  "The properties of ice make it particularly well suited to catalysing chlorine activation and to removing nitrogen oxides at the low temperatures of the stratosphere, but there are clues that other particle types might also have a role. The powerful eruption of Mount Pinatubo in the Philippines in 1991 injected large amounts of sulfur dioxide gas into the stratosphere. After being transported long distances and oxidized, this gas became a layer of reflective sulfuric acid particles over much of the globe. In addition to reducing global average surface temperatures by 0.5 °C for more than a year, these particles also catalysed ozone loss in the stratosphere — not just over polar regions, but throughout the mid-latitudes" (cites Brasseur, G. & Granier, C.
