Ancient high-altitude trees grow faster as temperatures rise Increasing temperatures at high altitudes are fueling the post-1950 growth spurt seen in bristlecone pines, the world's oldest trees, according to new research. Pines close to treeline have wider annual growth rings for the period from 1951 to 2000 than for the previous 3,700 years, reports a University of Arizona-led research team. Regional temperatures have increased, particularly at high elevations, during the same 50-year...

 Pine trees grown for 12 years in air one-and-a-half times richer in carbon dioxide than today's levels produced twice as many seeds of at least as good a quality as those growing under normal conditions, a Duke University-led research team reported Monday (Aug. 3) at a national ecology conference.Carbon dioxide readings that high are expected everywhere by mid-century. The findings suggest some woody tree species could, in the future, out-compete grasses and other herbaceous plants that...

Scientists fear that the swarms of mountain pine beetles that have killed more than half of all lodge pole pines in British Columbia may eventually make their way into forests in the US. And while cold winters typically kill most of the beetle larvae, the region has recently witnessed unusually higher temperatures that have allowed the beetle to thrive for longer periods of time. The beetle has recently been found in Alberta, and scientists told BBC News that they could threaten jack pine...
