This issue's “Curated Spaces” section comprises a photo essay with photographs from his ten-year project, “World View of Global Warming,” and the resulting book, Earth under Fire: How Global Warming Is Changing the World (2007). In his corresponding essay, Matthew Gandy, the author of Concrete and Clay: Reworking Nature in New York City (2002), investigates the historical linkages between nature and cities in the southern and northern reaches of the world, reminding readers that environmental justice is not only rooted in the local but also blossoms transnationally.
