The ozone layer is a part of Earth’s atmosphere that captures some of the Sun’s ultraviolet (UV) light emissions. When the ozone layer is compromised, its ability to absorb radiation weakens ...
In high school science class, textbooks often feature a recognizable image of the Earth and all its layers—currently, that’s the crust, outer and inner mantle, and outer and inner core.
If current policies remain, Earth’s ozone layer is expected to recover to values seen before ozone holes were were detected by about 2066 over the Antarctic, 2045 over the Arctic, and as soon as ...

The Grand Canyon is a gigantic geological library, with rocky layers that tell much of the story of Earth’s history. Curiously though, a sizeable layer representing anywhere from 250 million ...
In one of the great environmental success stories of our time, scientists say that a 35-year-old agreement has resulted in the steady and promising recovery of the Earth's ozone layer, a critical ...
Scientists have known about Earth’s ozone layer for over a century, but it wasn’t until the 1970s that they grew concerned about its integrity. Early in the decade, ...
