The Greenhouse Effect

Test yourself on The Greenhouse Effect

• What could happen if atmospheric concentrations of greenhouse gases keep rising?

• What can be concluded from the fact that most climate scientists agree the greenhouse effect is causing global warming?

• What would happen to the Earth's temperature if the atmosphere contained no greenhouse gases?

• Why could rising atmospheric concentrations of greenhouse gases cause global temperatures to rise too high?

• Why do greenhouse gases acting as a natural insulating layer keep the Earth warm?
