Measuring Techniques Improve–But the Implications Are Not Certain Evergreen trees at the edge of Alaska´s tundra are growing faster, suggesting that at least some forests may be adapting to a rapidly warming climate, says a new study. While forests elsewhere are thinning from wildfires, insect damage and droughts partially attributed to global warming, some white spruce trees in the far north of Alaska have grown more vigorously in the last hundred years, especially since...

Researchers with the University of Arizona (UA's) have discovered evidence of a formerly unknown, decades-long drought that occurred in the southwestern United States in the second century, the school announced in a November 3 press release. The study, which was the work of geoscientists Cody Routson, Connie Woodhouse and Jonathan Overpeck of the university's Laboratory of Tree-Ring Research, involved a study of the southern San Juan Mountains in Colorado. The region is said to be a...

A huge "migration" of trees has begun across much of the West due to global warming, insect attack, diseases and fire, and many tree species are projected to decline or die out in regions where they have been present for centuries, while others move in and replace them. In an enormous display of survival of the fittest, the forests of the future are taking a new shape. In a new report, scientists outline the impact that a changing climate will have on which tree species can survive, and...

US Forests Are Not Keeping Pace With Climate Change

More than half of eastern U.S. tree species examined in a massive new Duke University-led study aren't adapting to climate change as quickly or consistently as predicted. "Many models have suggested that trees will migrate rapidly to higher latitudes and elevations in response to warming temperatures, but evidence for a consistent, climate-driven northward migration is essentially absent in this large analysis," says James S. Clark, H.L. Blomquist Professor of Environment at Duke's...
