- Volume Approximation. Techniques vary widely in complexity and
can be tailored to use algebra, multivariable calculus,
probability, modeling or numerical analysis. In each case below,
the surface area is determined and multiplied by the depth. The
depth is determined for the Miocene Series to the present.
Link to approaches to finding the
- The deposition rate is estimated using the thickness
accumulated over 25 million years. This rate does not reflect
modern carbon deposition rates.
- Again, techniques vary in complexity. We could assume that
emissions remain stable, at current rates. It appears that
emissions in industrialized nations are leveling off, but
emissions in developing countries are increasing rapidly. Long
term projections of emissions depend on political policy,
technology, population, fossil fuel reservoirs, etc. This provides
an excellent source of discussion in the classroom. Note that this
graph shows carbon dioxide emissions are we are focusing only on
carbon emissions. The computational approach also provides some
challenge since we are looking for the time at which a set value
of total carbon emissions occurs.
