Human Carbon Emissions

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.
(See Attached Graph)
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 pie chart shows percentages of carbon dioxide (CO2 ) emissions by sector.

The burning of fossil fuels contributes to the addition of greenhouse gasses 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
