Large Hole in the Arctic Ozone Layer Is Now Closed
By Jessica
Stewart on April 29, 2020
I n a victory for the planet, a
large hole in the ozone layer has closed up on its own. Located over the
Arctic, it first formed in mid to late March and was one of the largest ozone
holes the area had ever seen. As the ozone is responsible for absorbing the
sun's UV rays, its health is of the utmost importance to our planet. That's
what makes the hole's closure such a relief.
To be clear, the hole's appearance and
repair were not caused by human activity. Scientists from Copernicus Atmosphere Monitoring
Service (CAMS), who have been monitoring the area, attribute
the ozone hole to something more natural. A large low-pressure area made from
swirling cold air—known as a polar vortex—was particularly strong for several
weeks in March. This caused cold air to remain trapped in the North Pole, the
by-product of which was the formation of high altitude clouds that cause
chemical reactions to stimulate ozone depletion once sunlight returns.
So, now that the polar vortex is starting to
break down, the air between the ozone-depleted and ozone-rich layers are mixing
once again. This has caused the hole to heal itself as ozone levels begin to
rise once again. This is great news, as the Arctic doesn't typically have as
much ozone depletion as the Antarctic ozone layer. It's this area that most
people are familiar with, as the 1985 discovery of a hole over the South Pole
caused big changes in aerosols and refrigerants.
Interestingly, there's also good news about
this ozone hole. Thanks in good part to measures taken as part of the Montreal
Protocol, a 1987 accord that phased out manmade chemicals harming the ozone,
the Antarctic ozone hole is shrinking. These changes, coupled with variations
in the Southern Hemisphere's air patterns, have contributed to the slow closing
of the hole.
In a win for the planet,
an ozone hole over the Arctic has now closed.

Delta adds new service to Greece
·
Starting July 2nd, Delta will
fly to Athens International Airport (ATH) from its largest
hub at Hartsfield-Jackson International Airport (ATL) with a
daily service. This route was last served in 2011 and will allow the airline to
offer connections to over 140 cities across the US from its largest hub.
