This question refers to the image in the previous question. Let's say that the amount of incoming short wavelength energy that gets reflected increases (for example if the Short Wavelength reflected in the diagram goes from -30 to -40). What would happen in the rest of the climate system? more long wavelength emitted at the Earth's surface, cooler global climate more short wavelength absorbed at the Earth's surface, warmer global climate less long wavelength emitted at the Earth's surface, warmer global climate less short wavelength absorbed at the Earth's surface, cooler global climate less short wavelength absorbed at the Earth's surface, cooler global climate Study the diagram below. In certain periods of Earth's history, continental configuration was such that a lot of atmospheric carbon dioxide (CO2) reacted with weathering rocks and then got stored in ocean sediments. As a result, the planet would get a lot cooler, as a lot of Greenhouse gases would be removed from the atmosphere and stored in rocks. According to the diagram below, how does "Earth's Thermostat" keep the Earth from plunging into a permanent icehouse? under cooler conditions, less evaporation happens, leading to more rain, leading to more weathering, leading to more carbon dioxide getting stored in rocks, and the Earth cools as a result under cooler conditions, less evaporation happens, leading to less rain, leading to more weathering, leading to more carbon dioxide getting stored in rocks, and the Earth warms as a result under cooler conditions, more evaporation happens, leading to less rain, leading to more weathering, leading to less carbon dioxide getting stored in rocks, and the Earth cools as a result under cooler conditions, less evaporation happens, leading to less rain, leading to less weathering, leading to less carbon dioxide getting stored in rocks, and the Earth warms as a result under cooler conditions, less evaporation happens, leading to less rain, leading to less weathering, leading to less carbon dioxide getting stored in rocks, and the Earth warms as a result For most of Phanerozoic earth history, average global climate was _______. cooler than today drier than today

rainier than today warmer than today warmer than today
