Global efforts to protect the ozone could work, the report said Environment

A 31-year global agreement to reduce ozone depleting chemicals could finally pay off, according to a new report. Last week, the National Oceanic and Atmospheric Administration reported that there was a hole in the ozone. Above Antarctica, September was not as big as 20 years ago. Ozone is a layer above the surface that acts "like a sunscreen" to protect …

Ozone layer hole will completely heal within 50 years & # 39;

(CNN) – The hole in the Earth's ozone layer should be completely cured within 50 years, climate change experts predict in a new UN report. The ozone layer is a fragile gas shield around the planet protecting animal and plant life from the strong ultraviolet (UV) rays of the sun. When the ozone layer is weakened, more UV rays can …

Ozone hole modest despite optimal conditions for ozone depletion

The ozone hole that formed in the upper atmosphere of the Antarctic each September was slightly above average in 2018, reported NOAA and NASA scientists. Above-average low temperatures in the Antarctic stratosphere created ideal conditions for the destruction of ozone this year, but a decline in ozone-depleting chemicals prevented the hole from being as large as it would have been …

Humble ozone hole despite optimal exhaustion conditions, scientists claim

Source: AP Modest ozone hole despite optimal conditions of exhaustion Although temperatures in the Antarctic stratosphere had created on average below average temperatures ideal conditions for the destruction of ozone in 2018, the decrease in the boreholes prevented the hole scientists NASA and the National Oceanic and Atmospheric Administration (NOAA) have shown that they were as big as 20 years …

Banned Ozone Depleting Chemical was used illegally in China

A dangerous ozone-depleting compound is still used in China, despite being banned worldwide by the Montreal Protocol, a new study finds. East China has emitted significant amounts of this substance – known as carbon tetrachloride (CCl4) – which is known to eat ozone, a protective layer in the earth's atmosphere that protects the world from dangerous ultraviolet radiation. The new …

Location of the great mysterious source of the banned ozone depleting substance revealed

The compound, carbon tetrachloride, contributes to the destruction of the Earth's ozone layer, which protects us from harmful ultraviolet radiation. As a result, the production of carbon tetrachloride since 2010 is banned worldwide will result in its release to the atmosphere . However, recent studies have shown that global emissions have not declined as expected, with some 40,000 tonnes still …
