Compare current CO2 levels to the highest concentrations from the past 450,000 years. Based on the information found on these websites and in the textbook, answer the following questions:

  • What is the current CO2 concentration in parts per million (ppm)?
  • Is this higher or lower than the highs over the past 450,000 years?
  • From which three sources do humans add CO2 to the atmosphere?
  • Which two sources take CO2 out of the atmosphere?
  • How does deforestation contribute to the global warming process?
