The world's ozone layer is on "the road to long-term recovery" despite a destructive volcanic eruption in the South Pacific, the World Meteorological Organization said on Tuesday, after efforts to phase out ozone-depleting chemicals.
On current trends, the ozone layer is on track to recover to 1980 levels by around 2066 over the Antarctic, 2045 over the Arctic and 2040 for the rest of the world, the United Nations agency said.
Though the volcanic eruption near Tonga in early 2022 led to a short period of accelerated depletion of ozone above Antarctica last year, driven by higher levels of atmospheric water vapor, overall losses were limited, it said in its annual ozone bulletin.
The ozone layer protects the earth from the sun's ultraviolet radiation, which is linked to skin cancer and other health risks.
The Montreal Protocol, which came into effect in 1989, agreed to phase out chlorofluorocarbons and other ozone-depleting substances, and its success "stands out as a powerful symbol of hope" at a time when multilateral cooperation has come under strain, Reuters quoted UN Secretary-General Antonio Guterres as saying in a statement.
CFCs have been largely replaced by hydrofluorocarbons, which do not cause ozone depletion but are a powerful climate-warming greenhouse gas.
Countries are now implementing the 2016 Kigali amendment to Montreal, which will phase down HFC production, and could avoid around 0.5 degrees Celsius of warming by 2100.
China remains the world's biggest HFC producer, with current capacity the equivalent of nearly 2 billion metric tons of carbon dioxide. About a quarter is exported.
China's environment ministry said on Monday it would soon publish a plan to better control HFC production. As a developing country, it is obliged to cut HFC consumption by 85% from 2013 to 2045.
China is cutting manufacturing quotas and cracking down on illegal production, but it warned this year it still "faces huge challenges" in phasing down HFCs, which are used by a wide range of different industries, many of which have struggled to find substitute products.

An Australian student missing for two weeks near the country's tallest mountain was found on Wednesday, after surviving by foraging for berries, drinking water from a creek and finding two muesli bars left behind by other hikers, police said.

Hadi Nazari, a 23-year-old university student from Melbourne, went missing from his group of friends on December 26 in the Kosciuszko National Park.

Nazari was found on Wednesday afternoon by a group of hikers who alerted the authorities, police in the state of New South Wales said.

“This is the fourteenth day we've been looking for him and for him to come out and be in such good spirits and in such great condition, it’s incredible," NSW Police Inspector Josh Broadfoot said.

The student was in "really good spirits" with no significant injuries, he added.

More than 300 people had searched for Nazari across rugged bushland, police said. The national park is home to the 2,228 meter (7,310 foot) Mount Kosciuszko.
