Melissa McHale emphasizes the importance of collaboration, stating, 'I think all of the answers exist right on our doorsteps, and we just have to work together to make it happen.' This suggests that local solutions and community efforts are essential in addressing urban heat challenges.
Sandeep Agrawal explains how urban areas contribute to higher temperatures, saying, 'Much of this higher temperature is because of the fact that urban areas tend to have surfaces like concrete and asphalt. They absorb a lot of solar energy, and then they release it in the air over time.' This highlights the material impact of city infrastructure.
Agrawal's findings indicate a significant temperature disparity, stating, 'urban areas were often six to 12 degrees hotter than rural areas, with the highest urban heat islands in Toronto and Vancouver.' This puts the scale of urban heat island effect into perspective.
He advocates for green infrastructure, suggesting, 'there needs to be more trees which absorb heat over time, and less concrete.' This points to practical solutions for mitigating urban heat.
