Urban Heat Islands (UHI)
As part of The Climate in Our Hands – Climate Models guidebook, “Urban Heat Islands” (UHI) is an interactive lesson that helps students explore the phenomenon of urban heat islands and investigate adaptation strategies to reduce extreme heat in cities. Using a multimedia animation, students experiment with different cooling solutions and analyze their long-term effectiveness.
What is this activity about?
This lesson introduces students to the urban heat island effect, which causes cities to be significantly warmer than surrounding rural areas due to human activities and infrastructure. By modeling mitigation and adaptation strategies, students learn how urban planning and climate action can shape the future of city climates.
Key Information
Subjects: Physics, Natural Sciences, Geography
Duration: Two sessions of 1h30 each (or one selected session) + 20 min wrap-up
Teaching method: Documentary analysis and multimedia animation
Key learning outcomes:
Understand the urban heat island effect and its causes
Differentiate between mitigation and adaptation solutions
Explore the concept of maladaptation (solutions that lose effectiveness over time)
Connect climate action with the Sustainable Development Goals (SDGs)
Develop systems thinking, a crucial sustainability competency
How does it work?
Session 1: Limiting Global Warming to 1.5°C (1h30)
Introduction to the UHI Animation (25 min): Students familiarize themselves with an interactive tool that models climate and temperature changes in cities.
Scenario Testing (55 min):
Students work in small groups to test climate mitigation strategies and attempt to keep global warming below 1.5°C by 2100.
They analyze the feasibility, costs, and ethical implications of different strategies.
Wrap-up Discussion (10 min): Students reflect on why systemic transformations are needed across multiple sectors to meet climate goals.
Session 2: Local Adaptation Strategies (1h30)
Understanding the UHI Effect (45 min):
Students conduct a brainstorming session on why cities are hotter than rural areas.
Using the animation, they test different urban adaptation solutions (e.g., green roofs, urban planning, cooling systems).
Evaluating Solutions for 2100 (45 min):
Students predict how their chosen solutions will perform in the future.
They identify maladaptations, such as cooling solutions that lose effectiveness due to climate change.
They assess the connection between urban heat mitigation and climate action goals.
Final Reflection (20 min):
Students compare local adaptation solutions and global mitigation strategies.
They discuss the role of urban planning in shaping future climates.
