Climate change is making North American forests more vulnerable to insects and disease but is helping some trees grow faster and increase their resistance to pests, a team of researchers from Dartmouth University said Monday.
Researchers reviewed almost 500 scientific studies dating back to the 1950s to produce what they called the most comprehensive review of the affect of climate change on the forests that cover about one-third of North America. The effort was undertaken as part of the National Climate
The researchers said that warmer temperatures and increased carbon dioxide in the atmosphere are boosting tree growth, which could have a positive impact on economies that depend on timber and wood pulp, and could help pull carbon out of the ecosystem.
