This memory aid covers Memory Aid within Climate Change for GCSE Chemistry. Revise Climate Change in Atmosphere for GCSE Chemistry with 20 exam-style questions and 15 flashcards. This topic appears regularly enough that it should still be part of a steady revision cycle. It is section 14 of 17 in this topic. Use it for quick recall, then test yourself straight afterwards so the memory aid becomes usable in an answer.
🧠 Memory Aid
SIRF: Sea levels rise, Ice caps melt, Rainfall changes, Flooding increases
For evidence: "TIMC — Temperature records, Ice cores, Melting ice, Changing seasons"
Key numbers to remember:
- 1.1°C = current global warming above pre-industrial
- 280 → 420+ ppm = CO₂ change since 1750
- 23 cm = sea level rise since 1880
- 13% = Arctic ice loss per decade
Quick Check: Give TWO pieces of evidence that global climate change is occurring.
Any two from: rising global average temperatures (measured since 1880); ice core data showing highest CO₂ levels in 800,000 years; retreat of mountain glaciers and Arctic sea ice; sea level rise of 23 cm since 1880; earlier spring events (bird migration, flowering times).
