| Zusammenfassung |
| Using six long-term temperature proxy data series derived from different
natural evidences, including pollens and lake-sediments, we reconstructed a
temperature series with a 100-yr time resolution for the past 5000 yr in the
Hetao region and its surrounding areas. The resulting series suggests that,
on a millennial timescale, temperatures in the region were higher than the
mean value of the whole series during the 5000~2600 years before
present (yr BP) period, and became relatively low comparing with the average
temperature of the whole series after 2600 yr BP. Within these two periods,
temperature fluctuations comprising numerous short, multi-centennial
intervals also existed. A comparison between our reconstructed series and
other series in China and across the Northern Hemisphere indicate that, on a
long-term scale, cold–warm variations had been in phase across the whole
hemisphere during the past 5000 years; on the century to multi-century
scale, the beginning and the ending times varied from region to region, thus
implying that climate changes did not occur simultaneously in different
regions. |
