Climate scientist: “It’s already worse than what I imagined”

AMBER WAVES OF GRAIN. This field of ceramic nose-cones represents, in miniature, all the warheads in the US nuclear arsenal at the height of the Cold War, along with the nuclear submarines, bombers, and ballistic missiles designed to deliver them. Estimates put the warhead count at around 25,000. Denver sculptress Barbara Donachy created this installation to show what such a concentration of nuclear weaponry would look like all in one place. Her display contains 33,561 pieces representing 31,000 warheads, 1,799 ballistic missiles, 324 intercontinental bombers, and 37 nuclear submarines.

Smolny College Commencement, 2019. Smolny College—the first liberal arts program in Russia—was founded as a dual-degree program between Bard College in the United States and St. Petersburg University in Russia. Last month, the Russian State Prosecutor’s Office labeled Bard College “undesirable,” which criminalized Bard’s decades-long partnership with St. Petersburg University. Photo credit: Bard College.
