3.4 Continual Climate Change
Explain natural and enhanced climate change, evaluate evidence and compare consequences in contrasting places.
How to study WJEC GCSE Geography
Move from place and process to mapped or numerical evidence, explain inter-relationships across scale, and finish with a supported geographical judgement.
Core concepts
Concept 1
3.4.1 Milankovitch cycles, sunspots, volcanic eruptions, glacials and interglacials
Exam cue: Confirm the current WJEC unit, numbered content area, geographical scale, named context and assessment form before selecting evidence.
Concept 2
3.4.2 Greenhouse gases, natural greenhouse effect and human enhancement through energy, land use, farming, waste and industry
Exam cue: Separate natural long-term drivers from recent human enhancement and connect each evidence type to the climate variable it supports.
Concept 3
3.4.3 Ice cores, tree rings, IPCC/NASA indicators, Keeling curve, ice retreat and sea-level rise
Exam cue: Use mapped, numerical, graphical, fieldwork or source evidence to explain process and inter-relationship, then make a scale- and context-aware judgement.
Concept 4
3.4.4 Global impacts and impacts on people and environment in two contrasting places
Risk pitfalls and guardrails
Calling the greenhouse effect entirely human-made or treating a single short-term observation as sufficient climate evidence.
Guardrail: Do not import legacy or Eduqas structures, invent an option split or make claims that exceed the named evidence and assessment controls.
Importing the legacy WJEC 3110 structure, an Eduqas option pattern or an England 9-1 grading convention.
Guardrail: Do not import legacy or Eduqas structures, invent an option split or make claims that exceed the named evidence and assessment controls.
Treating an annual Unit 2 theme, local example or Unit 4 Resource Pack as a separate qualification or a compulsory option for every learner.
Guardrail: Use one centre-selected theme valid for the submission year; do not split themes into separate qualifications or replace the live Assessment Pack with guidance examples.
Memory anchors
Milankovitch cycles
Long-term orbital variations affecting the distribution of solar energy.
greenhouse effect
Natural atmospheric warming as gases absorb and re-radiate outgoing energy.
enhanced greenhouse effect
Additional warming caused by increased greenhouse-gas concentrations from human activity.
ice core
Layered ice evidence containing past atmospheric and temperature indicators.
Keeling curve
The long-running record showing atmospheric carbon dioxide concentration.
climate consequence
A physical or human outcome resulting from a changing climate.
Checkpoint rule
Do the check-up only after you can summarize each concept in one sentence and identify one dangerous pitfall from memory.
