Decrease of Anthropogenic Influence on Atmospheric CO2 Levels

This study by Tanya Bruskewitz, Amy Schmidt, and Matt Serwe examines the future of atmospheric CO2 levels under various trends, highlighting potential decreases in anthropogenic influence. The findings suggest that adopting cap-and-trade policies and promoting green initiatives could lead to substantial reductions in CO2 emissions. The analysis demonstrates a projected increase in CO2 levels to 746 ppm by 2070 but indicates significant global temperature rebounds and enhanced snow and ice coverage if proactive measures are implemented. This research calls for immediate action to secure a healthier planet.

  1. Tanya Bruskewitz, Amy Schmidt, Matt Serwe Decrease of Anthropogenic Influence on Atmospheric CO2 Levels

  2. 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.

  3. 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°

  4. 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

  6. Run #2 vs. Control

  7. 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

  9. Run #3 vs. Control

  10. 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!
