This week’s readings had the common theme of global climate change. All of these sources encompassed different aspects of climate change. John Houghton’s “The Greenhouse Effect” was more factual and scientific. S. Goerge Philander’s “The Ozone Hole, A Cautionary Tale” was informational too, however, the piece also discussed global reactions to the rapid climate change. Thomas R. Karl and Kevin E. TrenBerth’s “Modern Global Climate Change”, focused on the intensity of anthropogenic influences of climate change and the dismal projection of the future. In “Stabilization Wedges: Solving the Climate Problem for the Next Fifty Years With Current Technologies”, Stephen Pacala and Robert Socolow went in

Lastly, the outer part of this “blanket” is colder than the inner part, which helps keep the Earth warmer than it would be otherwise.
S. Goerge Philander’s “The Ozone Hole, A Cautionary Tale” describes the stages in discovering the ozone hole and the global reactions involving the ozone layer. Philander begins by examining CFCs and the history behind their discovery. When CFCs where first introduced, they were seen as a wonderful invention by mankind. He later goes on to discuss all of the different uses of the CFCs. But before delving into the topic of the effect of CFCs on the environment, Philander goes onto discussing why there is such an abundance of Ozone in the stratosphere and gives a scientific breakdown of what ozone is and how ozone, in its unperturbed, natural state, is working in a continuous feedback loop. Afterwards, this reading brings the attention back to how the once glorious CFCs were beginning to be seen as a threat to the ozone layer. There was a major reaction to this possible consequence in the 1980s. Sales of common CFC products plummeted and companies agreed to negotiate for an international agreement to ban these harsh chemicals. The main point of this tale shows how nature responds to tiny changes to the atmosphere and how there can be success in scientific predictions and global diplomatic reactions.
