The dark black sky of the polar region in winter is not only the backdrop for the northern aurora bands, but also the presence of an equally natural phenomenon named nacre cloud.

A recent study shows that the ozone layer in the Antarctic is beginning to shrink.

In recent months, many regions in Vietnam and the world are constantly experiencing prolonged heat and drought, making us think of the global warming of the greenhouse effect.

Despite being nearly the same size as North America, the hole in the Antarctic ozone layer is still the second smallest gap in the past two decades.

Xinhua quoted Geir Braathen, a WMO expert, saying that in the past decade, the stratospheric ozone layer in the Arctic and Antarctic regions as well as globally has not decreased

The UNEP report stated that Asia-Pacific produces up to 85% and consumes 74% of HCFC produced and consumed globally, of which China is a producer, consumer and supplier of HCFC.

Scientists discovered ozone holes in Antarctica that are in the process of self-sufficiency, at least a decade earlier than they had previously expected.
