The same destructive process that opened a hole in the Earth's protective ozone layer over Antarctica is operating in the arctic, the head of Canada's ozone research team says. Wayne Evans said Wednesday there was a "crater" of ozone depletion over Scandinavia during the first week of February, larger and deeper than a crater discovered in 1986. The result of a thinner ozone layer is increased penetration of the sun's ultraviolet radiation, leading to increased skin cancer, eye damage and damage to crops. "All through January, we saw the cold temperatures, actual ice clouds and now that sunlight has become available, we saw actual destruction of ozone," Evans said.
