Human Activities and Global Climate Change CFA

A steady increase in global temperature has been recorded between 1900 and today. Before concluding that this rise in temperature is the result of the increased burning of fossil fuels since that same time, which of the following questions would have to be answered?

• What is the CO₂ content in one metric ton of fossil fuels?

• Which gases are released when burning fossil fuels?

• What, if any, temperature rise was occurring prior to 1900?

• How have humans adapted to temperature change?

The graph shows data on the carbon dioxide emitted when producing different foods. Which of the following claims is supported by the data?

• The highest carbon emissions come from the production of dairy products.

• Producing 1 lb of carrots results in more CO₂ emissions than producing 1 lb of tomatoes.

• Producing food from plants results in more carbon dioxide emissions than from animals.

• Carbon emissions are higher for the production of beef than for chicken and pork combined.

The burning of fossil fuels contributes to the addition of greenhouse gases to the atmosphere. These gases trap thermal energy in the earth’s atmosphere. Which of the following would be the most reasonable changes that could result from an increase in the burning of fossil fuels?

• The air all over the globe would become dirtier

• There would be a global rise in temperatures

• Ecosystems would become more diverse

• Rates of photosynthesis would decrease

What evidence would support the claim that an increase in human population contributes to the emission of greenhouse gases?

• Data showing that greenhouse gas production has leveled off once the global population reached a certain number

• Data showing that the amount of greenhouse gases produced varies with the level of development a country has reached

• Data showing that greenhouse gas emissions for each individual human has dropped over the last thirty years

• Data showing that the ten countries with the largest populations are the ten countries that produce the most greenhouse gases
