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 ...
There are various areas of linkage between ozone depletion and global warming science: Radiative forcing from various greenhouse gases and other sources. The same CO 2 radiative forcing that produces global warming is expected to cool the stratosphere. [168] This cooling, in turn, is expected to produce a relative increase in ozone (O
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 largest Antarctic ozone hole recorded (September 1985) 2012 retrospective video by NASA on the Montreal Protocol The Montreal Protocol on Substances That Deplete the Ozone Layer [2] is an international treaty designed to protect the ozone layer by phasing out the production of numerous substances that are responsible for ozone depletion.
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 ...
Ozone remains depleted in the midlatitudes of both hemispheres. The global-average total column ozone amount for the period 1997-2001 was approximately 3% below the pre-1980 average values. Models capture the observed long-term ozone changes in northern and southern midlatitudes.
And as global temperatures plummeted, rainfall could drop by as much as 15% because less evaporation would be occurring on the ground, the study findings showed. The ozone layer could also deplete ...
Many industrial products, including refrigerants [8] and other cooling services, use HFCs. [9]Originally, chlorofluorocarbons (CFCs) were used in these applications, but the deleterious effect of these gases on the ozone layer was revealed in 1974 by Paul J. Crutzen, Mario Molina, and F. Sherwood Rowland. [10]
