Climate variability has an opposing impact on marine life and tree growth
The same climatic drivers that enhance upwelling of nutrient-rich ocean waters and support of marine productivity can result in lower precipitation on land and slower tree-growth. Tree-ring chronologies helped to explain how upwelling was happening during the past 600 years. This was outlined in a recent study published in Science by an international team of scientists including David Frank of the Swiss Federal Research Institute WSL and the University of Bern's Oeschger Center.Read more at: http://phys.org/news/2014-11-climate-variability-opposing-impact-marine.html#jCp
