Climate ChangeCurrent LectureI. Systems 1: Environment and Society a. The global movement of air that transports heat and moisture and explains the climates of different regions is called atmospheric circulation b. System: a set of elements linked together so that changes in one element often result in changes in another c. Key systemsi. Climateii. Colonialismiii. Imperialismiv. Capitalism d. Weather: the temperature and precipitation at a given place and timee. Rotation around sun creates relative temperatures of hot and cold II. Climate: typical weather conditions at a given location a. Things to know:i. Definitions of the tropicsii. ICTZiii. Subtropical highiv. Jet streams v. Orographic precipitation b. Climate system: interactions of air, water, sun,i. “the climate system makes places globally interconnected yet locally differentiated”ii. Interaction of multiple earth systemsiii. Relationship of interdependenceIII. Environmental hazards: physiographic qualities and events that transform ecosystems often withpotential to threaten human life a. Earthquakes, hurricanes, floods, fires, volcanoes, tsunamis b. Mitigating environmental hazards: Dams, seawalls, fighting forest firesThese notes represent a detailed interpretation of the professor’s lecture. GradeBuddy is best used as a supplement to your own notes, not as a substitute.c. Human activity (social, political, economic) influences threat such hazards posei. Increase/decrease vulnerability to hazards, exacerbate risks IV. Climate changea. Human causes: greenhouse gasses, carbon dioxide emissions, water vapor, aerosolsb. Natural causes: glaciers, volcanoes, tectonicsc. Anthropocene: geological era defined by dominant human impact on the planetd. Sustainability: ability to meet current and future human needs while preserving environmental resources,
