In a new study, physicist Philip J. Lloyd, a former researcher for the Intergovernmental Panel On Climate Change (IPCC), suggests global warming can’t necessarily be blamed entirely on greenhouse gases because 20 and 21st century temperature recordings lie within the standard deviation of natural warming. Via The Daily Caller’s Michael Bastasch, “Dr. Philip Lloyd, a South Africa-based physicist and climate researcher, examined ice core-based temperature data going back 8,000 years to gain perspective on the magnitude of global temperature changes over the 20th Century. What Lloyd found was that the standard deviation of the temperature over the last 8,000 years was about 0.98 degrees Celsius — higher than the 0.85 degrees climate scientists say the world has warmed over the last century.” According to Lloyd, “This suggests that while some portion of the temperature change observed in the 20th century was probably caused by greenhouse gases, there is a strong likelihood that the major portion was due to natural variations.” Kudos to Lloyd for, if nothing else, exercising an open mind. On the other hand, how much are his friends over at the IPCC willing to listen? Even though carbon dioxide levels continue to increase, having just recently surpassed 400 ppm, temperatures haven’t responded in tandem. In fact, temperatures have been flat for nearly 18 and a half years. Which begs the question that the UN still can’t rationally explain: Why are humans suddenly at fault?
