Old growth forests provide exceptional carbon storage; sheltering them from harm is a top priority. Old trees are more tolerant to drought than younger ones, scientists have found, and could provide a buffer against climate change. Researchers studied 22,000 upper-canopy trees from across the globe. Looking at tree-ring data to see how droughts had affected their growth. Other studies have shown old forests are irreplaceable habitats for biodiversity. Watch to know more about the importance of old growth forests for tackling climate change.
