“…It is remarkable that about two thirds of the longest available neoclimatological temperature record (TCE, see [19,35,39] (TCE data since 1945) does not defeat the COg theory as frequently supposed but highlights the present dominance of natural climatic forcing when compared to anthropogenic forcing. There is a well-founded danger that this situation will not continue in the future decades and centuries.…”

SummaryAnnual, decadal and low-pass filtered annual data of Central England temperature since 1660, northern hemisphere temperature anomalies since 1881, CrOte ice core oxygen isotope ratio since 1160, solar activity since 1160 and volcanic dust concentration since 1500 are analysed in respect to their variability and statistical relationships. An empirical relation between sunspot number and solar irradiation is taken into consideration as well. Estimates of spectral variance and of correlation involving partial and multiple techniques are presented. The long-term variability relationships are substantially more established than it is indicated by the analysis of the annual data. When the variations of the period range T < 30 years are suppressed by means of a Gaussian low-pass filter, 64% of the Central England temperature variance is realized by solar irradiation and volcanic dust parameters. In the case of northern hemisphere temperature anomalies this rate of variance increases to 90%, whereas in the case of Cr~te oxygen isotope ratio it decreases to 26%. ZusmnmenfassungSolare Aktivit~it, Vulkanstaub und Temperatur: Statistische Zusammenh~inge seit 1160 n. Chr. Jahres-, Zehnjahres-und tiefpaf~gefilterte Jahresdaten der Temperatur in ,,ZentralEngland" seit 1660, der nordhemisph~irischen Temperaturanomalien seit 188 I, des Eisbohrkern-Sauerstoffisotopenverh~iltnisses in Crete seit 1160, der solaren Aktivit~it seit 1160 und der Vulkanstaubkonzentration seit 1500 werden beziiglich ihrer Variabilit~it und statistischen Zusammenh~nge untersucht. Dabei findet auch eine empirische Beziehung zwischen der Sonnenfleckenzahl und der solaren Einstrahlung ihre Bert~cksichti-gung. Absch~tzungen der spektralen Varianz und der Korrelation, einschlieNich partieller und multipler Techniken, werden mitgeteilt. Die Beziehungen zwischen den langfristigen Schwankungen sind wesentlich ausgepr~igter als die der Jahresdaten.

“…As the increase of the average surface air temperature in the northern hemisphere from 1880 until the 1940's and the decrease thereafter of over 0.5 ~ reported by Mitchell (1975) and Kukla et al (1977) may represent a portion of a longer-period climatic oscillation, longer records series must be made available. Two sources have been increasingly recognized as important for reconstructing the climate into the pre-instrumental era: historical sources and various paleoclimati4 recorders (proxy data).…”

Abstract. This paper surveys the history of the Earth's climate and deals with facts, techniques, and causes. A review of climatic history since the origin of the Earth demonstrates the changes and variability of our climate along different scales. These variations can probably be fully understood only when taking into account both external forcing and non-linear interactions between the components of the climatic system: atmosphere, oceans, cryosphere, lithosphere, and biosphere. At least, as far as boundary conditions and forcing are concerned for the 108 to 109 yr time scale, atmospheric composition, solar evolution, and tectonism have to be considered, while variations of the Earth's orbital elements, and subsequently of the insolation, best explain the glacial-interglacial occurrences during the Quaternary Period. For shorter time scales, volcanic dust, solar activity, sea surface temperatures, and atmosphere-ocean autovariations have to be taken into account. Furthermore, the man-made effects have now to be considered: atmospheric loading of dust and air pollution particles, changes in surface albedo, and mainly the increasing rise of atmospheric CO 2 and other trace gases adding to a greenhouse effect.This man-made warming effect of future CO2 increase will probably emerge as a clearly recognizable trend against the background of natural climatic fluctuations by the end of this century. This carbon dioxide induced super-interglacial will be superimposed on the expected natural long-term cooling trend of the ice age chronology.
