CLIMATE CHANGE OBJECTIVES 1) Know what happens to the amount of radiation emitted and the wavelength of maximum output from a body as its temperature increases or decreases. Radiation increases at temperature increases. As temperature goes up, wavelength goes down. 2) What part of the EMR spectrum is the maximum output of the Sun, and what part of the EMR spectrum is the maximum output of the Earth? Visible radiation. Earth – thermal infared. 3) What are the six major climate change triggers? Variations in solar input. Milankovitch cycles. Elevation and distribution of continents. Ocean interactions. Atmospheric composition change. Biological and physical feedback mechanisms. 4) What is the principle reason that the surface of Venus is so much hotter than the surface of Earth? 96% CO2 in atmosphere. 5) What is the “faint young sun” paradox, and what mechanism might resolve this paradox? The mechanism is hydrolysis. 6) Does solar output correlate with pre-industrial global temperature, and can it be used to explain the recently observed warming? 7) How could cosmic ray influx cause climate change, and can in be used to explain
