  1. The 3 Milankovitch cycles
  2. ice cores
  3. perihelion
  4. biogeography
  5. West Pacific Warm Pool
  1. a ice that is drilled out of glaciers. Gas bubbles in them give a direct measurement of what the climate was like in the past
  2. b Precession, obliquity, and eccentricity
  3. c located near the equator-where water is warmer in the west Pacific than the east Pacific
  4. d where plants and animals do and don't live now and in the past
  5. e the closest orbital point to the sun (147 million km)

  2. Thermohaline Circulationair pressure 'flips' between Australia (W) and Tahiti (E)


  3. eccentricitythe average surface condition over some period of time


  4. obliquitythe average surface condition over some period of time


  5. negative feedbackWhen A increases, B increases, which causes A to increase even more.Ex. temp increase, ice melts, albedo decrease, temp increase
