Health warning as record low temperatures thin ozone layer

RECORD low temperatures over the North Pole are thinning the protective ozone layer, which could have repercussions for the health of those living in Scandanavia and Europe the EU warned yesterday.

"Large ozone losses are expected to occur if the cold conditions persist," said European Commissioner for Science and Research Janez Potocnik. He said the first signs of ozone loss have been observed after an extremely harsh winter above the Arctic.

The ozone layer keeps out ultraviolet radiation, which is dangerous to humans and animals. Less protection could increase risks of skin cancer and affect biodiversity, scientists say.

Because of the record lows over the Arctic, scientists have been put on alert to monitor the ozone layer over the coming months.

"The meteorological conditions we are now witnessing resemble and even surpass the conditions of the 1999-2000 winter when the worst ozone loss to date was observed," said Dr Neil Harris of the European Ozone Research Coordinating Unit in Britain.

He said temperatures at a 12-mile height had dropped to an average of minus 80C the lowest over the Arctic in half a century.

People in some northern countries who work out in the open should take special precautions to protect themselves from exposure to the sun, Dr Harris said.

"The Arctic appears to be moving into Antarctic-like conditions which will result in an increase in UV radiation levels that will have consequences on human health in northern hemisphere countries," the EU head office said.
