While the hole in the Earth's protective ozone layer is slowly healing, its recovery might have a downside, scientists say: Climate change could change wind patterns and send ozone from high in the atmosphere down to the surface, where it is a major component of smog.

The discovery of a hole in the ozone layer above Antarctica was announced by a team of British scientists in 1985. The cause of the hole was attributed to ozone-depleting chemicals like chlorofluorocarbons (CFCs), which were primarily used in cooling units and propellants. When CFCs reach the ozone layer, they release chlorine atoms that rip ozone apart and peel away layers of Earth's natural sunscreen.

Simulations of life without the ozone layer, which is located in the Earth's stratosphere, are not pretty. The stratosphere (the second layer of the Earth's atmosphere, just above the one in which we dwell, the troposphere) contains 90 percent of the Earth's ozone at altitudes between 6 and 31 miles (9.6 and 50 kilometers) above us, where it traps most of the sun's harmful ultraviolet (UV) rays before they can reach the Earth's surface.

Without this shield, we'd be sunburned within 5 minutes of exposure, according to NASA's Earth Observatory.

The Antarctic ozone hole is the closest real-life glimpse at a world without UV protection. Since its discovery in the 1980s, it has spread over parts of Australia, New Zealand, Chile and South Africa where the threats of skin cancer, cataracts, and damage to have raised concerns.

It might be better for future reference to include a snipet from the article which supports your title. The copied portion only talks about the hole itself and never mentions why the recovery has a negative effect.
