Document Summary
China and coal: coal is most polluting of fossil fuels. Asian brown cloud: asia formed 3km thick layer of pollution hanging over south. Asia: reduce sunlight by 10-20, alter monsoon rains, decrease rice productivity by 5-10, speed melting of himalayan glaciers; dark soot deposited absorbing sunlight, premature deaths, government now provides subsidies, ef cient electric space heaters to replace dirty coal stoves. Atmosphere consists of: 78% nitrogen, 21% oxygen, 1% argon gas. Variable gases: vary in concentration from time to place. Atmosphere is layered: atmosphere is 1% of earth"s diameter, troposphere: bottom most layer. Provides us with air + responsible for weather. Thin: 11km high: mass: 75% of mass of total atmosphere bc air is denser near earth"s surface. Temperature: -57*c at highest point in troposphere: warmest since heated by earth: absorb and reradiate solar energy to troposphere. Environmental lapse rate: rate of temperature decrease with height. Tropopause: where temperature stops declining with altitude: stratosphere: 2nd layer.
