Now it’s been discovered that climate change may eventually kill off the oyamel fir trees that the butterflies cling to during the winter.
In The Independent, Steven Connor quotes researchers Karen Oberhauser and Townsend Peterson as saying that, “?When current oyamel distribution was included in models to be projected to future climates, none of the present wintering sites was predicted to be suitable in 50 years’ time.”
