Recent Climate Warming: Surface Air Temperature Series and Geothermal Evidence

摘要: Long-term (1961 – 1996) meteorological air temperature series together with the reconstructed ground surface histories, obtained by inverting borehole temperature-depth profiles, were used to project regional patterns of recent (climate) warming rate on territory Czech Republic. The characteristic magnitude 0.02 –0.03 K/yr was confirmed results several years monitoring in two experimental boreholes. shallow temperatures at depths about 30 –40 m, i.e. below reach seasonal variations, can serve as an alternative tool direct quantitative assessment present rate. data also seem sustain a potential man-made component contributing more pronounced observed areas large agglomeration.
