Q

Future climate patterns are difficult to predict because it depends on many assumptions and uncertain factors such as:

A
  • population growth
  • the use of carbon fuel as an energy source
  • technological development
  • economic development
  • policies and attitudes towards environment

Q

In some cases, long-term averages may suffice (e.g., for mapping vegetation distribution) but in some impact studies daily time series are essential (e.g., for simulating land slide mechanism in relation to rainfall).

Q

There are two main approaches in emission scenarios as prescribed by IPCC:

A
  • Special Report on Emission Scenarios (SRES) of 2000
  • Representative Concentration Pathway (RCP), 2014
17
Q

This storyline describes a future world of rapid economic growth, with a global population that peaks in the mid 2000’s and declines afterwards.

A

A1

18
Q

The A1 storyline is also split into 3 further groups:

A
  • A1FI
  • A1B
  • A1T
19
Q

_____________ follows a “business as usual” fossil fuel intensive future

A

A1FI

20
Q

is a balanced energy picture

A

A1B

21
Q

is a non-fossil fuel future.

A

A1T

22
Q
  • The __________ storyline follows a more conservative economic world, where economic growth is more limited to smaller regions of the world.
A

A2

23
Q

In A2, Technological change is slower in this _______, while high fertility rates result in a booming population.

A

storyline

24
Q

In A2, Technological change is slower in this storyline, while high _______ result in a booming population.

A

fertility rates

25
Q

The B1 storyline assumes the same population growth as the A1 storyline. It differs in that it has less of a material intense society, and __________.

A

focuses more on clean and efficient technologies

26
Q
  • It focuses on local and regional solutions to environmental protection and social equity.
  • Local solution to sustainability
  • continuously increasing population at a lower rate than in A2; - less rapid technological change in B1 and A1
A

B2

27
Q

t takes emphasis on global solutions to economic, social and environmental sustainability, but with no additional climate incentives.

A

B1

28
Q

We begin with identifying some specific outcomes that you are concerned about, then figure out what kind of social changes could produce those outcomes.

A

Top-down approach

29
Q

Rather than defining the stories first, the________________ defines the GHG trajectories first, then define what human responses corresponds to those trajectories.

A

Representative Concentration Pathways

30
Q

__________________ is the difference between incoming solar radiation and outgoing terrestrial radiation. This power, and thus the difference, is measured in watts per meter squared.

A

Radiative forcing

31
Q

Power coming into Earth - Power leaving the Earth = _____________________

A

Radiative Forcing Amount

32
Q

Changes that have a warming effect are called __________________, while changes that have a cooling effect are called “negative” forcing.

A

“positive” forcing

33
Q

Changes that have a warming effect are called “positive” forcing, while changes that have a cooling effect are called ____________.

A

“negative” forcing

34
Q
  • provides a broad range of scenarios incorporating various socioeconomic and technological factors
  • developed by IPCC, can give the range of plausible future climate
A

Special Report on Emission Scenarios (SRES)

35
Q

primarily focus on greenhouse gas concentrations and radiative forcing

A

Representative Concentration Pathway (RCP)

36
Q

There are four trajectories starting from historical data. The factors for changes in RFA include:

A
  1. predictive solar output
  2. all GHGs that affect energy flows
  3. the use of aerosol and black carbon
  4. snow
  5. land use change
