‼️ New paper! Cities are heating up, but smarter green spaces can help cool them down 🌳 Our new study shows how trees, coverage & better distribution of urban green spaces can significantly reduce heat and improve access!

Trees may not cool cities during heat waves as much as previously thought
A study found that the heat mitigation benefit of trees is significantly hampered in extremely hot conditions.
#Trees take precautions under heat stress to maintain moisture and avoid dryness by holding onto their sap. This reduces transpiration flow and thus their ability to cool—something overlooked in current climate forecasts.

Useful study on Sydney Science Park Summer Air and Soil Temperatures 2023-24. This establishes a microclimate baseline of air and soil temperatures at former open farming land in #Penrith Municipality in western Sydney. This area will be subject to residential development, but the data will allow the developer to implement 40% tree canopy and urban heat mitigation strategies using blue-green infrastructure, climate responsive design and cool materials.
Recommendations:
1. Develop and action robust environmental monitoring strategy
2. Make SSP a ‘Sponge City’ to assist plant growth and cooling
3. Harvest stormwater for plant irrigation
4. Support good plant growth, ameliorate existing soils and keep topsoils cool
5. Use structural cells for optimal tree growth
