Why is CO2 accumulating in the atmosphere and what can be done about it ?
The graph below shows carbon dioxide concentrations in the atmosphere in parts per million (ppm) from 1958 until the present. • Questions to consider: • Explain the annual periodicity of the above curve? • What inferences can you make about CO2 concentrations for the next 50 years ?
1. Review Processes ATMOSPHERIC CO2 Direct Air to Sea Exchange (dissolution) Process Process Process Plants and Animals Human use Oceans Process Stored CO2 – Fossil Fuels
Accumulation • Basic principle: Accumulation happens when inputs are greater thanoutputs • For carbon cycle: -Inputs to atmosphere = sources -Outputs from atmosphere = sinks (land and ocean)

The atmosphere 90 92 Human Fuels Oceans Natural Gas Oil Coal One possible solution 4 122 120 Plants, animals and soil Reduce deforestation Reduce emissions from energy use Maintain regrowth of forests
Movement of Carbon in every year during the years 2020 - 2030 Figure 3. This shows the movement of carbon in every year for the years 2020 – 2030. The numbers stand for billions of tons of carbon. Figure 4. This shows the concentration of carbon dioxide in the atmosphere in parts per million (ppm) if levels are stabilized by 2020. Concentration stabilization scenario 122 4
Challenge #1 - How to make this fun, relevant, and not depressing

Understanding how the earth works and how humans fit in is cool Sustainability will provide new opportunities You are not a bad person if you drive a car; you are just a contemporary human. What will a future human drive? materials Individual behavior matters. Collective behavior matters more. There will still be electric guitars in the future. We will figure this out. Enjoy the ride. Be part of it.
Challenge #2 Finding Solutions How can we stabilize carbon emissions over the next 50 years to maintain Carbon emissions instead of continuing on our current path? http://cmi.princeton.edu/wedges/slides.php
