Sentences with phrase «ozone amounts change»
Ozone amounts change with the seasons on the planet, as its presence relies on water vapor, which destroys ozone.

Photocopiers are a source of potentially deadly ozone if the filter isn't periodically changed, and it's possible that even very small amounts can cause chest pain and irritation.
«While ozone depletion from dichloromethane is currently quite modest, it is uncertain how the amount of this gas in the atmosphere will change in the future.
Current research combines the climate and chemistry changes in the GISS model to predict future stratospheric ozone amounts both over the polar regions and at lower latitudes.
The number of particles that form, and therefore the amount of chemical ozone destruction, is extremely sensitive to small changes in stratospheric temperature.
The change in total solar irradiance over recent 11 - year sunspot cycles amounts to < 0.1 %, but greater changes at ultraviolet wavelengths may have substantial impacts on stratospheric ozone concentrations, thereby altering both stratospheric and tropospheric circulation patterns... This model prediction is supported by paleoclimatic proxy reconstructions over the past millennium.
As the Antarctic sea ice reached record levels, scientists floated several hypotheses, including possible changes in the ozone hole over Antarctica, or increased amounts of fresh water — which freezes more easily — on the surface of the ocean around Antarctica.
It will not rise at all if the absorption is balanced by an equal amount of emission (as would occur if its emissivity would be increased from a change in its molecular composition — e.g. the formation of ozone from UV radiation or mixing a little CO2 within it).
As an example, variations in the flow of both UV radiation and atomic particles that accompany changes in overall solar activity alter the amount of ozone in the stratosphere.
Scientifically speaking, the change in the amounts of nitrogen oxides and ozone was huge in the uppermost regions where ozone lies.
Thus if the two mid latitude jets move equatorward at the same time as the ITCZ moves closer to the equator the combined effect on global albedo and the amount of solar energy able to penetrate the oceans will be substantial and would dwarf the other proposed effects on albedo from changes in cosmic ray intensity generating changes in cloud totals as per Svensmark and from suggested changes caused in upper cloud quantities by changes in atmospheric chemistry involving ozone which various other climate sceptics propose.
I think it very probable that relatively small changes in the amount of carbon dioxide or ozone in the atmosphere, may have considerable effect on the temperature conditions of the earth.
