  The Holocene Climate of the Antarctic Peninsula Reference Yoon, H.I., Park, B.-K., Kim, Y. and Kang, C.Y.  2002.  Glaciomarine sedimentation and its paleoclimatic implications on the Antarctic Peninsula shelf over the last 15,000 years.  Palaeogeography, Palaeoclimatology, Palaeoecology 185: 235-254. What was doneThe authors analyzed data pertaining to several "sedimentological, geochemical and micropalaeontological parameters" extracted from radiocarbon-dated sediment cores that were retrieved from the Antarctic Peninsula's western continental shelf. What was learnedDeglaciation of the outer shelf commenced prior to 15,000 years before present (BP); but a return to colder conditions occurred between 12,800 and 11,600 years BP, "coincident with...

  Do Changes in the Sun's Brightness Affect Earth's Climate? Reference Pang, K.D. and Yau, K.K.  2002.  Ancient observations link changes in sun's brightness and earth's clilmate.  EOS, Transactions, American Geophysical Union 83: 481, 489-490. What was doneThe authors assembled and analyzed a vast amount of data pertaining to phenomena that have been reliably linked to variations in solar activity, including frequencies of sunspot and aurora sightings, the abundance of carbon-14 in the rings of long-lived trees, and the amount of beryllium-10 in the annual ice layers of polar ice cores.  In the case of sunspot sightings, the authors...
