Q

RCP 2.6 is ?

A

the most environmentally friendly
- meant to keep global temp rise below 2 degrees by 2100
- strict and very big cuts to all types of emissions

Q

RCP 4.5 is ?

A

the middle scenario
- rise in temp by 2-3 degrees by 2100 and mean sea level rise 35% higher than RCP 2.6
- CO2 peak in 2040, then declines to half of 2050 levels by 2100
- many plants and animals unable to adapt

Q

RCP 8.5 is the?

A

worst case scenario
- co2 emissions continue to rise
- 3+ degree warming
- unlikely but we don’t understand feedbacks and stuff well enough yet

16
Q

can GCMs be applied to small areas

A

yes, through downscaling the global ones

17
Q

why are there so many different models

A
  • they’ve been constantly improved and adjusted
  • fisrt models were crude and simple, now they can model glaciers, dams, human management etc
18
Q

how do you choose the right model

A

there is no right model, so use as many as possible and get a large range of results and possibilities for the future

19
Q

in what cases will you have to plan for a range of worst to best case scenarios

A

in regions with high ranging results

20
Q

what do models do for stakeholders

A

turn raw data they dont care about or understand, into understandable and applicable predictions and scenarios
