Forest fire activity in southern South America

Tree-ring fire scars from 1,767 trees in southern South America reveal a coupling of drought that is driven by the Southern Annular Mode--the north-south movement of winds that circle Antarctica--and regional fire activity at yearly and multidecadal timescales from 1665-1995, suggesting that under current and projected climate conditions in southern South America, SAM-mediated droughts are likely to drive widespread wildfire activity in the 21st century, according to a study.
