Meshing Opposing Methods of Climate Change Measurement

by Tyler Dean

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.

Altered Ecosystems by Strengthened Winds

by Jordan Aronowitz

Over the years, industrialization and urbanization have increased the amount of carbon dioxide and greenhouse gases present in our atmosphere. Obviously, these changes have affected the environment by increasing average temperatures and overall sea level, but surprisingly, climate change is also affecting wind levels. Over the past 25 years, many researchers have sought to determine whether these changes in wind speed positively or negatively effect related ecosystems. A 1990 hypothesis proposed that these winds are increasing and will positively affect the neighboring ecosystems. A synthesis of the data from experiments analyzing these patterns is the best way to see if the changes in these essential wind patterns have helped or harmed the ocean ecosystems under them. It was determined that these winds have been increasing overall, but further data must be collected to see their effects on the prosperity of the ocean ecosystems. Continue reading
