More evidence is emerging that if not reversed or slowed, climate change will kill off most or all of the trees in Joshua Tree National Park, which is 180 miles south of Las Vegas, in the next 80 years.
Scientists at the University of California Riverside said the die-off is already beginning.
UCR botany professor Lynn Sweet was the lead researcher in the new study published in the journal, Ecosphere.
She said the killing off of the trees can be slowed or stopped, but a very small window remains for that to happen.
