Answer: Proxy climate data
Computer simulations using equations to predict future climate based on different emission scenarios?
Answer: Global climate models
Testing a climate model by running it from past starting conditions to see whether it reproduces the climate that was actually observed?
Answer: Hindcasting
Deliberate global-scale interventions, such as reflecting sunlight with stratospheric aerosols, that reduce warming by treating the symptom rather than the cause?
Answer: Geoengineering

Answer: IPCC
Area of severe stratospheric ozone depletion over polar regions each spring?
Answer: Ozone hole

Answer: Hydrofluorocarbons (HFCs)
Play it as a class game
Play this set opens it in splycr, where you can host it for your class straight away. Hosting needs no account: put the room code on the projector, and students join from a phone with the code and their first name. Each question plays as multiple choice, and the three wrong options are other answers from the same set.
