Supporting Data of Global Warming

Greenhouse gases are important to our planet's survival because...

• They create a natural cooling effect that keeps us from burning up.

• They fuel the cars we drive.

• They create oxygen which we need to breathe.

• They keep our earth warm so we can sustain life.

The graph shows CO2 emissions and temperatures from 1909 to 1949. What conclusion is best supported by the graph?

• There is no relationship between carbon dioxide concentrations and temperatures

• As carbon dioxide concentrations increase, temperatures increase

• As carbon dioxide concentrations increase, temperatures decrease

• As carbon dioxide concentrations decrease, temperatures increase

This is a graph produced by the National Aeronautics and Space Administration (NASA). It tells us...

• that atmospheric carbon dioxide has massively increased since 1950.

• the independent variable is years before today.

• that atmospheric carbon dioxide is at its highest point in the past 800,000 years.

• the dependent variable is the amount of carbon dioxide in the atmosphere.

What is the greenhouse effect?

• A natural process where gases trap heat in the atmosphere.

• A man-made process where gases trap heat in the atmosphere.

• A natural process where the ocean traps heat in the atmosphere.

• A man-made process where the ocean traps heat in the atmosphere.
