Amplify: Analyzing Gas and Temperature Data (ECC1.5)

Which time period's data would provide the best evidence?

• data from 1880 to 2014

• data from 1995 to 2014

• data from 2013 to 2014

For global average temperature, what is the trend or change?

• increasing (getting warmer)

• decreasing (getting cooler)

• no trend or change (neither warmer nor cooler)

Compare the trends for carbon dioxide and temperature in the graphs below. Do these graphs show the same trend?

• Yes

• No

Compare the trends for methane and temperature in the graphs below. Do these graphs show the same trend?

• Yes

• No

Compare the trends for sulfur dioxide and temperature in the graphs below. Do these graphs show the same trend?

• Yes

• No

Which of the following claims do you think might be supported by the graph evidence? (You may choose more than one.)

• Increasing carbon dioxide is causing temperature to increase and ice to decrease.

• Increasing methane is causing temperature to increase and ice to decrease.

• Decreasing sulfur dioxide is causing temperature to increase and ice to decrease.
