Imagine the year 2065. Two-thirds of
Earth's ozone is gone.
People living in mid-latitude cities like Washington, D.C., get sunburned after five minutes. DNA-mutating UV radiation is up 650 percent

Ozone is Earth's natural sunscreen, absorbing and blocking most of the incoming UV radiation from the sun and protecting life from DNA-damaging radiation
This time series from the ozone "World Avoided" model shows the concentration of ozone over the South Pole at four key times. Reds represent normal to high concentrations; blues show depleted areas
By the simulated year 2020, 17 percent of all ozone is depleted globally
By the end of the model run in 2065, global ozone drops 67 percent compared to 1970s levels.
