With more than half of the current congress skeptical about climate change despite overwhelming scientific evidence for rising temperatures, sea levels, and severe weather patterns, it's nice to know that at least the Environmental Protection Agency still has a head on its shoulders. This website offers clear indications of how global warming will impact our food supply, water resources, infrastructure, ecosystems, and health. The hidden gem is a series of slideshows answering the question: How do climate models work? Readers can learn about models and scenarios, how they are tested, and how they diagnose the past and estimate the future.
