The strong sensitivity of the Earth’s radiation balance to variations in the lower stratospheric ozone—reported previously—is analysed here by the use of non-linear statistical methods. Our non-linear model of the land air temperature (T)—driven by the measured Arosa total ozone (TOZ)—explains 75% of total variability of Earth’s T variations during the period 1926–2011. We have analysed also the factors which could influence the TOZ variability and found that the strongest impact belongs to the multi-decadal variations of galactic cosmic rays. Constructing a statistical model of the ozone variability, we have been able to predict the tendency in the land air T evolution till the end of the current decade. Results show that Earth is facing a weak cooling of the surface T by 0.05–0.25 K (depending on the ozone model) until the end of the current solar cycle. A new mechanism for O3 influence on climate is proposed.
I disagree with the authors interpretation of the mechanism involved that is described in part as: increase or decrease of the greenhouse effect, depending on the sign of the humidity changes.
More simply, the Earths radiation balance is much affected by the degree to which incoming radiation is reflected by cloud cover.
I maintain (suggest is too weak a word) that ozone as an absorber of outgoing radiation by the Earth, radiation continuously, day and night, impacting the temperature and relative humidity of the highly reflective ice-cloud-zone that is found from a couple of kilometres above the surface of the Earth unto the limits of the ‘weather-sphere’. The weather-sphere, I would describe as the zone that contains sufficient water vapour to promote the appearance and disappearance of minute, highly reflective, multi-branching (like the international space station) crystals of ice.
Ice crystals reflect and scatter incoming radiation,
There is no need to invoke carbon dioxide or its increasing presence in the atmosphere, or the notion of a greenhouse effect, to explain surface temperature variations. Insofar as carbon dioxide promotes the growth of vegetation and increases the mass of water in the hydro logic cycle it will promote humidity and the formation of more cloud.
The atmosphere ejects heat by virtue of convection. It lacks any of the properties of a greenhouse. The tragic failure of climate science, in the face of overwhelming evidence to the contrary, is to misunderstand the physics of the atmosphere.
The wilfulness of ignorance and the determination to hang on to old dogma is astounding: this paper appeared in 2012.
