Exoplanet atmosphere characterization has the potential to reveal the origins, nature, and even habitability of distant worlds. In this talk, I will present work that is a step toward realizing that potential for a diverse group of four extrasolar planets. I will focus on results from recent, intensive observational campaigns with the Hubble and Spitzer Space Telescopes, including measurements of atmospheric water abundance, global climate maps, and the discovery of clouds. Taken together, these results provide a foundation for comparative planetology beyond the Solar System and the investigation of Earth-like, potentially habitable planets with future observing facilities.
