Climate Change Practice Questions
Terms in this set (56)
Decreasing acid rain can result in an increase in global warming.
The reflectivity of different surfaces on the planet is called...
Which of the following has the highest albedo?
It is predicted that California will experience an increased frequency of wildfires.
GRAPH: What does the following graph of the ratio of Carbon-13/Carbon-14 indicate with respect to global warming?
the carbon is coming from burning of fossil fuels showing the contribution of human activities
IMAGE: What does the following image signify?
coral bleaching caused by warming and declining pH in the ocean caused by CO2 emissions
Approximately how much has the planet warmed already compared to pre-industrial levels?
Which of the following does not release CO2 during the production of energy (excluding extraction of any raw materials, building of infrastructure, and disposal)?
Which of the following would not lead to a positive feedback loop causing more climate warming?
The evaporation of water where water condenses into clouds that reflect solar radiation back into space.
To avoid dangerous climate change, climate scientists claim this is the most we can allow temperature to increase compared to pre-industrial average temperature:
This is a purely man-made greenhouse gas while in the troposphere andcontributes to ozone depletion in the stratosphere.
This gas is released by anaerobicdecomposition in landfills and the guts of cattle and has a global warming potential of 23-25 over a 100 year time period.
This gas is released by the burning of somefossil fuels, is not a greenhouse gas, but does contribute to acid rain.
SO2 sulfur dioxide
This is the most abundant greenhouse gas in the atmosphere.
H2O water vapor
This greenhouse gas is released when you burn a fossil fuel or a biofueland is converted to glucose by plants.CO2 carbon dioxide
CO2 carbon dioxide
This gas is released by plants and is split byhigh energy UV radiation in the stratosphere.
This gas traps heat in the troposphere and is an irritant to lungs and eyes as a component of smog
This gas can be released by soils and is almost 300 times more potent at trapping heat than CO2
N2O nitrous oxide
Based on the predictions of how global warming will affect California which one of the following is not likely going to happen?
Decrease in the urban heat island affect that will decrease yields on urban farms
The greenhouse effect is human caused.
Natural systems (respiring animals, decomposition, fires, the ocean) contribute approximately 700 giga-tons of Carbon (GtC) to the atmosphere each year. About how much Carbon do human activities contribute to the atmosphere each year?
The different greenhouse gasses all have the same ability to trap heat per molecule, it is the amount that is released that makes the only difference in their overall effect.
0 / 1 pts
Which of the following absorbs the most heat associated with global warming?
Currently we are experiencing the hottest climate in the history of the planet.
How many of the hottest 15 years recorded between 1880-2015 occurred before 2000?
Human activities release far more CO2 than natural systems.
Which of the following was not a contributor to past ice ages?
The IPCC states that it is unlikely that human activities have caused climate change.
This is absorbed and re-radiated by greenhouse gasses
long wavelength infra-red
GRAPH: What is important about the following graph with regard to future global warming?
we have enough fosil fuels to release enough CO2 to go well past 2 C warming
Which of the following is not likely to result from a warming climate?
Increased summer sea ice at the northern pole
Which of the following is NOT likely to result from an increased amount of CO2 in the atmosphere?
Decreased amount of stratospheric ozone.
What is the best definition of phenology?
The study of the timing of biological events
Which of the following is an example of a phenological change that we might expect with global warming?
A bird species is now laying its eggs 10 days earlier than normal.
What is the current level of CO2 in the atmosphere?
The ratio of oxygen isotopes (18O and 16O) that can give us an estimate of temperature is called a(n)...
This is used by plants in photosynthesis.
This is not blocked by stratospheric ozone and can cause sunburns and increases risk of skin cancer
More of this is now making it to the earth's surface due to stratospheric ozone depletion.
This breaks apart oxygen in the stratosphere allowing the creation of ozone.
This is an electron
This is 2 protons and 2 neutrons
This is heat coming from the sun
short wavelength infra-red (IR)
This is trapped by greenhouse gasses contributing to global warming.
long wavelength infra-red (IR)
What is the best description of range migration or range shift associated with global warming?
When a species moves toward the pole in response to a warming climate.
Which of the following Representative Concentration Pathways would result in the largest temperature increase over time?
What is the current estimated upper limit for sea level rise through 2100?
Which of the following would NOT contribute to sea level rise?
Melting of the sea ice on the northern pole
Sierra snowpack is predicted to increase in the southern part of the range, but to decrease in the northern part of the range.
What is the current social cost of carbon estimated by the U.S, government?
If Stanford is correct with their estimate of the social cost of carbon, then just using emissions from 1990-2015, the U.S. would be in debt how much compared to our current national debt?
Stanford recently questioned the U.S. government estimate of the social cost of carbon. The Stanford group suggests it should be...
Melting of ice and warming of polar oceans could slow and possibly stop the thermo-haline circulation.
Which of the following is TRUE of greenhouse gasses?
Once released into the atmosphere CO2 can remain for many years.
The reason why it is warming faster in the arctic than in the temperate or tropical regions is (choose the best answer):
The loss of snow and ice due to warming decreases the reflectivity of the arctic.
Although water vapor is a greenhouse gas we do not account for it the same we we do with the gasses that are released by human activities.
