Cities worldwide are implementing tree-planting programs to mitigate climate change, emphasizing the importance of selecting appropriate tree species and providing adequate water, as seen in the case of damaged trees in Penrith, Western Sydney due to extreme heat and drought.

• Street trees face challenges in surviving climate change.
• Many governments are investing in tree-planting programs for urban cooling.
• The selection of tree species and provision of sufficient water are crucial for their survival in a warmer world.
• Extreme heat and drought can damage urban trees, especially exotic deciduous species.
• Some tree species showed resilience to heat and drought, while others suffered crown dieback.
