Abstract
Many lines of inorganic geochemical evidence suggest transient "whiffs" of environmental oxygenation before the Great Oxidation Event (GOE). Slotznickassert that analyses of paleoredox proxies in the Mount McRae Shale, Western Australia, were misinterpreted and hence that environmental Olevels were persistently negligible before the GOE. We find these arguments logically flawed and factually incomplete.
