Rapid link between North Atlantic climate and East Asian monsoon 8200 years ago
An abrupt cold snap lasting more than 100 years was identified in the North Atlantic area 8200 years ago, probably caused by flooding from an ice-dammed lake in North America. Using an annually-laminated stalagmite from a cave in China, a team of researchers from China University of Geosciences, Oxford University and University of California have now established that this event was rapidly transmitted through the atmosphere and caused a dry period in central China that lasted 150 years. This highlights that the two regions are intimately linked in warm climates similar to today’s. The results of this research was published in the latest issue of the journal Nature Geoscience.
