Urban areas are generally 1–3°C hotter than surrounding countryside due to the urban heat island effect, which can be as severe as 7°C in some cities. A study analyzing data from nearly 9,000 cities found that urban trees significantly mitigate this heat, reducing temperatures by approximately 0.5–1.5°C. Trees provide natural cooling through shade and transpiration, but their distribution is often unequal, with wealthier neighborhoods having more trees. Lower-income areas, which lack tree cover, experience higher temperatures, highlighting a disparity in access to natural cooling. While trees are vital, they can only offset about 10% of the additional heat expected due to climate change, increasing to 20% with extensive planting. Therefore, a broader strategy is essential, incorporating reflective materials, green spaces, and improved airflow, alongside reducing greenhouse gas emissions to effectively combat rising urban temperatures.
