Ozone

A wildfire can send smoke into the stratosphere, where it can linger for up to a year. According to a new MIT study, these particles can cause chemical reactions that erode the protective ozone layer

Earth's protective ozone layer is slowly but noticeably healing at a pace that would fully mend the hole over Antarctica in about 43 years, a new United Nations report says. A once-every-four-years scientific assessment found recovery in progress, more than 35 years after every nation in the world agreed to stop producing chemicals that chomp on the layer of ozone in Earth's atmosphere that shields the planet from harmful radiation linked to skin cancer, cataracts and crop damage. In the upper stratosphere and in the ozone hole we see things getting better," said Paul Newman, co-chair of the scientific assessment. The progress is slow, according to the report presented Monday at the American Meteorological Society convention in Denver. The global average amount of ozone 18 miles (30 kilometers) high in the atmosphere won't be back to 1980 pre-thinning levels until about 2040, the report said. And it won't be back to normal in the Arctic until 2045. Antarctica, where it's so thin ..

Extremely large volcanic eruptions called might significantly warm Earth's climate and devastate the ozone layer that shields life from the Sun's UV radiation, suggests a new NASA climate simulation.

The ozone layer may be heating the Earth's atmosphere more than previously thought by weakening one of our planet's most important cooling mechanisms, according to a study

The research has also revealed that ozone in the lower atmosphere, in particular, contributed to warming in the southern ocean

Researchers cautioned that if major fires became more frequent with a changing climate, more damaging ultraviolet radiation from the sun will reach the ground.

The ozone count in central Kolkata was 60 per cent more than the safe levels, raising concerns about public health and the threat it poses to the iconic Victoria Memorial.

It has the potential of an immunity-boosting prophylactic and can help ease post-Covid-19 complications
