GlobalWarmingQ4-v1s1

[edit | edit source]

1. Computer modeling has conclusively established that anthropogenic warming has occurred since 1910.

___ a) true
___ b) false


2. The cryosphere refers to

___ a) the north and south poles
___ b) the upper atmosphere

___ d) two of these are true


3. Computer models accurately model feedback mechanisms associated with how the soil will retain or release CO2 as the earth warms.}

___ a) true
___ b) false


4. Stefan-Boltzmann radiation is called a negative feedback mechanism because if the sun's radiation increases, the Stefan-Boltzmann law ensures that more heat is lost from the planet to compensate.

___ b) false


5. Computer models accurately model feedback mechanisms associated with the role of clouds as a feedback mechanism.}

___ a) true
___ b) false


6. The Stefan-Boltzmann law plays a central role in establishing a planets temperature as the sun heats the planet with thermal (infra-red) radiation adding to the other solar radiation onto the planet

___ a) true
___ b) false


7. The Stefan-Boltzmann law plays a central role in establishing a planets temperature as the sun heats the planet until the thermal (infra-red) radiation away the planet rises to match the solar radiation onto the planet

___ a) true
___ b) false


8. While computer modeling indicate that the warming since 1970 is dominated by man-made greenhouse gas emissions, they are unable to conclusively ascertain whether the warming from 1910 to 1945 was anthropogenic.

___ a) true
___ b) false


9. How is the validity of a computer model typically tested?

___ a) by verifying its ability to calculate current climate conditions.
___ b) all of these are true
___ c) by verifying its ability to calculate past climate conditions.
___ d) by making predictions about future years and seeing if they come true.


10. Analysis of the uncertainties associated with feedback suggests that the "worst-case" scenario is more difficult to model.

___ a) true
___ b) false


11. Stefan-Boltzmann radiation is called a negative feedback mechanism because if the sun's radiation increases, the Stefan-Boltzmann law ensures that this heat is retained by the planet.

___ a) true
___ b) false


12. Analysis of the uncertainties associated with feedback suggests that the "worst-case" scenario is easier to model.

___ a) true
___ b) false


13. Changes in ice-albedo refers to changes in

___ a) how much ice is melted during the summer months
