We’re highlighting a wide range of these good-news stories in a special WU microsite created in honor of Earth Day. The theme is progress: through a collection of articles by researchers, field experts, and scientists, the microsite outlines the current state of our climate, how humans can adapt in coming years, and the various ways that we can minimize the damage to our planet's precious ecosystem.
