Major climate change milestone reached as gases behind ozone hole are cut for first time

A major milestone in the fight against climate change has been achieved as greenhouse gases, which were behind the hole in the ozone layer, have dropped for the first time.

Levels of harmful hydrochlorofluorocarbons (HCFCs), or greenhouse gases, which were developed as replacements for chlorofluorocarbons (CFCs), have reduced.

The international Montreal Protocol was agreed to in 1987 and aimed to introduce controls on the production and use of ozone-depleting substances (ODS), which were once widely used in the manufacture of hundreds of products, including refrigerators, aerosol sprays, foams and packaging.

While production of CFCs has been banned globally since 2010, HCFC production and usage is still being phased out.

A study, published in the Nature Climate Change journal on Tuesday, reveals reductions have been recorded for the first time. It is a significant development, author Luke Western, Marie Curie Research Fellow at the University of Bristol's School of Chemistry, told The National.

“This is a major milestone,” he said. “Our prediction is that it will continue to decrease. If this trend continues the ozone hole will recover in about 40 years' time.

“In terms of climate change this is very significant. The biggest message this shows is that environmental policies, like the Montreal Protocol, do work. It is the first time since monitoring began in the 1980s that we have seen a reduction.”

The international study, titled Global Reduction in Harmful Greenhouse Gases and Ozone-Depleting Substances: Success of Montreal Protocol Confirmed, shows the total amount of ozone-depleting chlorine contained in all HCFCs peaked in 2021.

Although the drop between 2021 and 2023 was less than 1 per cent, it still shows HCFC emissions are heading in the right direction.

“The results are very encouraging. They underscore the great importance of establishing and sticking to international protocols,” Dr Western said.

“Their production is currently being phased out globally, with a completion date slated for 2040. In turn, these HCFCs are being replaced by non-ozone-depleting hydrofluorocarbons (HFCs) and other compounds.

“By enforcing strict controls and promoting the adoption of ozone-friendly alternatives, the protocol has successfully curbed the release and levels of HCFCs into the atmosphere.

“Without the Montreal Protocol, this success would not have been possible, so it’s a resounding endorsement of multilateral commitments to combat stratospheric ozone depletion, with additional benefits in tackling human-induced climate change. It shows the success of international co-operation and the importance of it in tackling environmental issues.”

The results rely on high-precision measurements at globally distributed atmospheric observatories, using data from the Advanced Global Atmospheric Gases Experiment and the National Atmospheric and Oceanic Administration (NOAA).

“We use highly sensitive measurement techniques and thorough protocols to ensure the reliability of these observations,” said co-author Dr Martin Vollmer, an atmospheric scientist at the Swiss Federal Laboratories for Materials Science and Technology.

Co-author Dr Isaac Vimont, a research scientist at the NOAA in the US, said environmental monitoring is imperative.

“This study highlights the critical need to be vigilant and proactive in our environmental monitoring, ensuring other controlled ozone-depleting and greenhouse gases follow a similar trend which will help to protect the planet for future generations,” he said.

In December, Nasa launched a website, earth.gov, that will soon monitor locations around the world that are producing greenhouse gases.

Nasa administrator Bill Nelson revealed the details at a Future Talks event at the Museum of the Future in Dubai and said the website would use data from Nasa satellites to track greenhouse gases, which become trapped in the Earth’s atmosphere and cause the planet to heat up.

Hili 2: Unesco World Heritage site

The site is part of the Hili archaeological park in Al Ain. Excavations there have proved the existence of the earliest known agricultural communities in modern-day UAE. Some date to the Bronze Age but Hili 2 is an Iron Age site. The Iron Age witnessed the development of the falaj, a network of channels that funnelled water from natural springs in the area. Wells allowed settlements to be established, but falaj meant they could grow and thrive. Unesco, the UN's cultural body, awarded Al Ain's sites - including Hili 2 - world heritage status in 2011. Now the most recent dig at the site has revealed even more about the skilled people that lived and worked there.

No more lice

Defining head lice

Pediculus humanus capitis are tiny wingless insects that feed on blood from the human scalp. The adult head louse is up to 3mm long, has six legs, and is tan to greyish-white in colour. The female lives up to four weeks and, once mature, can lay up to 10 eggs per day. These tiny nits firmly attach to the base of the hair shaft, get incubated by body heat and hatch in eight days or so.

Identifying lice

Lice can be identified by itching or a tickling sensation of something moving within the hair. One can confirm that a person has lice by looking closely through the hair and scalp for nits, nymphs or lice. Head lice are most frequently located behind the ears and near the neckline.

Treating lice at home

Head lice must be treated as soon as they are spotted. Start by checking everyone in the family for them, then follow these steps. Remove and wash all clothing and bedding with hot water. Apply medicine according to the label instructions. If some live lice are still found eight to 12 hours after treatment, but are moving more slowly than before, do not re-treat. Comb dead and remaining live lice out of the hair using a fine-toothed comb.
After the initial treatment, check for, comb and remove nits and lice from hair every two to three days. Soak combs and brushes in hot water for 10 minutes.Vacuum the floor and furniture, particularly where the infested person sat or lay.
