth's global temperature. The only way they can gain these results is by the use of large computers, which take into account all environmental aspects of climate. Many of these computers have come up with results that vary greatly between one another. The computers are unable to determine a consensus on what will occur in the future; however, they have all determined that the Earth's global temperature will rise. Warming.
