The ozone hole was much more seen as a "hot issue" and imminent risk compared to global climate change, [13] as lay people feared a depletion of the ozone layer (ozone shield) risked increasing severe consequences such as skin cancer, cataracts, [23] damage to plants, and reduction of plankton populations in the ocean's photic zone. This was ...
Following the ozone depletion in 1997 and 2011, a 90% drop in ozone was measured by weather balloons over the Arctic in March 2020, as they normally recorded 3.5 parts per million of ozone, compared to only around 0.3 parts per million lastly, due to the coldest temperatures ever recorded since 1979, and a strong polar vortex which allowed ...
The global average amount of ozone 18 miles (30 kilometers) high in the atmosphere won’t be back to 1980 pre-thinning levels until about 2040, the report said. And it won’t be back to normal ...
The Weather Channel A hole in our atmosphere more than twice the size of the United States is finally beginning to close up, and might even be completely gone by the end of the century, according ...
Something strange caused this potentially damaging atmospheric event.
The ozone layer visible from space at Earth's horizon as a blue band of afterglow within the bottom of the large bright blue band that is the stratosphere, with a silhouette of a cumulonimbus in the orange afterglow of the troposphere. The ozone layer or ozone shield is a region of Earth's stratosphere that absorbs most of the Sun's ultraviolet ...
Severe ozone depletion would occur in the stratosphere - the second atmospheric layer as you go upward - due to strong warming caused by the solar absorption of dust particles, the researchers said.
Despite their short lifespan, VSLS have been shown to contribute significantly towards the depletion of the ozone layer, particularly in the lower stratosphere above mid-latitude areas. [6] One study has shown that every five additional parts per trillion by volume (pptv) of VSLS in the atmosphere reducesthe global ozone column by about 1.3%. [7]
