Sort it!, Fact, Opinion, or Prediction?

Write each statement number into the correct category box. A fact is a measurable, verifiable claim. An opinion is a personal judgement or value statement. A prediction is a forecast about what might happen in the future.

1. Australia emits approximately 15 t CO₂ per person per year. 2. Australia should ban all coal exports immediately. 3. Global temperatures will rise by at least 2°C by 2100 if emissions continue at current rates. 4. Fossil fuels still supply about 80% of world primary energy. 5. Developing nations do not have a moral right to industrialise using fossil fuels. 6. China is the world's largest total CO₂ emitter. 7. Renewable energy will become the dominant source of electricity globally by 2040. 8. The Paris Agreement aims to limit warming to 1.5°C above pre-industrial levels.
