    • He found that the average surface temperature of the earth is about 15°c because of the infrared absorption capacity of water vapor and carbon dioxide.
    • He suggesed a doubling of the carbon dioxide concentration would lead to a 5°c temperature rise.
  • 4. Definition and mechanism of Greenhouse efffect
