Climate change of the last millennium inferred from borehole temperatures:regional patterns of climatic changes in the Czech Republic - Part III

Accurate temperature-depth profiles may help to assess the temperature vari ations associated with the climate changes in the past. Ninety-eight ground surface temperature histories inverted from the temperature-depth borehole logs drilled on the territory of the Czech Republic [Bodri, L., Cermak, V. , 1995. Climate changes of the last millennium inferred from borehole tempe ratures: results from the Czech Republic - Part I. Global Planet. Change 11 , pp. 111-125; Bodri, L., Cermak, V.: 1997. Climate changes of the last two millennia inferred from borehole temperatures: results from the Czech Repu blic Part II. Global Planet. Change 14, pp. 163-173.] are used to reconstru ct the regional patterns of the respective climate change. The climate was mapped for the following periods: 1100-1300 A.D. (Little Climatic Optimum), 1400-1500 A.D., 1600-1700 A.D. (main phase of the Little Ice Age), and for the most recent climate trend after year 1960. Comparison of the obtained maps with the meteorological observations and proxy climatic reconstruction s confirmed good applicability of the ''geothermal'' paleoclimatic reconstr uctions for the regional studies.
