Why California's Trees Keep Dying After Heatwaves End
Original: The Silent Canopy Collapse: Why California’s Trees Die After the Heatwave Ends
Reports highlight a phenomenon dubbed 'silent canopy collapse', in which California's trees die weeks or even months after a heatwave has passed, rather than during the extreme heat itself. Scientists explain that heat and drought damage accumulates in tissues and root systems, so trees succumb long after temperatures normalise. The slow, hidden nature of the decline has drawn attention to the long-term toll of repeated heat events on the state's forests and urban tree cover.
Why now: Unusual delayed tree mortality after heatwaves is an alarming and little-known consequence of extreme weather, prompting discussion among readers concerned about climate impacts.
