Global Change Explorer (GCX)

EPA's Global Change Explorer (GCX) is a collection of web tools that allow visualization, comparison, and access to spatial data that describe potential future environmental change. These data can serve as a starting point to assess the vulnerability of air, water, ecosystems, and human health to climate change, land use change, and other large-scale environmental stressors. The data and tools in the Global Change Explorer are relevant across multiple scientific disciplines and environmental media, providing a foundation for integrated assessments of global change.
