Description :
The analysis suggests that since the Holocene there had been 5 periods when the temperature was below the present with 4 periods of relatively high temperature. The five cold periods occurred 10,300-9,500| 9,500-7,500| 4000| 3000| and 2,000-1,650 years before the present with warm periods inbetween. Temperature varied between 3 of present average and precipitation during the warm periods may be 200-600 mm higher than at present. (TNC).
