Ozone losses increase possible UV impacts
Total Ozone Mapping Spectrometer (TOMS) satellite measurements indicate that total ozone amounts have decreased in the Arctic over the past two decades. The average total ozone in March 1997 is 21% lower than the pre-1990s March average (figure courtesy of NASA). Eskimo sunglasses made of wood, bone...

Summary: | Total Ozone Mapping Spectrometer (TOMS) satellite measurements indicate that total ozone amounts have decreased in the Arctic over the past two decades. The average total ozone in March 1997 is 21% lower than the pre-1990s March average (figure courtesy of NASA). Eskimo sunglasses made of wood, bone,or leather have been found in the archaeological assemblages of several arctic cultures. The narrow slats over the eyes protect the wearer from snowblindness. These widespread and ancient artifacts indicate that arctic indigenous people have known for generations about the harmful effects of ultraviolet (UV) radiation. Although the sun never rises far above the arctic horizon, reflections from ice and snow surfaces can allow damaging levels of UV to reach unprotected eyes and vertical |
