If you've traveled to a forested national park out West in recent years, you may have noticed two things. First, a growing number of lodgepole pine trees are dying, victims of the bark beetle. And secondly, atmospheric haze, caused in part by tiny solid particles suspended in the air, is becoming a problem. A new study shows these two phenomena may be related, tied together by chemistry and climate change factors.
