Document Summary
March 4th, 2015: how long does it take big climate change to happen, gisp2 - dansgaard/oeschger d/o events, really abrupt events across the globe. B. 1. particularly in the north atlantic: what caused these abrupt changes. C. 1. b) bipolar seesaw north warms when south cools and vice versa, during these abrupt cli- mate changes (c. 1. b. 1) ocean conveyor turing on and off. C. 1. c) rainfall south of the equator was also a mirror image of greenland climate. C. 2. wind bels and tropical rainfall band (itcz) seesawed toward the warmer hemi- sphere over dansgaard/oeschger cycles. Nh will probably warm faster than sh in 21st century due to more land and arctic ice albedo feedback. : the younger dryas. D. 1. the most recent of these abrupt changes it was a return to near ice age condi- tions in greenland for 100 years as the ice age was ending. Caused by rerouting of continental drainage from the mississippi to st lawrence river as ice sheet retreated.
