    Ozone for life: 35 years of ozone layer protection

    Thanks to the Montreal Protocol, the ozone layer is healing and expected to return to pre-1980 values by mid-century

    This year, we celebrate 35 years of the Vienna Convention and 35 years of global ozone layer protection. Life on Earth would not be possible without sunlight. But the energy emanating from the sun would be too much for life on Earth to thrive were it not for the ozone layer. This stratospheric layer shields Earth from most of the sun’s harmful ultraviolet radiation. Sunlight makes life possible, but the ozone layer makes life as we know it possible.

    International Day for Protection of the Ozone Layer, 16 September

    In 1994, the UN General Assembly proclaimed 16 September the International Day for the Preservation of the Ozone Layer

    The ozone layer, a fragile shield of gas, protects the Earth from the harmful portion of the rays of the sun, thus helping preserve life on the planet. The phase-out of controlled uses of ozone-depleting substances and the related reductions have not only helped protect the ozone layer for this and future generations but have also contributed significantly to global efforts to address climate change; furthermore, it has protected human health and ecosystems by limiting the harmful ultraviolet radiation from reaching the Earth.

    Chinese home insulation blamed for gas emissions damaging the ozone layer

    The EIA says that its estimates of the amount of the gas being used in China are in the middle of the emissions range calculated by scientists in their report in May.

    Cut-price Chinese home insulation is being blamed for a massive rise in emissions of a gas, highly damaging to the Earth's protective ozone layer. The Environmental Investigations Agency (EIA) found widespread use of CFC-11 in China, even though the chemical was fully banned back in 2010.

    Someone is cheating with ozone warn scientists: rate of decline has fallen drastically

    The ozone layer in the stratosphere, 10-to-40 kilometers above Earth's surface, protects life on the planet from deadly ultraviolet radiation.

    The decline in the atmosphere of an ozone-depleting chemical banned by the Montreal Protocol has recently slowed by half, suggesting a serious violation of the 196-nation treaty, researchers revealed Wednesday.

    Falklands’ linked scientist who helped identify ozone layer hole has died

    The British Antarctic Survey scientist Joe Farman, who helped identify the “hole” in the ozone layer over the southern pole, has died. Dr Farman who was also a scientific officer at the Falkland Islands Dependency Survey, published the discovery with Brian Gardiner and Jon Shanklin in the Journal Nature in 1985.

    Ozone layer future recovery linked to climate change, says reports

    A return to pre-1980 levels of ozone is expected around mid-century

    A report sponsored by the UN Environment Program finds that over the past decade, global ozone levels, and ozone levels in the Arctic and Antarctic regions are at a turnaround point -- no longer decreasing but not yet increasing.
