If man-made dust is unimportant as a major cause of climatic change, then a strong case can be made that the present cooling trend will, within a decade or so, give way to a pronounced warming induced by carbon dioxide. By analogy with similar events in the past, the natural climatic cooling which, since 1940, has more than compensated for the carbon dioxide effect, will soon bottom out. Once this happens, the exponential rise in the atmospheric carbon dioxide content will tend to become a… 

Climate Impact of Increasing Atmospheric Carbon Dioxide

It is shown that the anthropogenic carbon dioxide warming should emerge from the noise level of natural climate variability by the end of the century, and there is a high probability of warming in the 1980's.

A CRITIQUE OF THE ANTHROPOGENIC GLOBAL WARMING HYPOTHESIS FROM A TIME-SPACE PERSPECTIVE

The paper reviews the climatic changes that took place during the Quaternary, in particular those of the Holocene, including the historical time. The role of carbon dioxide, as a greenhouse gas, is

Climate Change Prediction

In 1975, Science published my paper “Climate change: Are we on the brink of a pronounced global warming?” ([1][1]). This paper was prompted by the observation that despite an appreciable buildup of

Global Air Pollution and Climate Change

Mankind has now demonstrated that it can change the composition of the atmosphere on a global scale. Those consequences of global air pollution which may have the greatest impact on society in the

Paradigm shifts in late-Holocene climatology?

The climatic consequences of major increases in the concentration of atmospheric carbon dioxide were calculated over 100 years ago, but only during the last two decades have the effects of

When climate change predictions are right for the wrong reasons

Just over 40 years ago, I wrote a paper entitled “Climate change: Are we on the brink of a pronounced global warming?” In it, I attempted to explain why despite a rise in the atmosphere’s CO2 content

When fossil fuel energy was discovered, the timing and intensity of the resulting climate impacts depended on what the natural CO2 concentration in the atmosphere was at that time. The natural CO2

Internally and externally caused climate change

Abstract A numerical climate model is used to simulate climate change forced only by random fluctuations of the atmospheric heat transport. This short-term natural variability of the atmosphere is

The missing part of the greenhouse effect

SummaryGlobal average temperatures from 1860 to 1989 were analysed with a simple fitting procedure. The temperature records can be fitted with a rising exponential up to 1946 and with the same

Impending climatic change and the fate of glaciers

Abstract According to the data of glaciologists, a global warming of the climate may occur in the next 40–50 years. A change in the glaciation of mountains at temperate latitudes in Eurasia, on
