Anthropocene

Paper #2 Topic
Type a 10-page paper (the works-cited list is page 11) in which you explain core concepts of Earth System Science and demonstrate how, in one particular way, your major connects to Earth System Science and can contribute to stabilizing the Earth System. Besides Earth System Science, use five relevant and reliable sources from a PCC Shatford Library database and two optional sources from other places.

MAJOR: Administration of Justice

Paper #2 Outline
Page 1, first half: Intro + thesis
Pages .5-4: Explain core concepts of Earth System Science
Pages 2nd half of page 1 to the end of page 2
Gaia, Lovelock, and thus invented what became Earth System Science (chapter 1)
Earth System
Positive and Negative Feed Back Loops (chapter 2)
what are they, PFBLs & NFBLs
what is a biogeochemical cycle
the ES is a set of biogeochemical cycles, for example oxygen cycle
Page 3
Regulation (chapter 3)
Topic Sentence: Through NFBLs, the regulation of the biogeochemical cycles that make up the Earth System balances and maintains a particular state of the Earth System.
Evidence/example
For example, through the bathtub analogy, the regulation of the oxygen cycle becomes clear.
explain evidence/example
explain bathtub analogy to clarify the concept of regulation–water level kept from getting either too low or too high
explain how, in the oxygen cycle, NFBLs keep the O2 level from getting either too low or too high
sweet spot 17%-25 to 30% for the last 370 million years–this is the balance
too low? an ocean-based NFBL kicks in which the decrease in O2 in the oceans triggers an increase in organic carbon burial, which increases atmospheric O2 levels
too high? a land-based NFBL kicks in by which fire burns vegetation, preventing the burial of that organic carbon
Revolution (chapter 4)
Topic Sentence: A revolution of the Earth System happens when PFBLs disrupt a particular state of the Earth System and its biogeochemical cycles and an example is ___.
Evidence/example
the Great Oxygenation event
Explain evidence/example
aerobic photosynthesis (stage 1 of the O2 rocket)
O2 allowing for O3 allowing for O2 allowing for O3 in a PFBL
Page 4
Anthropocene (chapter 5)
what is it
why is it a revolution in the ES (destabilizing)
geological history intersecting with human history in such a way that humans shift the direction of geological history, that is, end the Holocene and kick off the Anthropocene
Projection (chapter 6)
vs prediction to define projection
trouble ahead or revaltivly smooth sailing depending on what humanity does
Sustainability (chapter 7)
what is it
how is it done
Pages 5-9: Demonstrate how, in one particular way, your major connects to Earth System Science
ESS and the major/topic: page 5
describe and define the particular problem: page 6
solution: how the major can address the problem: pages 7-8
why is it important for the major tackle that problem: page 9
