            "description": "Good news: The next three decades will see an end to the era of big ozone holes. NASA scientists report in a new study that the Antarctic ozone hole will be consistently smaller than 8 million square miles by the year 2040. Man-made chemicals in the atmosphere cause a hole to form in the ozone layer over Antarctica each year. Although emissions of these chemicals have been declining in recent years thanks to the 1989 Montreal Protocol, which bans the production of ozone-depleting substances, max ozone hole sizes have remained larger than 8 million square miles since the early 1990s. Using data collected by NASA’s Aura satellite, scientists were able to determine how chemical levels in the ozone hole varied each year, and predict how hole sizes would change in the future.

            "description": "The next three decades will see an end of the era of big ozone holes. In a new study, scientists from NASA Goddard Space Flight Center say that the ozone hole will be consistently smaller than 8 million square miles by the year 2040.Ozone-depleting chemicals in the atmosphere cause an ozone hole to form over Antarctica during the winter months in the Southern Hemisphere. Since the Montreal Protocol agreement in 1987, emissions have been regulated and chemical levels have been declining. However, the ozone hole has still remained bigger than 8 million square miles since the early 1990s, with exact sizes varying from year to year.The size of the ozone hole varies due to both temperature and levels of ozone-depleting chemicals in the atmosphere. In order to get a more accurate picture of the future size of the ozone hole, scientists used NASA’s AURA satellite to determine how much the levels of these chemicals in the atmosphere varied each year. With this new knowledge, scientists can confidently say that the ozone hole will be consistently smaller than 8 million square miles by the year 2040. Scientists will continue to use satellites to monitor the recovery of the ozone hole and they hope to see its full recovery before the end of the century.Research: Inorganic chlorine variability in the Antarctic vortex and implications for ozone recovery.Journal: Geophysical Research: Atmospheres, December 18, 2014.Link to paper: http://onlinelibrary.wiley.com/doi/10.1002/2014JD022295/abstract.Here is the YouTube video. || ",
