How has the Global Temperature of the Earth and the United States Changed over the Last 100 Years?

According to the Intergovernmental Panel on Climate Change, temperatures have increased roughly 1.53 degrees Fahrenheit (.85 degrees Celsius) in the 132 year span from 1880 to 2012. In the northern hemisphere, the warmest 30-year period of the last 1400 years is the three decades from 1983 to 2012 (Marsis, 2015). In the chart to the right, if one is to follow the blue line, they can see the long term increase in temperature starting from 1880. It is also evident in the chart that the biggest increase and warmest years are from 1980 to present, which was mentioned in the statement above. Despite some slight differences in research and calculations between distinguished groups such as NASA, NCDC, and the University of East Anglia, they all agree that the decade of the last 15 years has been the warmest since modern records have been kept from over 100 years. In the 134 year record, the warmest 10 years in history have all been since 2000, with the warmest year on record being 2014. The year 1998, however, does not fit that statement which seems to be the one main exception (“Global Temperature,” 2015). Looking more closely at the United States, the warming rate for the country is about 1.3 degrees Fahrenheit in the last 100 years. The decade as a whole from 2000-2009 was the nation’s warmest on record. The average temperature during that span was 54.0 degrees Fahrenheit,…
