Module 3 Quiz

A “Tragedy of the Commons” requires both a “tragedy” and a “commons.” What does the tragedy consist of in a system that is governed by the “Tragedy of the Commons” model?

A “Tragedy of the Commons” is most associated with:

Fisheries are observed to experience the “Tragedy of the Commons” when they:

Fisheries are often described as being afflicted by “the Tragedy of the Commons.” Which of the following statements is true from this description of the situation?

To conserve the Alaska pollock fishery, the US government brought in permitting requirements, limited the number of allowed fishermen, imposed quotas, and even closed areas to fishing. Why did the government do this?

Why can common use of a resource result in destruction of that resource?

Many places had common resources that’s uses were shared but did not deplete these resources. This is because the local people employed the following approach to avoid commons degradation:

Why is the “commons” part of the “Tragedy of the Commons” term potentially a poor name?

A property rights approach is having trouble dealing with some important “Tragedy of the Commons” issues. One of these is atmospheric pollution and climate change. Why might a property rights approach, in particular, be failing to curb the problem?

So far, the global average temperature of the 21st century has been higher than that of the 19th century. True or false?

Can you use weather data to determine the climate? Why?

If the Earth is in “energy balance,” this means:

Near the end of the Cretaceous period, about 65 million years ago, the Earth was much warmer than it is today. Scientists ascribe this, in part, to:

Over the past 800,000 years, when was carbon dioxide in the atmosphere the highest?

Which of the following data sources informs us that the Earth’s climate was once in a glacial period?

According to proxy and instrumental data, what is the general trend of global temperature in the last 200 years?

If there was no atmosphere, the Earth’s average temperature would be about -18 degrees Celsius (which is below 0 degrees Fahrenheit). The Earth is much warmer than this! Why?

Why is carbon dioxide (CO₂) thought to act as a “greenhouse gas”?

How might a change in albedo, caused by increased forest cover, warm the Earth?

What physical feature of the “stable isotopes” in water means that they vary with climate in ice cores, so they can tell us about changes in Earth’s temperature over time?

How might both ice sheets and vegetation change the climate?

In what situation is instrumental data preferable to proxy data?

Why are sea levels projected to further increase over the next century?

If Earth had no atmosphere, its average temperature would:

Venus is closer to the Sun than the Earth and its Moon. If Venus and the Moon had the same atmosphere (be it thick or thin) and roughly the same albedo, we could confidently predict that:

Earth’s climate has recently been linked to the Milankovitch cycle. If this natural trend were to continue, we would expect that the average temperature of the Earth will do what over the next 10,000 years?
