Question
Even without including all the detail of the physical world, models are useful because they help us understand how a system works by looking at a simplified representation of it, thus "some models are useful."
True
False
What is a Representative Concentration Pathway (RCP) as used in the IPCC 5th Assessment?
RCPs describe the amount of a continuously increasing population
RCPs describe the amount of self-reliance of a country
RCPs describe the preservation of local identities
RCPs represent values for the total radiative forcing since 1970 to 2100
Which of the following are the 4 RCPs that are used in the 5th Assessment Summary for Policymakers?
2.6
3
4.5
5.5
6.0
8.5
8.7
a.RCPs describe the amount of a continuously increasing population
b.RCPs describe the amount of self-reliance of a country
c.RCPs describe the preservation of local identities
d.RCPs represent values for the total radiative forcing since 1970 to 2100
Explanation / Answer
True
Some models may be wrong, but some models are useful
______________________________________________________________________________________
d.RCPs represent values for the total radiative forcing since 1970 to 2100
Note: RCPs represent values for the total radiative forcing since 1970 ( pre-industrial values) to 2100
