The proposition that the average temperature of the earth’s surface is warming because of increased emissions of human-produced greenhouse gases cannot be tested by any known scientific procedure.
It is impossible to position temperature sensors randomly over the earth’s surface (including the 71% of ocean, and all the deserts, forests, and icecaps) and maintain it in constant condition long enough to tell if any average is increasing. Even if this were done the difference between the temperature during day and night is so great that no rational average can be derived.
Measurements at weather stations are quite unsuitable since they are not positioned representatively and they only measure maximum and minimum once a day, from which no average can be derived. They also constantly change in number, location and surroundings. Recent studies show that most of the current stations are unable to measure temperature to better than a degree or two
The assumptions of climate models are absurd. They assume the earth is flat, that the sun shines with equal intensity day and night, and the earth is in equilibrium, with the energy received equal to that emitted.
Half of the time there is no sun, where the temperature regime is quite different from the day.
No part of the earth ever is in energy equilibrium, neither is there any evidence of an overall “balance”.
It is unsurprising that such models are incapable of predicting future climate behaviour, even if this could be measured satisfactorily.
There are no representative measurements of the concentration of atmospheric carbon dioxide over any land surface, where “greenhouse warming” is supposed to happen.
After twenty years of study, and as expert reviewer to the IPCC from the very beginning, I can only conclude that the whole affair is a gigantic fraud.
