Global Warming is a major concern to anybody who understands the threat it poses to our society. Recently many ideas have been discussed about ways to stop or slow down the process of Global Warming. Global Warming is the term used to describe a gradual increase in the average temperature of the Earth’s atmosphere and its oceans. It is a process that is believed to be permanently changing the Earth’s climate.(1) In this essay I will explain what global warming is, how it is caused and its effects on the earth.

Global climate change has already had observable effects on the environment. Glaciers have shrunk, ice on rivers and the lakes are breaking up. Earlier plant and animal ranges have shifted and trees are flowering sooner. Effects that scientists had predicted in the past and would result from global climate change, are now occurring. There is a loss of sea ice, accelerated sea level rise and longer more intense heat waves.(3) Each of the past 37 years has been warmer than the 20th century average. The twelve warmest years on record have all occurred since 1998. The hottest year ever recorded for the contiguous United States occurred in 2012. Globally, the average surface temperature has increased more than one degree Fahrenheit since the late 1800’s. Most of that increase has occurred over just the past three decades. Scientists have high confidence that global temperatures will continue to rise for
