Order of the National Green Tribunal (Southern Zone, Chennai) in the matter of Yelahanka Puttenahalli Lake and Bird Conservation Trust Vs State of Karnataka & Others dated 02/05/2025. Pursuant to the tribunal order dated April 24, 2025, Bangalore Water Supply and Sewerage Board (BWSSB) informed the court that as per …
The hole in the ozone layer, the earth's protective shield against ultraviolet rays, is expected to be smaller this year over the Antarctic than last, showing how a ban on harmful substances has stopped its depletion, the United Nations said on Friday. But the hole is probably larger than in …
This issue of WMO annual survey on weather and climate change provides evidence that 2011 had the highest global mean surface temperature levels in a La Niña year. Highlighting a number of climate extremes, it provides evidences of the major impacts of one of the strongest La Niña events of …
The observation of unusually low ozone levels over the Arctic last winter provides reassuring evidence that our knowledge of stratospheric chemistry is robust. Whether such an episode will happen again is an open question.
Chemical ozone destruction occurs over both polar regions in local winter–spring. In the Antarctic, essentially complete removal of lower-stratospheric ozone currently results in an ozone hole every year, whereas in the Arctic, ozone loss is highly variable and has until now been much more limited. Here we demonstrate that chemical …
Washington: The first significant ozone hole above the Antarctic is now as big as North America, scientists have claimed. Spanning about 25 million square kilometers, the ozone hole over the South Pole reached its maximum annual size on September 14, becoming the fifth largest on record, they said. The largest …
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 …
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 …
Geneva: Record loss of the ozone, the atmosphere layer that shields life from the sun's harmful rays, has been observed over the Arctic in recent months, the World Meteorological Organization said.
R. PRASAD The missed data: Looking for long-term patterns in springtime data for the Antarctic helped the team to discover the ozone hole. This file photo shows the ozone hole split into two separate holes. Twenty-five years ago British scientists
Coastal cities and islands all across the world, including India, are facing serious threat from thinning of ice in Antarctica, according to latest research by 100 world-leading scientists from eight countries released here on Wednesday. The Scientific Committee on Antarctic Research, in the first comprehensive review of the state of …
India on Tuesday unveiled its roadmap for phasing out hydrochlorofluorocarbons (HCFC) by 2030 under the Montreal Protocol even as it sought the requisite technology and funds for it from the global community. HCFCs are chemicals now being widely used in refrigeration and air-conditioning in place of chlorofluorocarbons (CFC), which cause …
The ozone hole, which had caused serious environmental concerns, is shrinking and it could fully heal by the end of the century, bringing more rain to eastern Australia, scientists said on Wednesday. Matthew Tulley from Bureau of Meteorology in Melbourne said the hole is now healing because of climate protection …
The World Meteorological Organisation said on Wednesday that the ozone hole is expected to be smaller in 2009 than a year ago. "The meteorological conditions observed so far could indicate that the 2009 ozone hole will be smaller than those of 2006 and 2008 and close to that of 2007," …
The southern ozone hole has changed weather patterns around Antarctica and cooled the air above the east part of the continent, according to new research.
An expansion of sea ice around Antarctica is linked to a hole in the ozone layer high in the atmosphere, according to a study on Tuesday that helps clear up a mystery about global warming. The findings, by scientists at the British Antarctic Survey (BAS) and the U.S. space agency …
