I just made a video that is available in three places:

Lake Campus Symposium: Creating a bank so students won't break the bank
https://bitbucket.org/Guy_vandegrift/qbwiki/wiki/Home/
The conversion to LaTeX should make this bank more compatible with VLEs
Quizbank - Quizbank/Python/LaTex - Category:QB/LaTeXpdf - QB - edit news
Students with minimal Python skills can now write numerical questions

See special:permalink/1863382 for a wikitext version of this quiz.

\question Changes in ice-albedo refers to changes in\ifkey\endnote{ placed in Public Domain by Guy Vandegrift: {\url{https://en.wikiversity.org/wiki/special:permalink/1863382}}}\fi
\begin{choices}
\choice how much CO2 is absorbed by the sun
\CorrectChoice how much the Earth's surface absorbs or reflects incoming sunlight
\choice how much ice is melted during the summer months
\end{choices}

\question The cryosphere refers to\ifkey\endnote{ placed in Public Domain by Guy Vandegrift: {\url{https://en.wikiversity.org/wiki/special:permalink/1863382}}}\fi
\begin{choices}
\choice the north and south poles
\choice the upper atmosphere
\choice the highest mountains
\CorrectChoice two of these are true
\end{choices}

\question 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.\ifkey\endnote{ placed in Public Domain by Guy Vandegrift: {\url{https://en.wikiversity.org/wiki/special:permalink/1863382}}}\fi
\begin{choices}
\CorrectChoice true
\choice false
\end{choices}

\question Computer modeling has conclusively  established that anthropogenic warming has occurred since 1910.\ifkey\endnote{ placed in Public Domain by Guy Vandegrift: {\url{https://en.wikiversity.org/wiki/special:permalink/1863382}}}\fi
\begin{choices}
\choice true
\CorrectChoice false
\end{choices}

\question How is the validity of a computer model typically tested?\ifkey\endnote{ placed in Public Domain by Guy Vandegrift: {\url{https://en.wikiversity.org/wiki/special:permalink/1863382}}}\fi
\begin{choices}
\choice by verifying its ability to calculate past climate conditions.
\CorrectChoice all of these are true
\choice by verifying its ability to calculate current climate conditions.
\choice by making predictions about future years and seeing if they come true.
\end{choices}

\question 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\ifkey\endnote{ placed in Public Domain by Guy Vandegrift: {\url{https://en.wikiversity.org/wiki/special:permalink/1863382}}}\fi
\begin{choices}
\CorrectChoice true
\choice false
\end{choices}

\question 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\ifkey\endnote{ placed in Public Domain by Guy Vandegrift: {\url{https://en.wikiversity.org/wiki/special:permalink/1863382}}}\fi
\begin{choices}
\choice true
\CorrectChoice false
\end{choices}

\question 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.\ifkey\endnote{ placed in Public Domain by Guy Vandegrift: {\url{https://en.wikiversity.org/wiki/special:permalink/1863382}}}\fi
\begin{choices}
\CorrectChoice true
\choice false
\end{choices}

\question 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.\ifkey\endnote{ placed in Public Domain by Guy Vandegrift: {\url{https://en.wikiversity.org/wiki/special:permalink/1863382}}}\fi
\begin{choices}
\choice true
\CorrectChoice false
\end{choices}

\question Computer models accurately model feedback mechanisms associated with the role of clouds as a feedback mechanism.\ifkey\endnote{ placed in Public Domain by Guy Vandegrift: {\url{https://en.wikiversity.org/wiki/special:permalink/1863382}}}\fi
\begin{choices}
\choice true
\CorrectChoice false
\end{choices}

\question Computer models accurately model feedback mechanisms associated with how the soil will retain or release CO2 as the earth warms.\ifkey\endnote{ placed in Public Domain by Guy Vandegrift: {\url{https://en.wikiversity.org/wiki/special:permalink/1863382}}}\fi
\begin{choices}
\choice true
\CorrectChoice false
\end{choices}

\question Analysis of the uncertainties associated with feedback suggests that the "worst-case" scenario is easier to model.\ifkey\endnote{ placed in Public Domain by Guy Vandegrift: {\url{https://en.wikiversity.org/wiki/special:permalink/1863382}}}\fi
