Which of the following is NOT a source of data used to understand climate?
Liquefaction zones from earthquakes stored in the geologic record
Can humans just adapt to climate change?
Yes, but it depends on the rate of temperature change as well as intensity.
Which of the following is NOT expected to be caused by global warming?
Increased earthquake activity
What is the difference between a variable and permanent gas?
Abundance of variable gases in the atmosphere change and abundance of permanent gases do not.
Which of the following is FALSE about the ocean conveyor belt?
Movement of water in the ocean conveyor belt is speeding up due to human activities.
Which of the following does NOT contribute to climate change?
Not C, D
What is the cryosphere?
The Earth's ice and snow
How do scientists measure the amount of carbon dioxide in the atmosphere for dates prior to the 1955?
From air bubbles in glacial ice from cores
Which of the following is considered a variable gas?
Which of the following is NOT a way in which hazards are related to climate?
Volcanic eruptions are related to warmer climates.
What two factors are often used for basic classification of global climate zones?
Average monthly temperature and precipitation
Which of the following is NOT an important part of how the atmosphere is warmed through the greenhouse effect?
Radiation from the sun is reflected by the Earth's surface.
Which gas comprises most of the atmosphere?
What is important about amounts of carbon-14 in living samples?
It can indicate sunspot activity.
Which of the following is NOT a reason why sea level rise is a problem for humans?
It will deplete fish populations.
Once glaciers retreat and melt away, they can never come back.
Aerosols are harmful gases emitted from spray canisters.
Volcanoes are capable of causing short-term global climate change.
No one really knows how the concentrations of atmospheric carbon dioxide have changed in the distant past, because we have only been directly measuring it since 1955.
Glaciers have always covered the continents and it is only in our current time that the glaciers have been confined to polar climates.
What is the difference between a glacial and interglacial period?
Glacial periods are colder than interglacial periods.
Which of the following does NOT play an important role in glaciation?
Abundance of oxygen in the atmosphere
Which of the following is NOT a typical hazard involved with glaciers?
Glaciers can trigger volcanic eruptions.
Which of the following is NOT a Paleo-proxy data source?
Which of the following is NOT a piece of evidence that the Earth is warming?
Earthquake activity is increasing.
How have global temperatures changed over the last 800,000 years?
They have increased and decreased many times.
What is the greenhouse effect?
The absorption of infrared radiation by the atmosphere
What are aerosols and why are they important?
Aerosols are very small liquid or solid particles that reflect sunlight.
Which of the following is FALSE about the paleo-proxy record?
It includes people's written recollections from many centuries ago.
The depletion of the ozone layer is caused by the greenhouse effect.
Climate and weather are essentially the same things, just different names.
The warming we see now and have seen in the past can be explained by changes in solar energy.
Most of the increase in global temperatures over the past century or so can be attributed to natural changes in the Earth's tilt, orbit and wobble.
How is the Earth's climate changing?
It is warming probably due to increased levels of CO2 in the atmosphere.
Which of the following is NOT a source of carbon dioxide for our atmosphere?
When the Earth warms, won't the areas that we lose to agriculture (like the U.S. Midwest) just be replaced by new areas that are now too cold for farming (like Northern Canada)?
Maybe. There is more to farming than just climate and more needs to be known about the soil characteristics in those areas.
Which of the following is a statement involving climate rather than weather?
The winters here are dry and warm.
Climate refers to the average weather in a given location over a long period of time.
Global temperatures have fluctuated many times in the last 800,000 years causing glacial and interglacial events.
Which of the following is NOT a way to reduce emissions from greenhouse gases?
Capture greenhouse gas emissions from power plants and release them in the upper atmosphere
Your great-great grandmother may have written on her wedding photos about the weather on the day of her wedding. What type of data would this be?
Which gas accounts for the majority (more than half) of the anthropogenic greenhouse effect?
Which of the following statements about climate change is FALSE?
Climatologists now have complete historical temperature data for the past 100,000 years of the Earth's history.
Which of the following is a reason why sea level will rise as a response to global warming?
Increased temperatures will cause the ocean water to expand.
Currently, the Earth's climate is cooling.
The gases that comprise most of the atmosphere have little impact on the weather.
Global warming is expected to increase the amount of precipitation in some areas and decrease it in others.
Most of the Earth's atmosphere is comprised of oxygen.
Which of the following is NOT a problem associated with ice sheets melting?
Melting glacial ice on the Arctic Ocean will contribute most to rising sea level due to its melting directly into the ocean.
If we cut down the tree in your great-great grandmother's backyard and analyzed the tree rings, what type of data would this be?
What best describes how carbon dioxide concentrations in the atmosphere have changed in the last 500 years?
Concentrations were mostly steady until ~1850 when they began to increase.
Which of the following is FALSE about glaciers?
Today, we live in a glacial interval due to the large continental glaciers in Antarctica and Greenland.
Infrared radiation emitted from the Earth is absorbed and re-emitted by greenhouse gases in the atmosphere.
In addition to reducing emissions of greenhouse gases, scientists are working on plans to store the gases instead of releasing them into the atmosphere.
Because glaciers move so slowly, they do not pose any sort of threat to society.
Which of the following episodes of climate change was believed to be caused by human interaction?
Warming over past 150 years or so
Most scientists think that it is too late to stop global warming and that we should just deal with the effects as they come.
A significant portion of the observed global warming over the past 100 years is from natural forces.
The greenhouse effect is completely natural and necessary for human life to exist on Earth.
Why do scientists think that the current global warming situation is NOT caused by natural forces?
Because of the burning of fossil fuels, the Earth is warmer today than in any other period in the last 800,000 years.
Scientific consensus states that the Earth is warming right now and this effect can be attributed in part to human influences.
