Sometimes shows that take on political topics have the character of earnest class projects in a high-school corridor, but that was hardly the case with Weather Report: Art and Climate Change, a mammoth show organized by curator and art theorist Lucy Lippard. It not only filled the Boulder Museum of Contemporary Art to capacity, but spilled over to the Boulder Public Library and various other places. Lippard tapped some of the most famous environmental artists in the world along with Colorado artists of the same ilk. The resulting show was as provocative as it was beautiful.
