Greater drought intensity and frequency before AD 1200 in the Northern Great Plains, USA
Article Abstract:
Lake salinity fluctuations indicate that intense droughts occurred frequently before AD 1200 in the Northern Great Plain (NGP) region of central North America. The intensities and frequencies of drought in the last 2300 years in the NGP is reconstructed using the Moon Lake salinity fluctuations as inferred from fossil diatom assemblages. These droughts continued for centuries and those during AD 200-370, AD 700-850 and AD 1000-1200 were the extreme ones. The low salinity after AD 1200 indicates that this period had been wetter and cooler than the preceding years.

Rainfall and drought in equatorial east Africa during the past 1,100 years
Article Abstract:
A decade-scale reconstruction of rainfall and drought in equatorial east Africa during the past 1,100 years is presented, based on lake-level and salinity fluctuations of Lake Naivasha.It is found that equatorial east Africa has alternated between contrasting climate conditions, and strong chronological links are found between the reconstructed history of natural long-term rainfall variation and the pre-colonial cultural history of east Africa.
