As air rises in the atmosphere, its temperature drops, even if no heat flows out of it. (a) Based on what you learned in Sections 4.4 and 5.3, explain why this is so. (b) Cumulus clouds form when rising air is cooled to the point where water droplets form because of condensation. Why are these clouds usually much higher above the ground in dry climates than in wet ones?
(a) Calculate the power per square meter reaching Earth's upper atmosphere from the Sun. (Take the power output of the Sun to be 4.001026 W.) (b) Part of this is absorbed and reflected by the atmosphere, so that a maximum of 1.30 kW/m2 reaches Earth's surface. Calculate the area in km 2 of solar energy collectors needed to replace an electric power plant that generates 750 MW if the collectors convert an average of 2.00% of the maximum power into electricity. (This small conversion efficiency is due to the devices themselves, and the fact that the sun is directly overhead only briefly.) With the same assumptions, what area would be needed to meet the United States' energy needs (1.051020J) ? Australia's energy needs (5.41018J) ? China's energy needs (6.31019J) ? (These energy consumption values are from 2006.)

Climate change represents a global threat to the prosperity and security of humans and other species. An added element of uncertainty regarding Earth's climate future has to do with feedback loops in the climate system. One positive feedback is associated with the loss of glaciers, sea ice, and snow pack. Ice reflects about 90% of the radiant energy incident upon it, so the polar ice caps reflect significant amounts of solar energy. As the planet warms and surface ice is lost, the Earth becomes less reflective, absorbs more energy from the sun and thus heats up more rapidly. A negative climate feedback is associated with the amount of energy that Earth loses to space. As the planet warms the Stefan-Boltzmann law indicates that it will radiate more energy. Earth's average surface temperature over the 20th century was 56.7F. Since 1880 the average temperature of Earth has increased by about .830 degrees C. What is the fractional increase in power radiated away by the planet in 2021…
