QUESTION 13 20 points 5 Read the following paragraph and then match each of 5 ideas proposed for reducing the level of greenhouse gases in the atmosphere to the corresponding effect on the organic carbon cycle it directly addresses Technology with the greatest potential to reduce greenhouse gas emissions already exists, say Princeton University scientists Stephen Pacala and Robert Socolow in a 2004 study published in the journal Science, Improving efficiency and conservation could slash billions of tons in atmospheric emissions of greenhouse gases each year. Improvements such as efficient engineering, better gas mileage and new fuel sources for vehicles and power plants have the potential to halt growth of emissions by around 2050, according to the study The scientists picked seven actions that they say could stabilize the climate by 2054. They focused on technology already in place that simply needs to be expanded - a lot Cars are an easy target. Each gallon of gas burned releases about 20 pounds of heat-trapping carbon dioxide into the atmosphere, according to the Environmental Protection Agency. That's a lot of carbon for the 2 billion cars that may be on the road by 2054, nearly four times the number today, the authors report The Science article suggests that doubling the average fuel efficiency of cars from 30 miles per gallon today to 60, switching to wind. gerforated hydrogen fuels or halving the annual number of miles traveled per car to 5,000 could slash carbon dioxide emissions. The savings would provide one-seventh of the total cuts needed to stabilize U.S. emissions, the article states Other such actions include replacing coal power plant capacity with natural gas, doubling nuclear power capacity to 700 gigawatts or adding 2 million wind turbines, about 50 times the current number Low-tech methods exist, too. Halting tropical deforestation by 2054, instead of having it. as well as reforesting about 965,255 square miles in the tropics would slash emissions by one-seventh, the Science article says. Better agriculture practices that slow erosion and reduce plowing would have the same effect, the article says. In addition, scientists are eyeing plenty of other technologies being developed to stabilize emissions. Burying carbon dioxide allows fossil fuel companies to continue pumping oil while mitigating greenhouse emissions. The United Nations estimates by 2050 it should be possible to store hall of cumulative global emissions in underground reservoirs at reasonable prices. The U.S. government already has launched a test project at a West Virginia coal power plant. The energy
company BP sends 1 million tons of carbon dioxide each year beneath the sands of the Sahara desert at one of its facilities in Algeria. These carbon sequestration projects sond millions of tons of carbon dioxide gas into underground geologic formations such as aquifors or gas beds now filed with water, natural gas or ol.
