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 ...

 

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

 

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 ...

 

If you?ve been following the global conversation around plastic pollution you?ve probably heard of microplastics. These small particles have turned up everywhere from the depths of the ocean to the top of Mount Everest and even throughout the human body. But what exactly are microplastics why ...

 

We work to protect and restore coastal ?blue carbon? ecosystems for the sustainable provision of ecosystem services to people and environment. Mangroves and seagrass meadows are coastal ecosystems that cover a small portion of the total ocean area but collectively are widely distributed on every continent except Antarctica. Mangroves are found in 123 countries worldwide with an estimated ...

 

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.

 

The remarkable story of the battle to save the ozone layer starts with science. In the mid-1970s scientists warned that man-made chemicals in everyday products like aerosols foams refrigerators and air-conditioners were harming the ozone layer. At that time they didn?t know the scale of the problem. But in 1985 a hole was confirmed in the ozone layer over Antarctica. The world?s ...

 

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.

 

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 ...
