Questions and Answers
What is the heat island effect?
The heat island effect refers to urban areas being up to 2.5 degrees hotter than surrounding areas due to human activity.
How are cities looking to adapt to different temperatures and extreme weather events?
Cities are looking at ways to adapt by changing the design of buildings to reduce heat and help them cool down more quickly, such as using trees, lighter-colored rooftops, and thicker walls.
According to Richard Bellingham, what are some interesting examples around the world of adapting to different temperatures and extreme weather events?
Richard Bellingham, Director of the Institute for Future Cities at the University of Strathclyde, mentioned examples such as trees, lighter-colored rooftops, and thicker walls as ways to adapt to different temperatures and extreme weather events.

Study Notes
Urban Population Trends
- Over half of the global population, approximately more than 3.5 billion people, live in urban areas.
- In the developing world, urban populations are projected to increase by 2.5 billion over the next 30 years.
Heat Island Effect
- Urban areas often experience the heat island effect, making them up to 2.5 degrees Celsius hotter than surrounding rural areas due to human activities.
- This temperature difference is exacerbated by global weather changes, presenting challenges for urban planning and infrastructure.
Adaptation Strategies
- Cities are exploring various strategies to adapt to rising temperatures and extreme weather events.
- Richard Bellingham, Director of the Institute for Future Cities, emphasizes innovative design solutions in urban environments.
Building Design Innovations
- Design modifications will be necessary to combat heat in urban buildings, such as:
- Utilizing lighter-colored rooftops to reflect sunlight.
- Implementing thicker walls to insulate against heat.
- Installing windows that minimize heat absorption.
- Incorporating green walls and roofs with vegetation to enhance cooling.
Case Study: New York
- Over the last nine years, New York has been implementing various methods to address urban heat and enhance climate resilience.
