Mountain guide Eduardo Zuniga stands by an ancient spruce in Fulufjallet, southern Sweden, October 4, 2012. On a windswept Swedish mountain, a 10,000-year-old spruce with a claim to be the world's oldest tree is getting a new lease of life thanks to global warming, even as many plants are struggling. At a range of latitudes, but especially in the far north, climate change is bringing bigger than expected swings, putting billions of dollars at stake in a push to develop varieties with resilience to frost and heatwaves, drought or flood.
