Global Climate Change
Which will reduce the total amounts of greenhouse gases?
Produce electricity from wind rather than burning coal.
What is the leading source of increasing amounts of methane in the atmosphere contributing to global climate change?
The beef industry
Which of the following statements about current climate change is FALSE?
All regions on Earth are predicted to be affected by climate change in the same way.
Which human activity most directly affects the release of the greenhouse gas carbon dioxide into the atmosphere?
Burning coal for electricity
Which human activity is a primary source of increasing amounts of the atmospheric greenhouse gas, carbon dioxide?
Burning fossil fuels
What effect will changing over to hybrid and electric vehicles have on climate change?
Carbon dioxide emissions will decrease because less fuel will be burned.
Which human activity is a major reason for the increasing amounts of the atmospheric greenhouse gas, carbon dioxide?
Deforestation
What is an example of an engineering solution that could help reduce the impact of climate change?
Designing new vehicles that do not release greenhouse gases in order to limit how much climate change occurs.
Which of these changes in human activities would reduce carbon dioxide emissions into the atmosphere?
Encouraging more people to carpool or use public transportation
Which is a main way that increasing amounts of greenhouse gases raise global temperatures?
Greenhouse gases absorb and release heat back towards Earth
How does increases in greenhouse gases like carbon dioxide (CO2) relate to global warming?
Greenhouse gases trap heat from the Sun, causing the atmosphere to get warmer.
Recent research on global climate change indicated the top way(s) that humans can reduce their contribution to climate change. Which of the following would have the biggest impact when it comes to reducing human activity that contributes to climate change?
Having fewer children and eating a vegetarian diet
The amount of carbon dioxide in the air has been going up for the last 200 years. This is mostly because of
Humans burning fossil fuels (like when we drive cars)
Which of the following human activities is a primary source for increasing amounts of the atmospheric greenhouse gas, methane?
Raising cattle for beef and other forms of agriculture
Which of these changes in human activities would reduce nitrous oxide emissions into the atmosphere?
Reducing the amount of nitrogen-based fertilizers applied to farm fields
Which of these ways of making electricity creates the most carbon dioxide?
burning coal
Which of these activities puts the least amount of carbon dioxide into the atmosphere?
riding a bicycle
Which human activity most directly affects the release of the greenhouse gas methane into the atmosphere?
Cattle ranching
Increased level of greenhouse gases in the atmosphere have been responsible for which result over the last 50 years?
Changes to climate patterns
What greenhouse gas was identified as a factor behind ozone depletion, leading many countries to phase out its use in the 1980s?
Chlorofluorocarbons (CFCs)
Which of the following is the best description for how atmospheric gases relate to global warming and climate change?
Increased atmospheric gases trap heat from the sun, causing global warming and climate change.
Which of the following is the biggest reason why atmospheric greenhouse gas levels have increased in the last 150 years?
Increased release of carbon dioxide by humans from burning fossil fuels.
Which is true of greenhouse gases?
Increasing amounts of greenhouse gases have led to both climate change and global warming.
Over the last 25 years, which has been the major effect of increasing amounts of greenhouse gases on average global temperatures?
Increasing temperatures
Which of these technologies, if used in new building construction, would reduce emissions related to climate change? Select all that apply.
Motion-sensor lights that automatically turn off when the room is empty Solar water heating Better insulation
Which of these changes in human activities would reduce methane emissions into the atmosphere by human activities?
Reducing the amount of beef people eat which would lead to less cattle raised for food
Which of these actions will cause the most amount of carbon dioxide to be released into the atmosphere?
Setting your air conditioning to the coldest setting possible
Which describes the changes in the levels of the atmospheric greenhouse gas, carbon dioxide, over the last 70 years?
Strong increase from historical times
Which describes the changes in the levels of the atmospheric greenhouse gas, methane, over the last 50 years?
Strong increase from historical times
How would growing your own vegetables in a garden or buying from a local farmer help to reduce the effects of climate change?
The food travels from a shorter distance, using fewer fossil fuels.
The Earth's average temperature has increased over the last 150 years. Which of the following is the BEST explanation of the cause for this change?
There is more carbon dioxide in the atmosphere
Which describes the effect of increased levels of greenhouse gases on earth surface temperatures?
They keep heat from radiating back into space.
Which is a main process by which dangerous levels of greenhouse gases accelerate climate change?
They trap heat in the lower atmosphere.
Which human activity would help reduce the amount of carbon dioxide in the atmosphere?
Using car pools
Which of these actions will create less carbon dioxide?
Using less electricity (like turning off lights)
