Global warming - Research Paper Example By definition, global warming refers to the average increase in air temperature of the globes surface and ocean. This increase has been estimated to have started in 1950. A term used as a synonym for global warming is climate change. According to facts it is a clear and unmistakable fact that the earths temperature is rising. Global warming is not just about two different summer seasons, but it involves changes occurring on the environment, weather and atmosphere. It is thought interms of decades and not seasons. The term global warming can be misleading as it can be wrongly thought to mean that thing are going to be hotter, yet in some cases situations are stormier, drier, or colder.

The earth has experienced the 12 warmest years ever in history with 2012 being the hottest year ever recorded in the United States. The average surface temperature increase has been over one degree Fahrenheit from 1800s with the last three decades being the worst (Union of Concerned Scientists, 2014).

As projected by scientists, temperatures are expected to increase by an average of 2-11.5 degrees Fahrenheit’s by the end o f 21st century (Trimarchi 2014). As stated by Environmental protection Agency, the earth’s temperature is a balance between the suns heat that leaves and the amountstays on the planet. The earth becomes warm when it absorbs heat from the sun and it is made cooler when the suns heat is reflected back. A lot of factors are responsible for earth’s energy balance, some of which include variation in the green house
