“Columbia earthscape is an integrated, interdisciplinary resource that connects the Earth and environmental sciences with their social, political, and economic dimensions. Although it primarily serves undergraduates, it also functions as an online reference for graduate students, investigators, and professionals, as well as a core text and enrichment for high schools and continuing education.”
Earthscape deals with the global environment. It’s a very useful site directing researchers to conferences, seminars, books and journals; teachers to multidisciplinary, multimedia resources; students to study aids; and policy-makers to global, public online discussions.
