ScienceDaily: An ice core drilled at the Belukha glacier in the Siberian Altai by a Swiss-Russian research team under the leadership of the Paul Scherrer Institute (PSI) in 2001 has now provided new findings in climate research. Oxygen isotopes in the ice were used to reconstruct the temperatures in the Altai over the past 750 years. The scientists discovered a strong link between regional temperatures and the solar activity in the period 1250-1850, concluding that the sun was an important driver …
