A debate whether global warming is a real threat or an imagined one.
The paper presents facts supporting the theory that global warming is occurring and it then presents facts indicating that global warming is only a perception. The paper analyzes these facts and concludes that the evidence does suggest that global warming is a threat.
“One of the main pieces of evidence global warming is based on is a rise in surface temperature over the last twenty years. The evidence for global warming according to Justus and Fletcher is based on the temperatures from 1980 to 2000, with 12 of these years being the warmest years “since historical records have been kept.” While this may initially seem like significant evidence, closer analysis shows one major problem. The phrase “since historical records have been kept” suggests that these twenty years are being compared to a long length of time. However, in reality, these temperature records only refer to around a century of data.”
