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).

Warming must occur below the tropopause to increase the net LW flux out of the tropopause to balance the tropopause - level forcing; there is some feedback at that point as the stratosphere is «forced» by the fraction of that increase which it absorbs, and a fraction of that is transfered back to the tropopause level — for an optically thick stratosphere that could be significant, but I think it may be minor for the Earth as it is (while CO2 optical thickness of the stratosphere alone is large near the center of the band, most of the wavelengths in which the stratosphere is not transparent have a more moderate optical thickness on the order of 1 (mainly from stratospheric water vapor; stratospheric ozone makes a contribution over a narrow wavelength band, reaching somewhat larger optical thickness than stratospheric water vapor)(in the limit of an optically thin stratosphere at most wavelengths where the stratosphere is not transparent, changes in the net flux out of the stratosphere caused by stratospheric warming or cooling will tend to be evenly split between upward at TOA and downward at the tropopause; with greater optically thickness over a larger fraction of optically - significant wavelengths, the distribution of warming or cooling within the stratosphere will affect how such a change is distributed, and it would even be possible for stratospheric adjustment to have opposite effects on the downward flux at the tropopause and the upward flux at TOA).

Note that although my original article referred primarily to solar protons I have since decided that the «culprit» is changes in the mix of all particles and wavelengths from the sun in so far as they affect the ozone creation / destruction process differentially at different heights in the atmosphere.

In addition to regional climate change being strongly affected by natural modes of variability, geographic differences in climate change are related to the uneven spatial distribution of aerosols and tropospheric ozone.

He says that the increased solar brightness over the past 20 years has not been enough to cause the observed climate changes, but believes that the impact of intense sunshine on the ozone layer and cloud cover could be affecting the climate more than the sunlight itself.

Note that the inversion at the tropopause is entirely a result of ozone reacting with incoming solar radiation and particles so any change in the ozone creation / destruction balance is going to affect the air circulation below the tropopause.

Changes in ozone depletion may also affect climate change, and many of the chemicals involved in ozone depletion and their substitutes also can influence climate.

Take solar vs. GHGs: 1.5 W / m2 solar change (TOA) over a solar cycle has a large effect in the stratosphere: During a solar cycle, the largest change is in the short waves: 10 % more during high solar activity: that affects ozone building, the temperature in the stratosphere and increases the polewards flow in the stratosphere.

Earth's ozone hole, shown here (in blue) in 2006, could be negatively affected by some efforts to mitigate climate change.

Climate change affects the sources of ozone precursors through physical response (lightning), biological response (soils, vegetation, biomass burning) and human response (energy generation, land use, agriculture).

There are for example biogenic factors reacting to changes in temperature that can not be ignored, affecting surface albedo, ozone levels and cloud formation.

Changes in temperature, humidity and UV radiation intensity brought about by climate change could affect ozone significantly.

In essence: The Sun affects the ozone layer through changes in UV or charged particles.

Also changes in levels of oxygen should affect levels of ozone that is the main greenhouse gas in the stratosphere and is thought to have a very important role in climate.
