Record Depletion of Arctic Ozone Layer Causing Increased UV Radiation in Scandinavia

[...]
"Such massive ozone loss has so far never occurred in the northern hemisphere, which is densely populated even at high latitudes," AWI researcher Markus Rex describes the situation. The ozone layer protects life on Earth's surface from harmful solar ultraviolet radiation. Because of the low inclination angle of the sun, exposure to ultraviolet radiation is not normally a public health concern at high northern latitudes. However, if ozone-depleted air masses drift further south over Central Europe, south Canada, the US, or over Central Asiatic Russia, for example, the surface intensity of UV radiation could lead to sunburn within minutes for sensitive persons, even in April.
Whether and when this may occur can be forecasted reliably only in the short term. People should thus follow the UV forecasts of regional weather services. "If elevated levels of surface UV occur, they will last a few days and sun protection will be necessary on those days, especially for children," Rex recommends.
