Carbon dioxide (CO₂) is one of the so-called greenhouse gases. These gases hold heat energy in the atmosphere, which raises the overall temperature of the Earth. This helps maintain the Earth's biosphere, but also has led to environmental concerns. The more CO₂ in the atmosphere, the higher the Earth's average temperature will be. What is another way in which human activity is increasing the amount of atmospheric CO₂, and what are potential global effects of these changes in CO, levels?

How did the failure of the Michelson-Morley experiment change scientific theories of light? A. The Michelson-Morley experiment provided a new theory that fit the data better than the theory of the luminiferous ether did. B. The Michelson-Morley experiment proved that the luminiferous ether moved at the exact same speed as the Earth during all seasons of the year. C. The results of the Michelson-Morley experiment had to be rejected because the theory of the luminiferous ether was so well established. D. The results of the Michelson-Morley experiment did not fit the theory of the luminiferous ether, so the theory had to be rejected.
