Decrease of Anthropogenic Influence on
Atmospheric CO2 Levels

The Experiment

• Trend 1 1 increase in the CO2 level from 2000
  to 2010, then plateau to 2070.
• Trend 2 1 increase in the CO2 level from 2000
  to 2040, then plateau until 2070.
• Trend 3 1 increase in the CO2 level from 2000
  to 2070.
• Control Global Warming Run with a CO2 trend
  analogous to the current trend- 1.9 increase.

Run 1 vs. Control

• CO2 levels in 2010
• Atmospheric CO2 410 ppm
• Very encouraging, but highly unlikely
• Snow and ice coverage increases at the poles and
  on land in the Northern Hemisphere
• Global average temperature decrease -6.97

Run 1 vs. Control
5
Run 2 vs. Control

• CO2 levels in 2040
• Atmospheric CO2 553ppm
• No need to show a temperature map because it is
  analogous to Run 1
• Curbing the trend of melting snow and ice with a
  more realistic CO2 trend
• Evaporation occurs more over land and tends to
  rain out over the oceans

Run 2 vs. Control
8
Run 3 vs. Control

• CO2 levels in 2070
• Atmospheric CO2 level 746ppm
• Generally less dramatic cooling
• Ground albedo decreases at the South Pole
• Most realistic of the three runs based on CO2
  trend

Summary

• Our models show an optimistic future for the
  world if changes are made now
• Current Proposal in the Senate
• Systematic reduction of CO2 emissions by
  cap-and-trade policy
• Encourage people to Go Green
• It WILL HELP!
