New study claims ozone hole might not be recovering as previously thought
A new study has found the ozone layer hole over the Antarctic seems to be getting larger, contradicting the previous reports which claimed it is recovering.
Ozone layer recovery is on track, due to success of Montreal Protocol
New York: The Earth’s ozone layer is on track to recover within four decades, a UN-backed panel of experts said on Monday.
Global cooperation to protect the ozone layer can ensure a better future for us all
New York: As the Montreal Protocol to Protect the Ozone Layer turns 35 on Friday, World Ozone Day, the United Nations has said that continuing the level of cooperation that led to the treaty’s adoption and success is just what is needed to protect life on Earth, end the climate crisis and ensure a brighter future for us all.
Act now to slow climate change and protect the planet, urges UN chief
New York: The ozone layer – a fragile shield of gas that protects the Earth from the harmful rays of the sun – is “on the road to recovery”, the UN chief said on Thursday in his message for the World Ozone Day.
Ozone treaties ‘inspiring examples’ of political will, UN chief says on International Day
New York: The United Nations commemorated the International Day for the Preservation of the Ozone Layer, on Wednesday, recognizing the success of landmark global agreements in helping restore the protective layer around Earth.
Ozone levels increased during lockdown, says CSE’s new analysis of air pollution levels
New Delhi/IBNS: While most people were happy with the decrease in the overall air pollution level during the national lockdown imposed to contain the spread of COVID-19 virus, it is not the complete picture, according to the Delhi-based Centre for Science and Environment (CSE).
Arctic observes alarming levels of ozone depletion
Geneva/UNI: Depletion of the ozone layer, the shield that protects life on Earth from harmful levels of ultraviolet radiation, reached an unprecedented level over large parts of the Arctic this spring, World Meteorological Organisation said on Saturday.
2019 Ozone hole is the smallest on record since its discovery
New York: The annual ozone hole reached its peak extent of 6.3 million square miles (16. 4 million square kilometers) on Sept. 8, and then shrank to less than 3.9 million square miles (10 million square kilometers) for the remainder of September and October, according to NASA and NOAA satellite measurements.
Ozone on track to heal completely in our lifetime, UN environment agency declares on World Day
New York: At the current momentum, scientists predict the planet’s protective shield of gas - or ozone layer as we know it - will be completely healed as far as some regions of the planet are concerned, by the 2030’s, the UN’s environmental agency (UNEP) revealed on Monday.
Healing of ozone layer gives hope for climate action: UN report
New York, Nov 6 (IBNS): The findings of a new UN-backed report, released on Monday, showing the ongoing healing of the ozone layer, are being hailed as a demonstration of what global agreements can achieve, and an inspiration for more ambitious climate action to halt a catastrophic rise in world temperatures.
Ozone hole could've been a big one this year – but it wasn’t: Finds study
New York, Nov 3 (IBNS): The ozone hole that forms over the Antarctic each September is primarily driven by two factors: the amount of ozone-destroying chlorine in the polar stratosphere and the availability of ice crystals in stratospheric clouds for the chlorine to bind to.
Now is a ‘pivotal time for climate action’ says UN chief, looking to ozone layer gains
New York, Sept 17 (IBNS): With record-breaking heat once again enveloping the earth this year, United Nations Secretary-GeneralAntónio Guterres said it was also “a pivotal time for climate action”, marking the International Day for the Preservation of the Ozone Layer, on Sunday.
The ozone layer continues to thin: Study
New York, Feb 6 (IBNS): The vital ozone layer has continued to deplete in recent years over the densely populated mid-latitudes and tropics, while it is recovering at the poles. This is documented by an international research team in the journal Atmospheric Chemistry and Physics.
NASA study: First direct proof of Ozone hole recovery due to chemicals ban
Washington, Jan 8 (IBNS): Measurements show that the decline in chlorine, resulting from an international ban on chlorine-containing manmade chemicals called chlorofluorocarbons (CFCs), has resulted in about 20 percent less ozone depletion during the Antarctic winter than there was in 2005 — the first year that measurements of chlorine and ozone during the Antarctic winter were made by NASA’s Aura satellite.
Warm air helped make 2017 Ozone hole smallest since 1988
Washington, Nov 4 (IBNS): Measurements from satellites this year showed the hole in Earth’s ozone layer that forms over Antarctica each September was the smallest observed since 1988, scientists from NASA and NOAA announced today.
