Then, we introduce the chemical mechanisms ...
After the discovery of the Antarctic ozone hole in the 1980s1,2, numerous studies have focused on the future evolution of stratospheric ozone layer depletion given its relevance for life on Earth3. The Montreal Protocol, signed in 1987 with later amendments and adjustments, limits the production ...
Each spring for the past decade the ozone layer in the atmosphere has thinned at the South Pole. Is the loss an anomaly, or is it a sign that the ultraviolet-absorbing layer is in jeopardy globally?
While chemistry-climate models are able to reproduce many characteristics of the global total column ozone field and its long-term evolution, they have fared less well in simulating the commonly used diagnostic of the area of the Antarctic ozone hole i.e. the area within the 220 Dobson Unit ...
Discovery of the Ozone Hole: In 1985, three British scientists named Joe Farman, Brian Gardiner, and Jon Shanklin stunned the world by announcing that a hole developed in the ozone layer during the late winter months of each year. Further, the asserted that this hole was caused by humans ...
“Since the mid-1990s, global ozone levels have become relatively stable,” NASA’s Goddard Space Flight Centerreported in an articlepublished in June 2015. The NASA article continued: “In fact, because of the Montreal Protocol, model si...
The Antarctic ozone hole exerts a substantial impact on the climate of the Southern Hemisphere, yet research exploring its potential influence on the Northern Hemisphere climate is limited. This study unveils a significant positive relationship between interannual variations of Antarctic total column ozone...
The depletion of the ozone hole has also caused an overall cooling trend on the Antarctic continent,this has masked to some extent the effects of warming temperatures, particularly on the larger part of East Antarctica and areas away from the peninsula region. ...
The hole in the Earth’s ozone layer(臭氧层) has until now protected Antarctic from the worst effects of global warming, but scientists have warned that as the hole closes up in the next few decades, temperatures on the continent could rise by around 3℃ on average, with melting ice ...
