Chapter 7

Question 1

Global reference scenario

Answer 1

Set of agreed-upon projections of future emissions with socioeconomic narratives - crucial input for climate scenario analysis.

Question 2

Representative Concentration Pathway

Answer 2

Adopted by IPCC, - scenarios modeling the level of radiative forcing, caused by given level of GHG concentration

Question 3

Radiative forcing.

Answer 3

difference in energy (in watts per square meter) between incoming solar radiation and outgoing infrared radiation at the top of the atmosphere.

Question 4

climate scenario?

Answer 4

Narrative to sketch future world state as CC advances

Question 5

Net Zero def

Answer 5

Reducing global emissions to zero in almost every sector of global economy + balancing residual emissions (e.g. from agriculture, aviation) with removals & offsets

Question 6

SSP def

Answer 6

Shared Socio-Economic Pathway - scenarios showing how С is influenced by social and economic factors (population, economic growth, education, etc.)

Question 7

Which two RCP pathways are the most widely used?

Answer 7

RCP 2.6 - for reaching Paris <2C goal
RCP 8.5 - “business as usual”

Question 8

Break down five SSP scenarios, what are they about

Answer 8

SSP1 - high focus on sus
SSP2 - Business as usual
SSP3 - regional rivalry btw countries
SSP4 - high degree of inequality
SSP5 - fossil-fuel development

Question 9

def Integrated Assessment Model

Answer 9

Model that can assess combo of social, economic, energy, emissions, climate factors

Question 10

What are the components of scenario analysis

Answer 10

1. Choice of scenario + parameter setting (macroeconomic, like GDP growth, energy demand, policies)
2. Analytical choices:
   Choose scope (e.g. supply chains) and qualitative + quantitative methods
   Choose timescale, data availability, types of climate hazards
3. Get output (revenues, asset valuations, asset stranding).
