35% of northern tree-fungi partnerships negatively impacted by climate change, particularly affecting pine trees in North America.

A PNAS study reveals climate change is disrupting tree-fungi relationships, particularly in northern regions. As climate shifts, 35% of tree-fungi partnerships are negatively impacted, with pine trees being most at risk in North America. Trees form relationships with mycorrhizal fungi that supply crucial nutrients in exchange for carbon. These relationships are vital for tree survival and underpin all life on Earth.
