Two nearby explosive massive star deaths, or supernovas, may have triggered mass extinction events in Earth's distant past, ...

In 1985, scientists discovered a seasonal hole in the Antarctic ozone layer. This protective layer shields Earth from harmful ultraviolet radiation. The sudden depletion raised global concerns, as ...

Operators follow a 25-year rule: at this point, a satellite’s mission is deemed to have ended and it is lowered into the atmosphere where gravity and friction kicks in. While this helps clear space, ...

In general, the conditions for ozone destruction on this scale just doesn't happen at the North Pole. This year, the strong and stable polar vortex has caused the concentration of more ozone ...

A recent study reveals that methane emissions could unexpectedly boost ozone layer recovery, particularly in the Arctic and ...

While the recovery of the ozone hole has been documented for a few years now ... Yet the problem of decline persists because ...

Arctic ozone fell to a historic low level due to unusual weather that allowed for greater than usual chemical ozone destruction. Although global warming and ozone depletion are caused by different ...

Although the Montreal Protocol has provided relief, anthropogenic emissions of another substance, nitrous oxide, are set to dominate ozone destruction. Figure 1: Influence of greenhouse-gas ...

i) Because we end up with Cl and Br and the net process is to convert ozone to oxygen, we get more ozone destruction than by the independent cycles only. This is especially true for Br because ...

Get Instant Summarized Text (Gist) Increases in methane emissions could significantly impact the recovery of the stratospheric ozone layer, especially in polar regions. Methane, while a potent ...

In densely populated coastal areas, reactions of polluted air with sea salt aerosol from the ocean can lead to high surface ozone levels that affect air quality. Chlorine has become infamous for ...
