Laramie, WY – About 45 fires are burning across the West right now, and some scientists think they may be an early sign of climate change. Ecologist Steve Jackson at the University of Wyoming says wildfires have been burning hotter and earlier in recent years. "This really could be human-caused climate change knocking on the door and tell us that it's here," he said. "And it could be a few years or even decades before we can really tease out all the causes," he added.
Jackson says, over the last few decades, springtime has happened earlier in the West. That has dried out the land faster and made it more susceptible to fire.
