Conspiracy theorist is a derogatory term used to discredit critical thinkers. University of Wisconsin English professor and scientific skeptic Robert Blaskiewicz states that the term was â€Å"invented and deployed by the CIA in the 1960s to discredit those who dared to question the Warren Commission and expose covert activities†. (Blaskiewicz) Despite of this, Critical thinkers have brought about today’s technology into existence. It is also important to remember that anyone who expresses their opinion is not always correct. Being able to refine these ideas and not let them metastasize is a part of analytical thinking. Today’s world is full of these contradicting ideas of what is right, and what is wrong. One of the many ideas today, is the†¦show more content†¦Temperatures in the atmosphere have been continuing to rise, above the average temperature of 42.6 degrees Fahrenheit. The global average temperature is stable over long periods of time. The eff ects of the global climate shift lead to observable damage. For instance, more powerful weather patterns and sea ice has been breaking up. By the end of the century, temperatures could rise as much as one degree Fahrenheit. This increase is unusual in the Earth’s climate record. Small variations in temperature correspond to extreme changes in the environment. For example, at the end of the last ice age, when the Northeast United States was covered by more than 3,000 feet of ice, average temperatures were only 5 to 9 degrees colder than today. (NASA) What are the factors that are contributing to this change? Changes in climate are attributed to human factors and have imputed the shift in global temperature. Climate change is a continued threat to society. 97% of Climate scientist agree the leading cause of the current global warming trend is human activity and the greenhouse effect. (Union of Concerned Scientist) Warming that results when the gases in the atmosphere trap hea t radiating from Earth’s surface toward space. Over the last hundred year’s human development has changed the natural greenhouse. Clearing of land for
