Drought is the key contributor to Aspen tree death in Colorado, according Colorado Public Radio reporter Grace Hoodmar. “A Carnegie-led team of scientists looked more closely at the relationship. Key to the study is how the lack of water damages the vascular system in aspens, which transports water throughout the tree.”
Princeton University researcher William Anderegg, co-author of the study states “One really key finding of this is that the clock is ticking on these forests. A lot of control rests in our hands,"
"If we act to address climate change early, we can prevent and avoid some of the massive die offs that seem to be coming down the pipeline,” he said.
