Document Summary
Thursday, week 9, lecture #16 , class #18. Term projects: connect environmental geology and societal challenge. Memo due this week: center around the recommendation. Elevator pitch: slide due (tuesday) at 5pm day before. Types or handwritten responses due at beginning of class. Weather: atmospheric conditions during specific time interval at given location. Co2 can absorb much of the radiation traveling from earth to. Space and so increases the temperature in the atmosphere. Traps energy that is trying to leave the earth-- the greenhouse effect. Amount in last 100 yrs has rapidly increased-- unnatural. Global average temperatures have been increasing -- changes processes/consequences on surface of the earth. Even with low level emissions, substantial warming. Most warming at north and south poles, Melting ice shelves (sea ice extent is expect to vanish) Next 100 yrs: at least meter, 1-2 meters would cover portions of land where 20% of population lives. Rising sea levels seen as threat to coastal (flat lying) u. s.
