Group 4: Wedges

The wedges are a good idea in general, but they are not entirely realistic. In order to accomplish Pielke's climate change mitigation goals, each wedge would have to be accomplished. This is highly unrealistic, because it would be difficult to get every country to agree to and enforce these wedges. Many of these wedges, such as the wedges pertaining to CCS, would require a lot of scientific advancement that would be difficult to achieve. Additionally, some wedges like #14 are completely unrealistic: it is nearly impossible to stop all deforestation.
While many of these wedges are unrealistic, our group identified a few that could possibly be accomplished and be beneficial for the planet. #3 (cutting electricity use by 25%) is possible to achieve and would save a lot of energy and money. We also liked #10 (displacing coal power with wind power) and #11 (displacing coal power with solar power). Certain countries and regions are already starting to use more wind and solar power. It would be expensive for some areas to adopt these new technologies, but they would overall be beneficial in cutting emissions.

Ocean acidification is important because it impacts biodiversity. A falling ph level has detrimental impacts on species that build shells or skeleton based on carbonate. For example, tropical corals. Hence ocean acidification destroys ecosystems, resulting in the ultimate disappearance of certain species. The computer generated evidence predicts that if the carbon dioxide emissions continue to rise exponentially, this will result in the drastic increase in the ocean ph level. The levels of PH are predicted to rise as much as they have in the past 300 million years in the next 1000 years. The computer models used past historical and geographical evidence to see what the natural rise would be and compared it to the rate at which ph levels are rising today. It would be difficult for nature to compensate for these damages. Consequently, resulting in further reduction on the marine biodiversity, specifically, coral reefs.

Group 5: We misidentified the metal as Iron, when it is in fact Zinc. This occurred because we calculated the volume incorrectly which thereby translated to the wrong density. In addition, we observed that the metal did not melt. Our metal also fell apart onto the table which could have been a sign of possible meltage. As for our mineral, we believed that it was quartz, when it was actually Fluorite. We did not believe it had dissolved into the test tube; however, it in fact was slightly soluble. The largest error we made, which would have helped us determine correctly what the quartz and the metal were, was incorrectly calculating the density. If we would have done this part correctly, we likely would have determined the correct mystery materials.
