The study warns that rising atmospheric dryness could significantly reduce the cooling effects of forests, particularly in regions already vulnerable to heat stress. This could exacerbate local temperature increases, impacting ecosystems, agriculture, and human health. Urban areas, which rely on green spaces for temperature regulation, may face heightened risks as the cooling capacity of vegetation diminishes. Additionally, the reduced ability of forests to mitigate heat could accelerate climate change feedback loops, further intensifying global warming.
