What can trees tell us about climate change?

2015-11-08 16:58:00| Climate Ark Climate Change & Global Warming Newsfeed

Christian Science Monitor: Trees dont just provide the paper for history books. They actually write the historical records themselves. Tree-rings, new layers of wood added to a growing tree each year, record climatic data annually throughout a trees life. Ancient trees provide a record of drought, rainfall, and other climatic variations. And that record could help scientists better understand current and future climate trends. Dendrochronologist Edward R. Cook and his team at the Lamont-Doherty Earth Observatory of...

More rain leads to fewer trees in the African savanna

2015-10-19 21:02:00| Climate Ark Climate Change & Global Warming Newsfeed

ScienceDaily: In 2011, satellite images of the African savannas revealed a mystery: these rolling grasslands, with their heavy rainfalls and spells of drought, were home to significantly fewer trees than researchers had expected. Scientists supposed that the ecosystem's high annual precipitation would result in greater tree growth. Yet a 2011 study found that the more instances of heavy rainfall a savanna received, the fewer trees it had. To this ecological riddle, Princeton University researchers might have...
