In 2015, delegates from 196 nations met in Paris to negotiate a deal that would reduce emissions of greenhouse gases and prevent Earth from warning by more than 2Â°C before 2100. The resulting agreement, called the Paris Accord, contains a pledge by each country to limit emissions by 2035. The pledges differ between developing countries and developed countries. A public document lists the specific pledge made by each country. To comply with the pledge made by the USA, President Obama signed the Clean Power Act, which would put his country on a course to reduce its emissions by 40% before 2035. People objecting to this act filed a lawsuit in the United States, arguing that President Obama abused his executive power. The Supreme Court heard the case and decided that each state could determine the rules by which it contributes its fair share of reductions.

Use this information and your knowledge about biology to answer questions 35-40.

36. Since pledges to reduce emissions appeared in a public document, each country was more likely to pledge a fair share of reductions. True or False

37 More developed countries, such as the USA, can fairly argue for the right to make fewer reductions, because these countries have a higher standard of living to maintain. True or False

38 If each state in the USA had the option to reduce emissions, most states would reduce emissions by their fair share without any regulation by the federal government. True or False

39 A tragedy of the commons will occur if the US fails to honor its pledge and other countries respond by abandoning their pledges. True or False

40 To be effective, the Clean Power Act would likely need to penalize corporations that refuse to shift toward cleaner sources of energy. True or False

Global Warming: Carbon Dioxide and its Effects on Agriculture Many scientists understand that earth is getting warmer and that the cause could be an intensified greenhouse effect resulting from increased CO2 emissions from industry, vehicles, and the burning of forests. Increased carbon dioxide levels will also affect the nutritional quality of many crop plants by decreasing protein content and increasing weed growth. Global warming could influence agriculture and perhaps even completely melt polar ice, leading to flooding of coastal regions. Over 90% of scientists now agree that global warming is occurring. In response to this potential threat, several European countries, the United States, Australia, and New Zealand have made a commitment to significantly reduce carbon dioxide emissions. However, some countries oppose taking strong actions at this time and the U.S. has only met a relatively small proportion of its commitments. Several reasons are cited. First, some experts think the apparent warming trend may be just a random fluctuation in temperature. Second, if the temperature increase is real, some argue that it has yet to be proven that the cause is increased CO2. However, regardless of the effects on climate change, the carbon fertilization effect of increased CO2 levels is affecting crops each year. Some believe it would be difficult to cut CO2 emissions without sacrificing comfort, convenience, and economic growth. Carbon Dioxide as a Greenhouse Gas: http://www.epa.gov/climatechange/ghgemissions/gases/co2.html Effects of Carbon Fertilization of Crop Plants: http://www.news.ucdavis.edu/search/news_detail.lasso?id=9479 http://news.illinois.edu/news/14/0507CO2_AndrewLeakey.html http://news.heartland.org/newspaper-article/2013/10/29/carbon-dioxide-emissions-stimulating-15-trillion-crop-production Please consider and reply to the questions below: Do you think we should have more evidence that greenhouse warming is real before taking action? Or is it better to play it safe and act now to reduce CO2 emissions? The evidence of carbon fertilization of crop plants is readily available and accepted. Crop plants are producing less seed and less protein. Weed plants are overgrowing crop plants and reducing annual yields. Should we take action now to reduce CO2 emissions in order to prevent the loss of agricultural output and nutritious crops?
