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.
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).
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.
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.
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.
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.
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.
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.
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.
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.
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.
London, Oct 17 (IBNS): Increasing emissions of ozone-destroying chemicals are threatening the recovery of the ozone layer â€“ according to new research from the University of East Anglia (UEA).
