Underscoring the direness of the climate crisis, Oliver Ressler’s “Dog Days Bite Back” opens at Belvedere 21 in Vienna. Featured are works spanning photography, film, and installation by the Austrian artist that lament the state of stalled climate policy and fossil fuel crony capitalism run amok. His 2-channel video installation Climate Feedback Loops (2023, image), for example, starkly documents the ice melt around Svalbard, a Norwegian archipelago that is rapidly disappearing into the Arctic Ocean.
