Scottish cave offers evidence of ancient climate variations

1 post in this topic

SYDNEY, June 15 (UPI) -- A series of stalagmites in a Scottish cave have offered scientists a window back in time, revealing ancient climate variations that may have precipitated historical and societal changes in Europe.

"Our research provides a climate context for some of the big human migration events in Europe and allows us to start building hypotheses about the impact of environment on societal change," lead researcher Andy Baker, a professor at the University of New South Wales, explained in a press release.


By measuring the different limestone formations in Roaring Cave -- a small cave covered by a layer of peat in northwest Scotland -- researchers were able to plot changing precipitation patterns. Prolonged periods of heavy rainfall corresponded with accelerated stalagmite growth.
