A new analysis of more than 20,000 trees on five continents shows that old-growth trees are more drought tolerant than younger trees in the forest canopy and may be better able to withstand future climate extremes.
Our study published today in Nature Climate Change found climate change will put 90-100% of the trees and shrubs planted in Australian capital cities at risk by 2050. Without action, two-thirds of trees and shrubs in cities worldwide will be at potential risk from climate change.
Planting trees in cities is a climate solution that can absorb CO2 and keep urban areas cool. But these trees are also at risk.
More than half our urban trees are at risk as climate change heats up the planet - but there are ways to preserve them.
Researchers at Western Sydney University have found that over 1,000 tree species are at risk of exceeding their natural climate tolerance, including Queen Elizabeth's favourite oak.
