Final answer:
The order of the citations should be based on alphabetical order by the author's last name or by the title when no author is given. The correct order is 5, 2, 1, 3, 4, 6. The citations cover various aspects of global warming from scientific, social, and political perspectives, in the context of Social Studies.
Step-by-step explanation:
The question relates to the proper ordering of citations, which might suggest an English or Social Studies assignment focusing on environmental issues, particularly climate change and global warming. However, the inclusion of information about environmental history and the role of figures like Al Gore suggests the primary subject is Social Studies.
The citations provided should be ordered alphabetically by author's last name or title when no author is present. The correct order would be 5, 2, 1, 3, 4, 6, as shown below:
