People around the world are adorning homes and businesses with festive holiday decor, which typically means an abundance of Christmas trees are on display. In the U.S., they pop up everywhere from the average living room to the Rockefeller Center plaza in Manhattan and the White House in Washington, D.C. But climate change threatens to complicate the tradition. Christmas trees, like any other crop, are affected by the general rise in temperature associated with global warming and the extreme weather events that result from it… Estimates from North Carolina State suggest upwards of 40,000 acres of land are dedicated to Christmas tree production statewide, with 5 or 6 million trees harvested annually for a collective retail value of $250 million or more.
