What is one example of how humans impact global warming?

• Contour plowing by farmers increases the level of rain water run-off.

• Burning coal and oil increases the level of carbon dioxide in the atmosphere.

• The use of copper wire in power transformers increases the speed of the electrical currents.

• Heat emitted from factories, automobiles, and buildings increases the average global temperature.

With less than 5% of the world's population, the United States emits 24% of the world's carbon emissions, while China with 20% of the world's population accounts for 12% of the world's carbon emissions. Based upon this information, what can be inferred about the impact of human population growth on global warming?

• Global warming will decrease as the human population increases.

• An increase in human population results in an increase in carbon emissions.

• There is a direct link between the expanding population and the increase in global warming.

• It is the types of human activities that contribute the most to global warming not just the expanding population.

• increase in the concentration of greenhouse gases

• decrease in the level of oxygen in the air

• increase in percent of oxygen in the air

• decrease in rainfall
