Camille Parmesan and Gary Yohe describe the reasoning and results of the IPCC’s method of measuring the fingerprint of climate change. Their goal was to “improve communication, provide common ground for discussion, and give a comprehensive summary of the evidence.” The IPCC’s method mitigates the result abnormality from the opposing methods and views of biologists and economists by implementing both of their techniques into IPCC’s. The need for the IPCC’s approach comes from both of the existing results being beneficial, but flawed to the point that citizens, readers and policy makers must remain dubious of the results. Economists focus on direct evidence, in the moment and apply time discounting in order to account for their lack of quality control. From this, they conclude that climate change is only important if it is responsible for the current biotic changes; which leads economists to the conclusion that climate change’s fingerprint is weak.
