Help students trace climate impacts from physical changes to consequences for people and ecosystems.
This module connects warming with melting land ice, thermal expansion and sea-level rise, then follows the effects through ecosystems and human livelihoods. Students examine feedbacks and linked impacts, including food insecurity, so their explanations show how one change can lead to another.
Learning covered
- Explain how melting land ice and thermal expansion raise sea level.
- Distinguish the effects of melting land ice and floating sea ice.
- Explain the ice-albedo feedback.
- Connect ocean warming with changes to marine ecosystems.
- Trace impacts through food supplies and people’s livelihoods.
- Develop linked geographical explanations using evidence.
Teaching options and materials
Choose between the tiered Full Lesson presentation and the focused Essentials presentation. Matching materials include the Full Lesson workbook in colour, black and white and a version for typed responses, plus completed and student-notes Essentials Booklets with black-and-white alternatives. Exam practice, a mark scheme, a short assessment and a START HERE guide are included.
The Impact Web
Teams combine hexagons into a web of impacts. Students take responsibility for ice, oceans, ecosystems or people and write a causal explanation on each shared edge. They identify the feedback loop, test what happens when one hexagon is removed and trace a path through the web as the basis of an extended answer. The collaborative lesson has its own presentation and printable pack.
Designed for ages 14–16 and Cambridge IGCSE Geography 0460 climate change topics. Supplied as PowerPoint and Word files, plus a PDF guide. Text and tasks can be adapted; illustrations are embedded images.
