Trees are advancing into the Arctic tundra and retreating from boreal forests further south, where stunting and die-offs are expected
Forests from the Arctic to the Amazon are transforming at a “shocking” rate due to the climate crisis, with trees advancing into previously barren tundra in the north while dying off from escalating heat farther south, scientists have found.
Global heating, along with changes in soils, wind and available nutrients, is rapidly changing the composition of forests, making them far less resilient and prone to diseases, according to a series of studies that have analyzed the health of trees in north and South America.
