I wonder could that have allowed a great deal of extra incoming UV - B to warm surface ozone (both man - made and natural) lending to increased surface temperatures?

On Earth, temperature inversion occurs because ozone in the stratosphere absorbs much of the sun's ultraviolet radiation, preventing it from reaching the surface, protecting the biosphere, and therefore warming the stratosphere instead.
On the other hand, decreasing stratospheric ozone (above 25 km), increasing stratospheric water vapor, and increasing atmospheric CO2 uniformly with height) will produce global surface and tropospheric warming along with stratospheric cooling.
The point being that w / out ongoing decimation from soot, wind, ozone (surface ozone pollution that warms from UV), the AO and greenhouse gases, the ice would have been more likely to recover from the impact of such an event.
With no ozone, the atmospheric temperature would decrease monotonically, and we would instead have to speak of cooling of the «upper atmosphere» in conjunction with the surface warming due to increasing GHGs.
The lack of ozone is chilling the middle and upper atmosphere, altering wind patterns in a way that keeps comparatively warm air from reaching the surface.
Remarkably, the same individuals surface repeatedly - some of the same figures who have claimed that the science of global warming is «not settled» denied the truth of studies linking smoking to lung cancer, coal smoke to acid rain, and CFCs to the ozone hole.
While the buildup of greenhouse gases leads to global warming at Earth's surface, it also cools the stratosphere, which increases the amount of ozone depletion in the polar regions.
Absorption of solar radiation by ozone shields the terrestrial surface from harmful ultraviolet light and warms the stratosphere, producing maximum temperatures of − 15 to 10 °C (5 to 50 °F) at an altitude of 50 km (30 miles).
The various kinds of evidence examined by the panel suggest that the troposphere actually may have warmed much less rapidly than the surface from 1979 into the late 1990s, due both to natural causes (e.g., the sequence of volcanic eruptions that occurred within this particular 20 - year period) and human activities (e.g., the cooling of the upper part of the troposphere resulting from ozone depletion in the stratosphere).
When the intensity of ultraviolet light from the sun increases, temperature rises in this ozone rich air and weakens the downdraft, lowers the surface pressure and with it the strength of the trade winds that blow across the ocean to the low pressure zones that form over the warm waters that accumulate in the west.
In 2010, the Yale Project on Climate Change released a study claiming that «less than half of Americans (45 percent) understand that carbon dioxide traps heat near the Earth's surface, and a majority think that the hole in the ozone layer contributes to global warming.»
6 Ice age — time in the past when continental glaciers covered large parts of Earth's surface Global warming — a gradual increase in the temperature of Earth's atmosphere Greenhouse gas — Gases in the atmosphere, such as carbon dioxide, that trap solar energy Ozone hole — a large area of reduced ozone concentration in the stratosphere, found over Antarctica Chlorofluorocarbon — chlorine compounds that are the main cause of ozone depletion KEY Ozone hole — a large area of reduced ozone concentration in the stratosphere, found over Antarctica Chlorofluorocarbon — chlorine compounds that are the main cause of ozone depletion KEY ozone concentration in the stratosphere, found over Antarctica Chlorofluorocarbon — chlorine compounds that are the main cause of ozone depletion KEY ozone depletion KEY TERMS
Its warm here because Ozone is stopping solar radiation from getting to the surface but this heats up the Ozone.
But the EPA finding was overturned in Federal court, the ozone hole won't be disappearing anytime in the near future, and even with the unrefuted rise in CO2 levels, skeptic climate scientists point out in vast detail how surface temperatures haven't significantly warmed for around two decades.
Collectively the processes produce 20 to 30 year warmer or cooler regimes of Pacific Ocean sea surface temperature — and abrupt shifts between that may be triggered by UV / ozone chemistry modulation of the polar annular modes.
Those factors include stronger winds (which drag warmer water to the surface), human - caused global warming, natural variance and possibly the hole in our ozone layer.
methane concentrations have been increasing in the atmosphere... but NASA do not include it among their 5 indicators of Global Warming (Sea Level, Arctic Sea Ice, Atmospheric CO2 Concentration, Global Surface Temperature, Ozone Hole).
Compute the surface radiative forcing and its amplification by the atmospheric warming in a manner following Myhre and Stordal 1997, using gridded global fields of of the input variables obtained from observations (e.g. the ECMWF reanalysis, ISCCP clouds, satellite ozone, some sort of aerosol optical depth from satellite.
