CNN reported this month that 40% of the ozone layer over the Arctic was depleted from December 21st, 2010 to March 31st, 2011 — roughly three months. I heard a CNN anchor report this, with some alarm. The clip provides confirmation. I also watched as this anchor continued, after a few sentences on this, to another news item — about an unrelated business development or some such. Guess life on this planet not as big a deal.
Ozone depletion over Arctic ‘unprecedented’ this winter
April 05, 2011|By the CNN Wire Staff
The depletion of the ozone layer over the Arctic region “has reached an unprecedented level,” a loss of 40% from the beginning of the winter to late March, the U.N. weather agency said Tuesday.
The World Meteorological Organization blames the “record loss” on the “continuing presence of ozone-depleting substances in the atmosphere” and a “very cold winter in the stratosphere.”
The ozone layer is the “shield that protects life on Earth from harmful levels of ultraviolet rays,” the organization said.
