The Earth's ozone layer is on its way to recovering, thanks to decades of work to get rid of ozone-damaging chemicals, a panel of international experts backed by the United Nations has found.
that chemicals such as chlorofluorocarbons, used in manufacturing aerosol sprays and used as solvents and refrigerants, could destroy ozone.
. This established the phaseout of almost 100 synthetic chemicals that were tied to the destruction of the all-important ozone.on the progress of the Montreal Protocol, the U.N.-backed panel confirmed that nearly 99% of banned ozone-depleting substances have been phased out. In some places, it may take longer. Experts said that 1980-level recovery over Antarctica is expected by around 2066 and by 2045 over the Arctic."The impact the Montreal Protocol has had on climate change mitigation cannot be overstressed," said Meg Seki, executive secretary of the U.N. Environment Programme's Ozone Secretariat, in a statement."Over the last 35 years, the Protocol has become a true champion for the environment.

UN says ozone layer slowly healing, hole to mend by 2066Earth’s protective ozone layer is slowly but noticeably healing at a pace that would fully mend the hole over Antarctica in about 43 years, a new United Nations report says. A once-every-four-years scientific assessment found recovery in progress, more than 35 years after every nation in the world agreed to stop producing chemicals that chomp on the layer of ozone in Earth’s atmosphere that shields the planet from harmful radiation linked to skin cancer, cataracts and crop damage. “In the upper stratosphere and in the ozone hole we see things getting better,' said Paul Newman, co-chair of the scientific assessment.
