A new study on Greenland ice cores shows that Arctic sea ice loss in the period 30-100,000 years ago was associated with major oscillations in high latitude climate. During this period, Greenland temperatures repeatedly increased by up to 16°C in less than a century, followed by more gradual cooling. The results are published today (Monday …

Gol-e-Zard Cave lies in the shadow of Mount Damavand, which at more than 5,000 metres dominates the landscape of northern Iran. In this cave, stalagmites and stalactites are growing slowly over millennia and preserve in them clues about past climate events. Changes in stalagmite chemistry from this cave have now linked the collapse of the …
