Here's a 30-minute revision video on climate change for GCSE Geography.
This revision video tests your knowledge and understanding of climate change, which is part of The Challenge of Natural Hazards unit on Paper 1 (AQA GCSE Geography).
It includes evidence of climate change, human and natural causes, the greenhouse effect, impacts and mitigation/adaptation - all covered through a series of interactive quizzes and activities, with a bit of explanation thrown in.
