The Montreal Protocol shows what is possible when science, diplomacy, and business cooperate to implement international environmental agreements. When the people became aware of a hole in the ozone layer over Antarctica—and damage to the protective layer of atmosphere around the world—leaders around the world coordinated action on ozone depleting …
HFCs could be responsible for emissions equivalent to 3.5 to 8.8 gigatons of carbon dioxide (Gt CO2eq) by 2050, according to this new UNEP report. The UNEP has released a report titled “HCFs: A Critical Link in Protecting Climate and the Ozone Layer,” on the importance of addressing hydrofluorocarbons (HFCs). …
This report addresses the mitigation of short-lived climate forcers (SLCFs) and its key role in air pollution reduction, climate protection and sustainable development. SLCFs are substances in the atmosphere that contribute to global warming and have relatively short lifetimes in the atmosphere. The focus is on three SLCFs – black …
A huge hole that appeared in the Earth's protective ozone layer above the Arctic in 2011 was the largest recorded in the Northern Hemisphere, triggering worries the event could occur again and be even worse, scientists said in a report on Monday. The ozone layer high in the stratosphere acts …
Try punching the air in front of you. Does it leave a hole? Surely not. But the ozone layer that exists in the stratosphere, the layer of the atmosphere just above us, does have a hole. Not quite technically perhaps. But in May 1985, Joseph Farman, Brian Gardiner and Jonathan …
Health officials are banning the only asthma inhaler sold over the counter in the United States starting from next year to prevent the use of products that harm the environment. The Food and Drug Administration said on Thursday that chlorofluorocarbons (CFCs) in metered-dose asthma inhalers that contain the drug epinephrine …
Proposed amendments to phase down hydrofluorocarbons (HFCs) under the Montreal Protocol received support from a diverse group of developing and developed countries during the Thirty-first meeting of the Open-ended Working Group of the Parties to the Montreal Protocol on "Substances that Deplete the Ozone Layer" (OEWG 31) held on 1-5 …
The environment ministry has targeted to phase out Ozone depleting HCFC by 2030, according to the Hydro Chlorofluorocarbons (HCFC) Phase out Management Plan. The plan will be implemented in 2013 in harmony with the Montreal Protocol in which Sri Lanka is a member country. Under the time frame, the HCFC …
London: Researchers in Australia have claimed that the hole in the ozone layer over Antarctica is on the road to recovery, 22 years after the Montreal Protocol to ban chlorofluorocarbons (CFCs) and related ozone-destroying chemicals came into force. The team is the first to detect a recovery in baseline average …
Shift in rainfall patterns across Southern Hemisphere The Antarctic ozone hole is about one-third to blame for Australia's recent series of droughts, say scientists. Writing in the journal Science, they conclude that the hole has shifted wind and rainfall patterns right across the Southern Hemisphere, even the tropics. Their climate …
This is the Presentation delivered by R Gopichandran, Environment and Climate Change Research Wing - Gujarat Energy Research and Management Institute, at International Conference on 'Compliance and Liability in Climate Change Negotiations' organized by CSE on 1 March 2011 at New Delhi. The presentation deals with International compliance mechanism, its …
India and the US on Friday set up a joint task force with the aim of reducing greenhouse emissions at a workshop on HydroFluoroCarbons (HFCs) attended by environment minister Jairam Ramesh and US deputy assistant secretary of state for environment Daniel A. Reifsnyder. Speaking at the workshop, t Mr Ramesh …
This document is designed to inform decision makers about additional opportunities to slow the observed rate of climate change and at the same time achieve air quality benefits over the next two to four decades. This can be realised by implementing measures to reduce atmospheric levels of methane, black carbon …
The Ozone Secretariat has released a report of the Environmental Effects Assessment Panel, titled "Environmental Effects of Ozone Depletion and its Interactions with Climate Change: 2010 Assessment." The report outlines the interactions between climate change and the ozone layer, including changes in atmospheric conditions that affect the chemical production and …
Speaking at the Ministerial segment of the Twenty Second Session of the Meeting of the Parties (MOP) to the Montreal Protocol on Substances that Deplete the Ozone Layer held in Bangkok, 11-12 November, Minister of State Kamaludeen high-lighted the critical role that the Maldives is playing as an active member …
The ozone layer that shields life from the sun's harmful rays is projected to recover from harmful chemicals by mid-century, but it will take longer over the polar regions, a United Nations study said on Thursday. Ozone depletion -- blamed for higher ultraviolet radiation that causes skin cancers and cataracts …
Ahmedabad: Watch your usage of refrigerators and air-conditioners. As a byproduct, it releases cloro-floro carbon (CFC) that damages the protective ozone layer and inflicts ultra-violet rays that has side effects ranging from skin cancer to collapse of food pyramid. Gujarat Science City organised seminars and workshops to mark September 16 …
International efforts to protect the ozone layer-the shield that protects life on Earth from harmful levels of ultraviolet rays-are a success and have stopped additional ozone losses and contributed to mitigating the greenhouse effect. The executive summary of the Scientific Assessment of Ozone Depletion 2010 provides new information about the …
Ahmedabad: If you want to leave green footprints and protect the ozone layer, you may want to replace the old refrigerator and air-conditioner, also use less lipsticks, body sprays and other cosmetics. Research has indicated that their usage releases ozone depleting substances. These chemicals make a hole in the protective …
