Professor Geoffrey G. Duffy, in the Department of Chemical and Materials Engineering of the University of Auckland,
 “Even doubling or tripling the amount of carbon dioxide will virtually have little impact, as water vapour and water condensed on particles as clouds dominate the worldwide scene and always will.”.

Believes that the world is cooling.

This article is oddly similar to one of mine. Details follow:Global Warming and Cooling- The Reality (Wilde)

Climate Change-The Real Causes (Duffy)

The presence of the sun must be a much bigger influence on global temperatures than the greenhouse characteristics of CO2 on it’s own. (Wilde)

The sun clearly must be a much bigger influence on global temperatures than any of the greenhouse gases (Duffy)

The greenhouse effect, as a whole, may smooth out rises and falls in temperature from other causes (Wilde)

the ‘greenhouse effect’ acts as a mechanism to smooth out fluctuations or rises and falls in temperature (Duffy)

The greenhouse effect is mainly a phenomenon of the land surface and the atmosphere (Duffy)

The greenhouse effect is mainly a phenomenon of the land surface and the atmosphere (Wilde)

The strongest sunlight reaching the Earth is around the Equator that is primarily oceanic. The equatorial sun puts heat into the system year in year out whereas loss of heat is primarily via the poles with each alternating as the main heat loser depending on time of year. (Wilde)

The sun’s energy at the equator is consistent all year round, and in this region the larger proportion of surface area happens to be the ocean water. The dominant heat loss is primarily at the poles with each pole alternating as the main loser of heat. (Duffy)

I believe that ENSO switches from warming to cooling mode depending on whether the sun is having a net warming or net cooling effect on the Earth. Thus the sun directly drives the ENSO cycle and the ENSO cycle directly drives global temperature changes. Indeed, the effect appears to be much more rapid than anyone has previously believed (Wilde)

The sun directly drives the El Nino–El Nina current motions that drive temperature changes world-wide( Duffy)

The El Nino Southern Oscillation (ENSO cycle) turns from warming to cooling depending on the net warming or cooling effect of the sun. This occurs quite rapidly (Duffy)

there are similar periodic oscillations in other oceans such as the Atlantic and the Arctic (Wilde)
Also there are similar periodic oscillations in other oceans (Atlantic and the Arctic oceans). (Duffy)

When we compare that with land masses, a lower proportion of heat is reflected from watery zones to participate in the greenhouse effect. (Duffy)
more of the incoming heat is absorbed by water as compared to land and a lower proportion is reflected to participate in the greenhouse effect (Wilde)

The heat from the sun varies over a number of solar cycles which can last from about 9.5 years to about 13.6 years (the main one is the cycle of 11 years). The earth also has an irregular orbit around the sun. These and other effects like the gravitational effects of the planets of the solar system, combine to affect the sun’s magnetic field. Solar fares and sunspots affect the amount of heat generated from the sun
(Duffy)

The heat from the sun varies over a number of interlinked and overlapping cycles but the main one is the cycle of 11 years or so. That solar cycle can last from about 9.5 years to about 13.6 years and appears to be linked to the gravitational effects of the planets of the solar system combining to affect the sun’s magnetic field which seems then to influence the amount of heat generated and incidentally affects the number of sunspots (Wilde)

Professor Duffy has kindly expressed regret for his inadvertent failure to attribute so I withdraw my objection to this article.who is Stephen Wilde?

Stephen Wilde F.R.Met.S. has been a Fellow of the Royal Meteorological Society since 1968. Except he is not.
