Emissions of Ozone-Destroying Chemical Mysteriously Rising

A new study from the National Oceanic and Atmospheric Administration (NOAA) shows an "unexpected and persistent increase" in global emissions of an ozone-depleting chemical even though an international treaty forced production to completely halt by 2010.

NOAA scientists suggest that emissions are most likely from new, unreported production from an unidentified source in eastern Asia.

Ozone Layer Recovery Falters Unexpectedly

By Alex Kirby

The Earth's protective ozone layer is not recovering uniformly from the damage caused to it by industry and other human activities. And scientists are not sure why it isn't.

An international research team says the ozone, which protects humans and other species from harmful ultraviolet radiation, is continuing to recover at the poles. But recovery at lower latitudes, where far more people live, is not.

New Study Showing Ozone Recovery Hailed as Model for Tackling Climate Crisis

By Jake Johnson

Hailed as an example of how concerted global action can help solve a planetary crisis, a new study conducted by NASA scientists documented the first direct evidence that an international effort to ban chlorofluorocarbons (CFCs) has led to the recovery of the Antarctic ozone hole.

This Year's Ozone Hole Is the Smallest It's Been Since 1988

The hole in Earth's ozone layer is the smallest it's been since 1988, NASA satellite estimates observed.

While the ozone hole is still enormous—measuring about 19.6 million square kilometers (7.6 million square miles, or 2.5 times the size of the U.S.) at its annual peak extent this Sept. 11—that's much smaller compared to the average area of ozone hole maximums since 1991 of roughly 26 million square kilometers (10 million square miles).
