The year is 2065. Nearly two-thirds of Earth's ozone is gone -- not just over the poles, but everywhere. The infamous ozone hole over Antarctica, first discovered in the 1980s, is a year-round fixture, with a twin over the North Pole. The ultraviolet (UV) radiation falling on mid-latitude cities like Washington, D.C., is strong enough to cause sunburn in just five minutes. DNA-mutating UV radiation is up 650 percent, with likely harmful effects on plants, animals and human skin cancer rates.
Every pool of bright people should be working on a solution.
Every University, Cern, Darpa etc should be working, primary on the recovery of the ozone layer.

"We simulated a world avoided," said Newman, "and it's a world we should be glad we avoided."
So it's even worse?
The hole fluctuates in size from year to year. It's typically at its largest after the cold of winter and smallest after summer. (The seasons are opposite in the Southern Hemisphere). The WMO stressed that temperatures in the Antarctic stratosphere vary each year, so some years the ozone hole is relatively small and other years relatively large.
The large size of the hole this year does not reverse the projected long-term recovery of the ozone layer in the coming decades. Full recovery of the ozone layer should occur by around 2070, according to the WMO
False. In 2009 there was a computer simulation which showed that if CFCs had not been banned, two thirds of the ozone would be gone in 2065
But it's their report that claims that 66% of the ozone-layer has gone.
That was in 2009.

False. In the winter of 2015 the size of the Antarctic ozone "hole" was near record size. That is very different from "Worse diminishing ever of the ozone-layer."
Worse diminishing ever of the ozone-layer in 2015.
