The Montreal Protocol The Montreal Protocol on Substances that Deplete the Ozone Layer is the landmark multilateral environmental agreement that regulates the production and consumption of nearly 100 man-made chemicals referred to as ozone depleting substances (ODS). When released into the atmosphere those chemicals damage the stratospheric ozone layer Earth?s protective shield that ...

 

In 1985 three British scientists published a paper in the journal Nature that revealed there was a large hole in the ozone layer above the Antarctic. The research sent shockwaves around the world. The ozone layer shields the planet from the sun?s harmful ultraviolet radiation and its loss would decimate life on Earth.

 

As greenhouse gas emissions hit new highs temperature records tumble and climate impacts intensify the Emissions Gap Report 2023: Broken Record ? Temperatures hit new highs yet world fails to cut emissions (again) finds that the world is heading for a temperature rise far above the Paris Agreement goals unless countries deliver more than they have promised. The report is the 14th edition ...

 

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.

 

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.

 

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 ...

 

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

 

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 ...
