Scientists emphasize the urgent need for increased tree planting in urban areas to mitigate rising temperatures and combat the effects of climate change. Research from Cardiff University indicates that trees can lower city temperatures by up to 5°C (9°F). Alongside trees, solutions like breezeways, water features, and curved buildings can also help.
Professor Philip Jones highlighted that achieving a tree coverage of 30-40% could significantly cool urban environments. Current coverage in cities like Cardiff and Newport is low, with Newport aiming for a 25% increase by planting an additional 30,000 trees over ten years.
Efforts like these are crucial as urban heat islands pose greater risks to city dwellers, leading to increased heat stress, particularly during heat waves. Trees provide shade and increase humidity through evapotranspiration, enhancing urban comfort.
Successful models from cities like Singapore, which boasts extensive greenery and innovative designs, show the potential of urban planning combined with vegetation. Immediate action is recommended to begin planting more trees, as they are cost-effective yet take time to mature, making prompt efforts essential for future climates.
