Analyze and Interpret Data on Atmospheric Chemistry and the Greenhouse Effect

What impact does deforestation have on the amount of carbon dioxide in the atmosphere?

• Deforestation increases the amount of carbon dioxide in the atmosphere.

• Deforestation decreases the amount of carbon dioxide in the atmosphere.

• Deforestation has no impact on the amount of carbon dioxide in the atmosphere.

• Deforestation has very little impact on the amount of carbon dioxide in the atmosphere.

Ice samples from glaciers provide evidence that today's atmosphere contains more carbon dioxide than ancient atmospheres on Earth did. Why is this increase in carbon dioxide a concern to scientists?

• It contributes to the rapid expansion of continental glaciers.

• It contributes to the rapid cooling of the warm ocean currents

• It contributes to the gradual warming of the atmosphere

• It contributes to the loss of radiant energy from the sun.

This data set shows that

• there is more CO2 in the atmosphere now than ever before (since we have data records)

• Hawaii will be most affected by global warming

• global temperatures are rising

• there is more CO2 in Hawaii than anywhere else

This data set shows that

• there is more CO2 in the atmosphere now than ever before

• Hawaii will be most affected by global warming

• global temperatures are rising

• there is more CO2 in Hawaii than anywhere else

Students observe these two graphs. The first graph shows the change in carbon dioxide (CO2) in the atmosphere from 1880 to 2000. The second graph shows the change in global temperature in degrees Celsius (C) from 1880 to 2000. After observing the graphs, the students suggest different ways to decrease the rate of global climate change. What question should students ask to determine which suggestions will be most helpful?

• What country is emitting the most carbon dioxice?

• How much carbon dioxide can the atmosphere hold?

• How does increasing global temperature cause carbon dioxide levels to rise?

• What human activities are producing carbon dioxide that is released into the atmosphere?

Study the graph. What is the y-axis label?

• CO2 Concentration (ppm)

• Year

• UC San Diego

• Carbon Dioxide Concentration at Mauna Loa Observatory

The amount of carbon dioxide in Earth's atmosphere has dramatically increased since the Industrial Revolution.

• True, It has now reached 400 ppm.

• False, It has remained in the range of the natural cycle.

Climate researchers are creating a computer simulation to help them understand changes in the Earth system. They want to use the simulation to see what happens when they increase the carbon dioxide in the atmosphere. What should their simulation show about energy absorbed by Earth’s surface? When carbon dioxide in the atmosphere increases, the amount of energy absorbed by Earth’s surface should...

• increase.

• decrease.

• stay at a constant level.

• change unpredictably.
