Answer the Questions
- Regarding the “3. Carbon Dioxide’s Oversized Footprint” graph from the AGU’s selection offive graphs from the recent IPCC assessment (AR6):
- When it comes to climate change, attention is ‘hyperfocused’ on CO2. Using the identified graph, justify or refute the attention given to CO2.
- In Question 1 of Lab 1, Part 3, you identified emissions scenarios for each of your three Part 1 scenarios for [CO2] in 2100. For each of these emissions scenarios, provide a quantitative estimate for the relative impact of CO2 versus Non-CO2 GHGs.
- Based on the results obtained by comparing the impact of CO2 versus Non-CO2 GHGs, is the attention given to CO2 justified?
- State the primary scientific objective of the Kyoto Protocol. (Be certain to state your source(s)).
- Summarize the primary scientific objective of the Paris Agreement. (Be certain to state your source(s)).
- State a primary outcome achieved at COP26 (2021 United Nations Climate Change Conference). (Be certain to state your source(s)).
- Using your own words, distinguish between “net-zero” and “Carbon neutral”. (Be certain to provide your source(s) – e.g.,What’s the Difference Between Carbon Neutral and Net-Zero?). What makes net-zero objectives ‘more aggressive’ than others?
- For the worst-case emissions scenario you identified in Question 1 of Lab 1, Part 3:
- To achieve the net-zero objective by 2050, by how much must annual CO2 emissions be reduced in GtCO2/yr?
- To what extent must reduction through Carbon extraction apply? (Note: Refer to Section 5, “Carbon Extraction”, from the AGU’s selection offive graphs from the recent IPCC assessment (AR6) for additional context.)
- Identify a process for sequestering Carbon. To what extent, if any, has this process been commercialized? (Be certain to state your source(s)).
