Sentences with phrase «total ozone changes»

Not exact matches

As for the Northern Hemisphere, Nagashima notes that the decline of total ozone calculated there is statistically significant, but that more calculations are needed in order to understand what the change in ozone really is — and what it means.

There are a large number of recent peer - reviewed scientific publications demonstrating how solar activity can affect our climate (Benestad, 2002), such as how changes in the UV radiation following the solar activity affect the stratospheric ozone concentrations (1999) and how earth's temperatures respond to changes in the total solar irradiance (Meehl, 2003).

Critics of this result might argue that the solar forcing in these experiments is only based on the estimated change in total irradiance, which might be an underestimate, or that does not include potential indirect amplifying effects (via an ozone response to UV changes, or galactic cosmic rays affecting clouds).

ozone, ozone depletion, dobson spectrophotometer, ozone ground stations, total column ozone, genera linear model, dummy coding, trend analysis, deseasonalized trends, antarctic ozone hole, hydrofluorocarbons, greenhouse gases, climate change, stratosphere, troposphere, atmospheric chemistry

That change corresponds to a total change to the GHE of 0.9 °C which I will consider 1 °C as the ozone transfer really takes place in the stratosphere.

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.

Changes in the total solar irradiance (TSI) with enhanced extreme ultraviolet (EUV) emission have been hypothesized to induce a dynamic air / ocean circulation response resulting from stratospheric ozone production (Lean & Rind 1998).

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.

The 28 - year - plus time series of total solar irradiance, total ozone, and outgoing longwave radiation allows researchers to address unique aspects of climate change, climate sensitivity, and cloud feedbacks; however, questions remain.
