FfFfFfFF 58,148 Posted April 28, 2020 Share Posted April 28, 2020 An “unprecedented” hole in the ozone layer which developed to become the largest ever seen over the Arctic has closed just weeks after opening, scientists observing the phenomenon have said. The gap in the vital layer, which protects the Earth from harmful radiation from the sun, set a new record for ozone depletion in the northern hemisphere when it formed earlier this month. The depleted area was roughly the size of Greenland, and stretched over the top of the polar icecap. CAMS said the hole had been caused by unusual weather patterns over the Arctic. Particularly cold temperatures and powerful winds formed a “polar vortex”, creating the frigid conditions which led to vast ozone depletion. The CAMS scientists added: “This ozone hole was basically a symptom of the larger problem of ozone depletion, and closed because of local annual cycles, not long-term healing. But, there’s hope: the ozone layer is also healing, but slowly.” *not Coronavirus-related https://www.independent.co.uk/environment/arctic-ozone-hole-closes-size-a9487961.html Link to post Share on other sites More sharing options...
