Commission for the Conservation of Antarctic Marine Living ResourcesA. OverviewAntarctica is surrounded by an unbroken and dynamic body of water known as the Southern Ocean, which constitutes about 10% of the world's total ocean surface. For about 200 years, Antarctica's resources have been unsystematically harvested. In many cases the intense level of exploitation resulted in the severe ...

This computer image from October 1987 shows the thinning ozone layer over Antarctica. Photo by National Oceanic and Atmospheric Association In 1987, the countries of the world adopted the Montreal Protocol, which has since phased out 99 per cent of ozone-depleting substances and helped arrest the ozone layer’s decline.

Here’s a closer look at some of the most popular misconceptions around the climate crisis.

The recent collapse of a 1,100km 2 ice shelf in Antarctica came at a time of record high temperatures and is a symptom of a planet in climate crisis, experts say. The Conger ice shelf, which cleaved away from the eastern side of Antarctica in March, is the latest victim of rising temperatures at the ...

But in 1985, a hole was confirmed in the ozone layer over Antarctica. The world’s natural sun shield, which protects humans, plants, animals and ecosystems from excessive ultraviolet radiation, had been breached.

Human activities have had a major effect on the balance of the Antarctic marine ecosystem, this can be seen by damage of large agae such as kelp that is caused by increased UV penetration

NAIROBI, 9 January 2023 – The ozone layer is on track to recover within four decades, with the global phaseout of ozone-depleting chemicals already benefitting efforts to mitigate climate change. This is the conclusion of a UN-backed panel of experts, presented today at the American Meteorological Society’s 103rd annual meeting. Examining novel technologies such as geoengineering for the ...

Safeguarding the environment for future generations The United Nations Environment Programme (UNEP) is the United Nations’ leading global authority on the environment, driving transformational change on the triple planetary crisis: the crisis of climate change, the crisis of nature, land and biodiversity loss, and the crisis of pollution and waste. Since its founding in 1972, UNEP has served ...

By Mario Molina, Nobel Prize Laureate in Chemistry and Durwood Zaelke, President, Institute for Governance and Sustainable Development Ozone depletion was the first human threat to the global atmosphere to be recognized. It was also the first to be addressed by the international community. The results have been truly remarkable. The Montreal Protocol on Substances that Deplete the Ozone Layer ...
