The Earth’s protective ozone layer is well on track to recovery thanks to a highly successful environmental agreement which marks it 30th anniversary on 16 September. The Montreal Protocol on Substance which Deplete the Ozone Layer achieved a near 99 per cent phase-out of ozone destroying substances like chlorofluorocabons (CFCs) which were once commonly used in products ranging like refrigerants and aerosols.

Countries are meeting in Montreal this week to mark the 30th anniversary of the world’s most successful ever environment agreement, which halted the destruction of the protective ozone layer. The 197 parties to the Montreal Protocol on Substances which Deplete the Ozone Layer are gathered in the Canadian birthplace of the treaty. This achieved a near 99 per cent phase-out of ozone destroying substances like chlorofluorocabons (CFCs) and hydrochlorofluorocarbons (HCFCs), once commonly used in products ranging like refrigerants and aerosols.

Air quality regulations and anti-pollution measures in Europe and North America have had very positive impacts on air quality. Since the year 2000, both average and peak surface ozone concentrations have levelled off and even started to fall at some locations after increasing throughout the twentieth century, according to a new report from the World Meteorological Organization.

The World Meteorological Organization has joined the global commitment to reduce deaths due to air pollution by two thirds by 2030. At the World Health Organization’s first ever Global Conference on Air Pollution and Health , WMO pledged to strengthen the quality and availability of pollution observations, enable provision of air quality forecast and advisory services and incorporate health impacts in key scientific assessments on climate and climate change.

Arctic sea ice has probably reached its annual minimum for 2018, according to the National Snow and Ice Data Center (NSIDC). Sea ice extent dipped to 1.77 million square miles (4.59 million square kilometers) on September 19, and again on September 23. After that, ice extent began to rise, signalling an end to the summer melt season.

An Arctic summer special observing period is taking place from 1 July to 30 September as part of the Year of Polar Prediction (YOPP). Extensive extra observations will be carried out at numerous land stations in the Arctic as part of field campaigns and expeditions, and by autonomous instruments. Numerical experimentation and internationally coordinated verification activities will use the additional observations for forecast evaluation and observational impact studies.

Top ozone experts from around the world highlighted the need for increased research and observations to inform policy on ozone and climate at a meeting sponsored by UN Environment and the World Meteorological Organization in Geneva, 28 – 30 March. The 10 th Ozone Research Managers (ORM) meeting concluded that integrated earth science observation systems are essential to ensure that action to protect the ozone layer also benefits the climate, given the complex and evolving interaction between the ozone layer and the climate system.
