THE ozone layer above Scotland is thinner than at any point in the last ten years, according to new research which has prompted fresh concerns over skin cancer rates.

Levels of ozone, which play a crucial role in helping to filter out harmful ultraviolet rays from the sun, were thought to be rising after the systematic banning of the CFC chemicals which were damaging it.

But now experts believe global warming is changing conditions in the upper atmosphere and leading to a reduction in levels again.

Cancer experts warned yesterday that the results meant it was more important than ever for people to take precautions when in the sun.
