More evidence that the MWP & LIA were not European phenomena. A study by two South African scientists, Tyson & Lindesay, in 1992, entitled “The climate of the last 2000 years in southern Africa” finds evidence of both in Southern Africa.
Until recently, relatively little was known of the exact nature of climatic change in southern Africa over the past two millennia. New research based on oxygen isotope analyses of cave speleothems and mollusc remains in shell middens, together with foraminifera studies of inshore marine deposits, palynological and micromammalian research and earlier dendrochronological work, has allowed more reliable identification of the effects of the ‘Little Ice Age’ in the subcontinent. Cooling prevailed from 1300 to 1850 with a warm episode occurring between about 1500 and 1675. In addition, the generally warmer period from about 900 to 1300 may have been associated with…

So I was interested to stumble across an announcement issued by Purdue University in August 2012, which strongly confirmed the reality of the phenomenon. Purdue has applied for a patent for the use of this effect as a means to supply advance warning of…
