The report stated that a 20 percent decline in ozone depletion
during the winter months from 2005 to 2016 was expected.
Although warmer-than-average stratospheric weather conditions have reduced ozone depletion
during the past two years, the current ozone hole area is still large compared to the 1980s, when the depletion of the ozone layer above Antarctica was first detected.
The responses of the BDC to the increased GHGs and stratospheric ozone depletion
(Figure 8) show that, as expected, the tropical upward mass flux--in response to both factors--increases (Figure 8(a)), and this is accompanied by increased southern downward mass flux (Figure 8(b)) and northern downward mass flux (Figure 8(c)).
the evolution of the world's response to ozone depletion
The reporting period can best be characterized as a period of transition for the GEF ozone depletion
"The ozone depletion
started quite late, but when it started, it came quite rapidly," Braathen told journalists in Geneva.
has been most severe at the poles, but there has been a seasonal decline of up to 10 per cent at mid-latitudes - a band covering much of North America and Europe.
For example, in the section on ozone depletion
, Hill says, "However, as happens with many environmental issues, there are skeptics.
Research shows that ozone depletion
also may exacerbate the effect of climate change on infectious disease as well as cause immunosuppression by altering T-cells and lymphokine production.
Other factors contributing to the problem are exposure to UV light and ozone depletion
. Prevention efforts thus need to begin at earlier ages, including limiting sun exposure, using protective sunscreens, and immediate dermatological examination of unusual spots on the skin.
over the North Pole reached record proportions this spring, heightening risks of UV-B radiation and sunburn as far south as Italy, according to scientists conducting a five-year assessment of Earth's ozone layer.
But nobody was hearing from them." Instead, on matters such as the banning of DDT, ozone depletion
, and "global warming," the field has been dominated by "popularizers and activists with other agendas," most of whom "wallow in lavish federal funding ...
