Anthropogenic Global Warming

Several hypotheses have emerged to explain the global warming phenomenon. Among these theories, Anthropogenic Global Warming (AGW) has emerged as the leading theory, which deduces that the Earth is warming due to human activity and that as a result humans will eventually destroy the planet. The AGW theory has permeated nearly every facet of modern society. Over the past few decades, scientists, politicians, marketers, and Earth lovers alike, for various reasons, have employed propaganda techniques to promote the Anthropogenic Global Warming theory; in the process, they proactively sought to curtail the exposure of the truth in order to profit from people’s apprehension of global warming.
Fears of the Earth’s rising temperature are based on global temperature averages over the past 100 years, with special interest placed on the past decade. During the mid 1800’s, the average surface temperature varied but, was close to -.4 °C. Contrasting the older temperatures with today’s average of .4°C, a difference of nearly .8° C, has alarmed many and caused others to investigate the reasons for the perceived increase in temperature.
