Lab: Facts: Atmosphere,Albedo,solar energy Greenhouse gas: A gas that absorbs and re-emits infrared light (increase) Global climate change= global warming visible light from sun, then infrared light to greenhouse gases which moves slowly, 50F cooler people often lack knowledge of Global climate change Lecture: Why do certain gasses cause the greenhouse effect? Co2 was changed all the time, Solar Radiation (Sun), Volcanic activity, human impacts Albedo Effect, feedback lop, The reflectivily of a surface; how much radiation is reflected vs. absorbed Color has a major influence on albedo A high albedo means something is more reflective, a low albedo means it is less reflective/ will absorb more radiation Albedo=1--->completely reflects radiation Antarctica now has more than. 65,000 meltwater lakes' as summer ice melts Since grass leaves release water vapor (or transpire) What effect does this have on the albedo across the entire planet? How migh...
