Mass forest die-offs will proliferate and expand. The trend toward more extreme heat waves and droughts is lethal for forests.
At the current pace of warming, much of the world will be inhospitable to forests as we know them within decades. The extinction of some tree species by direct or indirect action of drought and high temperatures is certain. And some recent research suggests that, in 40 years, none of the trees alive today will be able to survive the projected climate, Brodribb said.
