A new report from NASA says the ozone layer is improving, according to a recent post from the Environmental News Network. Data from NASA’s AURA satellite shows the largest hole in the ozone layer, over the Arctic, is 12 million square miles and getting smaller.
Concern for the ozone layer began in the 1980s when scientists determined that CFCs and other chemicals caused a number of holes to appear. Without preventive measures, the chemicals would have eventually dissolved the protective shield.
Fortunately, the Montreal Protocol was enacted to preserve the ozone layer. The protocol was an international agreement that worked to phase out CFCs gradually.
Based on the results from AURA, NASA researchers believe the hole could shrink to 8 million square miles by 2045. Additionally, the research suggests the ozone layer could be repaired by the end of this century.
