Ozone Hole Over Antarctic Reaches Record Size, Threatens Global Health

The video discusses the current state of the ozone layer, highlighting that the hole over the Antarctic has reached a size comparable to the 2000 record. It explains the role of colder temperatures in this expansion and notes similar, though less severe, thinning over the Arctic. The video recounts the 1985 alarm that led to global efforts to reduce CFCs, which harm the ozone layer. Recent data from 2003 shows the hole has grown, exposing regions to increased UV radiation, which poses health risks. Despite a significant drop in CFC usage, concerns remain about the annual thinning of the ozone layer.
