Ozone hole on the mend – Expert reaction

John Kerr posted in on July 1st, 2016.

After persisting for decades, the hole in the ozone layer over Antarctica has begun to ‘heal’, exhibiting an ozone increase. New research from US and UK researchers, published in Science, reports that international efforts to control ozone-depleting chemicals are paying off. Regular and consistent increases in ozone have been detected using several different methods, giving […]

Supersized ozone hole avoided

Amy Guest posted in on May 29th, 2015.

The Montreal Protocol has prevented a supersized Antarctic ozone hole and a ‘full blown’ Arctic ozone hole, a new study has revealed. Scientists have modelled what the ozone layer would have looked like if ozone-damaging chemicals, known as chloroflurocarbons (CFCs), had not been banned by the 1989 Montreal Protocol. The research, published in Nature Communications this week, has predicted that […]

Ozone loss slows, new climate impacts loom – global report

Dacia Herbulock posted in on September 11th, 2014.

Destruction of the planet’s protective ozone layer is slowing, according to the latest scientific assessment, but full impacts on global climate are still coming clear. The first comprehensive update on global ozone in four years has been released today from the United Nations Environmental Programme (UNEP) and the World Meteorological Organisation (WMO). The Assessment for Decision-Makers, […]

Did saving the ozone layer ‘pause’ warming?

John Kerr posted in on November 11th, 2013.

The ban on ozone-depleting CFCs, under the Montreal Protocol, may have contributed to the recent hiatus in global surface temperature increases, say international scientists. The researchers add that their findings, published today in Nature Geoscience, help to link human actions over the past century with changes in the rate of warming. The study is based […]
