- If there are many greenhouse gases, why is only carbon dioxide considered a cause of global warming?a. The other gases do not cause global warming.b. It isn’t. Scientists are concerned about other causes; for example, release of methane from melting permafrost could have significant effects on global warming.c. Other gases occur in such low quantities that they have little effect on the climate.d. Carbon dioxide is the only gas that absorbs long-wavelength infrared radiation.arrow_forwardWhich of the following statements about the carbon dioxide emitted to the atmosphere by human activities each year is most accurate? a. About half of it remains in the atmosphere and the other half is split equally between uptake by the oceans and vegetation. b. Nearly all of it remains in the atmosphere. c. About half of it dissolves in the oceans. d. On an annual basis, human-caused emissions of carbon dioxide are small compared to volcanic emissions. e. Human-caused emission of carbon dioxide is much greater than that emitted by respiration of all plants, animals, and microorganisms.arrow_forwardWhy does an urban park full of trees have a greater cooling effect than an equal-sized urban golf course covered in grass? Pick the BEST answer a) Because trees sequester carbon into their wood b) Because trees photosynthesize c) Because trees create temperature differentials that improve airflow d) Because trees transpire producing evaporative cooling and grass does notarrow_forward
