1. CLIMATE CHANGE - 5
The most important anthropogenic greenhouse
What is - CO2 (carbon dioxide)
Natural cycles of climate change caused primarily by Earth’s varying tilt and distance from the Sun
What is – Milankovitch Cycles (orbital forcing)
A cycle in which an effect amplifies its cause, leading to a runaway excursion from equilibrium
What is - Positive feedback.
The role of the Sun in climate change at present
What is – Low to negative radiative forcing (Sun’s output is steady and slightly cool)
The relative decrease of this isotope is a smoking gun for anthropogenic carbon in the atmosphere
What is - Carbon 14 (this short-lived radioactive isotope is absent from fossil fuels)
2. SOCIETY & Science
This event fomented world-wide simultaneous empathy because of the telegraph
What is – the sinking of the Titanic
Industralization started when people were able to harness this kind of energy in these regions
What is – water power, in the countryside
This country is no sunnier than Olympia, yet it leads the world in solar power production.
What is - Germany.
When two conflicting hypotheses explain past data with equally well, science dictates we accept the
one with more of this property.
What is - Predictive power
Notion that it is wiser to prepare for unproven danger than to assume that a system is safe.
What is - The Precautionary Principle
3. HUMANS and IMPACTS
This process gave the status quo a high degree of immunity to change.
What is - Evolution
New name for the Holocene which reflects human impacts on Earth
What is - The Anthropocene?
Number of major extinction events in Earth history, before the presently occurring event.
What is – Five
This IPAT factor produces the greatest growth in carbon emissions
What is - A for Affluence (GDP per capita)
Human behavioral programming is highly diverse, and changes rapidly over time because of this
mode of inheritance
What is - Culture (or nurture)
4. PEOPLE - 5
This fictional character woke up to an unfamiliar world
Who is – Rip Van Winkle
She wrote the Declaration of Sentiments, presented at Seneca Falls in 1848
Who is – Charlotte Perkins Gilman
Swede who happily predicted a century ago that coal burning would warm the Earth
Who is – Svante Arrhenius (1896)
Young geophysicist whose careful measurements of atmospheric CO2 revealed rapid global
warming
Who is – Dave Keeling (starting in 1958)
This is a feature of the channeled scablands that J. Harlen Bretz argued could not be explained by
gradual erosion.
What are - hanging valleys, glacial eratics, giant pot holes, dry falls, giant ripples?
FINAL JEOPARDY QUESTION The idea of human rights became popular when this organization won this prize in this year
What is – Amnesty International, Nobel Prize in 1977
5. HISTORY of IDEAS - 5
Descartes used this foundation to “prove” the existence of God
What is – I think, therefore I am.
Understanding of these fundamental categories of human experience changed between 1880-1920
What are – time and space
Louis Menand criticized abolitionists for these perspectives
What are idealism and anti-politics
Action to change the world is slow to change the world is slow to catch up with this
What is – knowledge / ideas / understanding
In this year, the United Nations was founded.
When is – 1945
WINTER or Double jeopardy
Approximate timescale for the earth to reach new thermal equilibrium after greenhouse gas
emissions cease
1000 years
Earth Dynamics Jeopardy (eda7889)
NEXT quarter
Conservative physicist who became radicalized by his early realization of anthropogenic global
warming
Who is – James Hansen (1988)
State of the Earth when incoming heat is balanced by heat radiated away
What is (Thermal) Equilibrium
Disagreements about climate change are driven by these
What are – values
ROUND 2 - Likelihood that present observed global warming is caused by humans, according to
the IPCC
What is – (99%)
Abbreviated IPCC, panels of scientists review studies and produce assessments for approval by this
group
What is - The Intergovernmental Panel on Climate Change.
English steam engineer who accurately quantified climate sensitivity nearly a century ago, and was
not believed in his lifetime.
Who is – G.S. Callendar, 1938
Net cost of retrofitting buildings with recommended energy saving features
What is – Zero or less (green buildings can save money)
Impact = PAT stands for this
What is - Population * Affluence * Technology
Cause of the features observed at Dry Falls, and timing of their occurrence
What is – periodic flooding from Glacial Lake Missoula, about 11,000 years ago
Trend in the growth rate of human population, globally
What is - Decreasing growth rate
A Hypothesis may become this when it has made a prediction and withstood a substantial test.
What is - A Theory
Process in which the Earths' reflected insolation decreases with increased ice melt, and vice versa.
What is - Ice albedo feedback
Building up an existing technology or strategy, to remove 25 billion tons of carbon emissions
annually, within 50 years.
