Question
President Camacho named Mr. Igno Ramos, an oil tycoon, director of the Environmental Protection Agency. Mr. Ramos is deciding whether to cut funding for climate change research. Your job is to bring him up to speed on the subject. Here are some statements you may be making to help him understand:
31. Mr. Ramos, _____ is not a greenhouse gas.
32. Mr. Ramos, ______ produce(s) CO2.
33. Mr. Ramos, one way to address increases in atmospheric CO2 is to increase C sequestration in soil organic matter. This is how it works:
34. Mr. Ramos, ______ can be a sink for a greenhouse gas.
35. Mr. Ramos, soil microbial processes that produce greenhouse gases include ______.
36. Mr. Ramos, N2O and CH4 in the stratosphere have one thing in common – they are ______.
37. Mr. Ramos, the permafrost in parts of Canada and Russia has thawed as a result of warmer temperatures, which has resulted in an increase in the flux of ______.
38. Mr. Ramos, of the gases in Q. 37, _______ has a higher warming potential.
39. Mr. Ramos, based on what we know about the effects of soil moisture and temperature on soil processes, we would expect more frequent soil saturation and an increase in soil temperature of 5oC to _______ the flux of CH4 in poorly drained soils in the northeastern US. 6
40. Mr. Ramos, based on what we know about the effects of soil moisture and temperature on soil microbial processes, we would expect more frequent soil saturation and an increase in soil temperature of 5oC to ______ the flux of N2O in an agricultural soil receiving inorganic N fertilizer in the northeastern US.
41. Mr. Ramos, based on what we know about the effects of soil moisture and temperature on soil processes, we would you expect more frequent soil saturation and an increase in soil temperature of 5oC and shorter winters to ______ weathering of parent material into soil in the northeastern U.S.:
A. Increase B. Decrease C. Have no effect
Explanation / Answer
31. Mr. Ramos, _____ is not a greenhouse gas.
Answer: oxygen is not a greenhouse gas or sulfur dioxide is not a greenhouse gas.
32. Mr. Ramos, ______ produce(s) CO2
Answer: Burning fossil fuels
Burning fossil fuels produce carbon dioxide.
33. Mr. Ramos, one way to address increases in atmospheric CO2 is to increase C sequestration in soil organic matter. This is how it works:
Answer: If Co2 increase in atmosphere then Co2 plant respiration and Co2 soil respiration will be increases, and decompose of those planets may be increase carbon sequestration in soil organic matter.
34. Mr. Ramos, ______ can be a sink for a greenhouse gas
Answer: May be carbon dioxide can be sink for a greenhouse gas.
