What percentage of greenhouse gases are produced by humans today?
What percentage of greenhouse gases were produced by humans in the early 1900s?
What other factors cause greenhouse gases?
What is the relationship between the concentration of greenhouse gases and temperature?

Write down three to five questions about human activities and climate change that will help you form your opinion about the subject. During your research, look for facts that will answer these questions. You will submit these questions when submitting your assignment.
